In summary, the GW Instek GPT-12003 is a 200VA AC/DC withstanding, insulation resistance, and continuity safety analyzer compliant with IEC 61010-2-034 — combining AC hipot (5kVac/40mA), DC hipot (6kVdc/10mA), insulation resistance (50V–1200V dc, displays to 50GΩ), and continuity testing in one compliance-grade chassis. It is built on a high-efficient PWM amplifier that excludes the influence from fluctuating input voltage or distorted waveforms, runs a 7" color TFT LCD, and supports the Sweep Function for DUT characteristic analysis, Statistic Function (60,000 lots maximum), Capacitive Load Testing Capability up to 47μF, and USB Storage for automatic test result archiving as .txt files. IEC 61010-2-034 compliance — the standard that governs how high-voltage measurement equipment must be designed — is the architectural distinction that separates this analyzer from conventional safety testers.
The GPT-12003 is used by manufacturers and contract assemblers who need IEC 61010-2-034-compliant AC withstanding, DC withstanding, insulation resistance, and continuity testing in one chassis. AC and DC hipot verify the insulation barrier between live circuits and accessible parts at high voltage; insulation resistance is a lower-voltage DC measurement (50V–1200V) of actual insulation resistance — used for periodic verification, incoming inspection, and trending degradation over a product's service life. The GPT-12003 displays IR up to 50.00GΩ with 0.1MΩ resolution and a 10mA pre-charged current (fixed) that first rapidly charges the DUT's capacitive load and then conducts the measurement, avoiding misjudgment from fluctuating inrush current.
The GPT-12003 complies with IEC 61010-2-034 (Safety requirement for electrical requirement for measurement, control and laboratory use – particular requirements for measurement equipment for insulation resistance and test equipment for electric strength) — the standard that specifies how high-voltage measurement equipment must be designed to protect the operator. Conventional safety testers focus on the DUT's safety; the GPT-12000 Series additionally certifies the test setup's safety through double insulation, retracted START key, high illumination LED warnings, and automatic post-test DUT discharge to approximately 30V. Capacitive Load Testing Capability up to 47μF lets the analyzer reliably test DUTs with large EMI filter capacitors, surge absorbers, and other high-capacitance loads.
The GPT-12003 delivers AC withstanding output from 0.050kV to 5.000kV ac in 1V steps with ±(1% of setting + 5V) no-load accuracy and 200VA (5kV/40mA) maximum load, with 1μA current measurement resolution and ±(1.5% of reading + 30μA) accuracy, DC withstanding from 0.050kV to 6.000kV with 50W (5kV/10mA) max load and 0.1μA best resolution, insulation resistance from 50V to 1200V dc with display ranges to 50.00GΩ, and continuity testing at 100mA dc fixed over a 0.10Ω to 70.00Ω range with 0.01Ω resolution. Memory: 100 MANU + 100 AUTO blocks with 10 manu per auto. Test data is automatically saved to USB as a .txt file on each START press when USB Storage is activated. Power consumption is 400VA max. from an AC 100V~240V ± 10%, 50Hz/60Hz universal input.
GW Instek (Good Will Instrument Co., Ltd.) is a Taiwanese manufacturer of test and measurement instruments founded in 1975. The GPT-12000 Series is the world's first safety analyzer to comply with IEC 61010-2-034 — the IEC standard that governs the safety design of measurement equipment for insulation resistance and test equipment for electric strength. The standard requires that the software and hardware interfaces of high-voltage measurement instruments be designed so that users are provided with necessary protection and warning during operation — covering double-insulation design, output isolation, retracted activation controls, high-visibility warning indicators, and automatic post-test DUT discharge. The GPT-12000 Series is engineered to meet the test requirements of safety standards such as IEC, EN, UL, CSA, GB, JIS that govern test requirements for various electronic/electrical products or parts — and the analyzer itself meets the IEC 61010-2-034 safety requirements that govern the analyzer's own operator protection.
GW Instek introduces the flagship model (200VA output capacity) safety analyzer — the GPT-12000 series, which is the first safety analyzer in the world to comply with IEC 61010-2-034 (Safety requirement for electrical requirement for measurement, control and laboratory use – particular requirements for measurement equipment for insulation resistance and test equipment for electric strength), which stipulates that the requirements of the software and hardware interfaces must be followed while designing high voltage and insulation resistance test and measurement instruments so as to ensure that users are provided with necessary protection and warning while using the instruments.
The GPT-12000 series safety analyzer has four models: GPT-12004 features AC/DC withstanding voltage test, insulation resistance test, AC ground bond test and continuity test; GPT-12003 conducts AC/DC withstanding voltage test, insulation resistance test, and continuity test; GPT-12002 carries out AC/DC withstanding voltage test and continuity test; GPT-12001 executes AC withstanding voltage test and continuity test. The entire series provides an output capacity of 200VA and utilizes a high-efficient PWM amplifier to effectively exclude the influence from the fluctuating input voltage or distorted waveforms so as to guarantee a stable high-voltage output while conducting AC withstanding voltage test on the DUT to meet the safety regulations such as IEC, EN, UL, CSA, GB, JIS that demand the test requirements for various electronic/electrical products or parts.
To comply with IEC 61010-2-034 requirements, the series takes into account of safety by adopting the double insulation design for input power supply and output voltage to enhance user safety. Additionally, the retracted on-off switch design (START key) and various (optional) mechanisms for test activation (for instance, press and hold for 1 second to activate, activation by pressing double keys, etc.) are incorporated into the series to avoid accidentally touching that results in high voltage/large current output causing damage and danger to products or users. High illumination LED lights (flashing or permanently lit) and a high volume audial indicator are included in designing the series to provide warnings of the status of the on-going tests or judgement results from the safety analyzer. On top of that, the DUT will be automatically discharged to the safe voltage (approximately 30V) after each test to prevent large residual test voltage from causing harm to users.
The series utilizes 7-inch color TFT LCD and inherits the consistent simplicity key design style of the product family to allow users to experience easy operations and a clear observation of the test results. The major test functions include AC withstanding voltage test (AC 5kV/40mA), DC withstanding voltage test (DC 6kV/10mA), insulation resistance test (DC 50V~1200V/50GΩ max.), ground bond test (AC 32A/650mΩ max.), and grounding continuity test (DC 100mA fixed/70Ω max.). The series also collocates with superb output adjustment resolution, measurement resolution (AC withstanding voltage: 1μA; DC withstanding voltage: 0.1μA; insulation resistance: 0.1MΩ; ground bond: 0.1mΩ; continuity test: 0.01Ω), controllable voltage ramp up and ramp down time settings, and upper/lower limit judgement settings, and large capacitance test capability (up to 47uF) for DUT with large capacitance such as surge absorber and large capacitance on the input terminal of EMC/EMI prevention. For Insulation resistance, provides 10mA pre-charged current (fixed) to first rapidly fully charge the DUT's capacitive load and then to conduct test and measurement so as to avoid misjudgment from fluctuating inrush current.
Providing the markets with safe electronic products is the responsibility of every manufacturer! Similarly, safety analyzer that tests whether electronic products meet safety regulations must attach the importance to the safety it provides! GPT-12000 is the world's first safety analyzer to comply with IEC 61010-2-034 (Safety requirement for electrical requirement for measurement, control and laboratory use – particular requirements for measurement equipment for insulation resistance and test equipment for electric strength). Apart from this, the safety considerations also include double insulation for input and output voltages, safe output/warning mechanism, post-test discharge mechanism, etc. to ensure user safety during the operation.
For production tests and characteristic verification, the GPT-12000 series provides a withstand voltage test voltage (AC 5kV/DC 6kV) that can be adjusted in 1V steps with current measurement resolutions up to 1μA (ACW) or 0.1μA (DCW) to realize the small leakage current measurement for products or components. In addition, the insulation resistance test voltage can be adjusted in 50V steps from a DC output range of 50V to 1200V, and the resistance measurement resolution can reach 0.1MΩ. Since most safety regulations require AC power supply for ground bond test, the GPT-12000 series provides 8Vac (open) and 3A to 32Aac current for ground bond test with a resistance measurement resolution of 0.1mΩ. The entire series provides the continuity grounding test function with a 100mAdc (fixed) test source and a measurement resolution of 0.01Ω to detect if the tested equipment is correctly grounded.
To make tests compliant with the test requirements of relevant safety regulations, the GPT-12000 series provides a more flexible output sequence setting starting from the start point of the test. Taking the AC/DC withstand voltage test as an example, the initial voltage can be set. Users determine the initial voltage ratio (i.e., the ratio of the rated test voltage), and then the voltage ramp up can also be set to reduce the risk of insulation breakdown or damage to the DUT caused by transient high voltages. After the rated test voltage is reached, the upper/lower limit judgement window, delay judgment and test timer mechanism can be set to assist users to conduct tests smoothly and correctly. The new voltage ramp down time setting allows users to test with a ramp down voltage to avoid the impact of excessively high rated test voltage to instantaneous discharge on the DUT.
With respect to the insulation resistance test, other than the newly added grounding mode to perform test in accordance with the actual grounding state of the DUT, the setting mechanism of the supplementary upper/lower limit judgement is also added to shorten the test time. The user-definable mode mechanisms include: STOP ON FAIL: The test is terminated as soon as the FAIL setting is met; STOP ON PASS: The test is terminated as long as the PASS setting is met, or TIMER: judgement is conducted when the timer time is reached.
The GPT-12000 series features a unique sweep function, which displays a curve diagram of the test results of the DUT. Test readings are recorded point by point based on the applied test voltage or current and relevant settings (such as initial voltage, ramp up time, test time, or ramp down time). After the test is completed, users can learn the amount of applied energy (voltage or current) at a specific time point and the results of measurement parameters by moving the cursor position so as to help users understand the changes of the measurement parameters (current or resistance) during the test. The function can also be used to determine the critical break down of the DUT.
With respect to the automatic test function, each automatic test has up to 10 manual test items and all related settings and result judgement are presented in a table, so that users can easily obtain the results of all test items at a time. Other than that, if there are multiple automatic test connection requirements, users only need to select CON in the last item of the table to automatically connect the automatic measurement of the next position (such as AUTO-012~AUTO-013).
The GPT-12000 series provides the statistic function, which can record the test functions and judgment results in the temporary storage area (60,000 lots max.). Users can immediately learn the test of each function during the test without using a PC. The distribution of the good products can be analyzed to understand the quality of the batch based on the data. If most of them fall at the critical point that is close to be categorized as defect product, the results can be found in the test process in time so as to improve the manufacturing process and stop the defect products from entering the markets to ensure the reliability of products after leaving the factory.
In order to facilitate users to analyze the results of the safety test, GPT-12000 provides the USB storage function in addition to its own statistic and analysis functions. When a USB is inserted and the storage function is activated, each time the test button (START) is pressed, the test results of all tests (every manual or automatic test item) are automatically saved to the USB in the form of a text file (txt) for follow-up analysis. For interface connections, the GPT-12000 series offers external control or a variety of remotely connected ports such as a signal I/O port that can be used to connect an external controller or PLC. The signal I/O's output signal pins can be self-defined so as to collocate with various PLC control requirements. Besides, the entire series is equipped with RS-232C and USB device (GPIB is optional) for easy retrieval of test data and results by connecting a PC.
