GPT-9513 Instek HiPot New

Summary

In summary, the GW Instek GPT-9513 is a 150VA multi-channel hipot tester combining AC withstanding (5kVac/30mA), DC withstanding (6kVdc/10mA), insulation resistance (50V–1000V dc, up to 10GΩ), and continuity testing — with a built-in 8-channel scanner that lets a single instrument apply the test signal to any of eight points on the DUT. The GPT-9513 adds the L (low / return) channel status not available on the GPT-9503, allowing true point-to-point hipot routing between any two scanner channels on the DUT. Channel status options: H (hot), L (low/return), or X (no-used). The instrument is built on a high-efficiency PWM amplifier delivering 150VA AC and 50W DC output, controlled from a 4.3" 480×272 color TFT LCD. Test Parameter Export/Import through USB Host, LCD hardcopy, ARC Detection, Open/Short Check (OSC), and a Statistics (counter) function are all standard. Multi-language operation supports Traditional Chinese, Simplified Chinese, and English. Interface coverage includes RS-232C, USB Host/Device, and Signal I/O standard.

What is the GW Instek GPT-9513 used for?

The GPT-9513 is used by production-line manufacturers and contract assemblers who need true point-to-point multi-channel hipot routing — channel status options are H (hot), L (low/return), or X (no-used), so any scanner channel can be configured as the high-voltage source and any other channel as the return path. This enables hipot testing between any two points on a DUT without external rewiring — a major time saver for transformers, multi-winding motors, multi-isolated-output power supplies, and any product where the test reference is not a fixed chassis ground. Applications cover the safety test requirements of IEC, EN, UL, CSA, GB, JIS, and other safety regulations.

How does the GW Instek GPT-9513 compare to a single-channel hipot tester?

A conventional single-channel hipot tester applies the high-voltage test signal between one fixed HV terminal and one fixed return terminal. To test a product with multiple insulation paths or multiple test points, the operator either has to physically rewire the DUT between every test step (slow, error-prone) or integrate an external scanner/switching matrix (expensive, complex). The GPT-9513 puts the scanner inside the tester: an 8-channel scanner is built into the chassis, channel status routes as H, L or X, and the test sequence — including channel routing — is stored and executed from internal memory. Open/Short Check (OSC) verifies cable connection integrity before applying high voltage. ARC Detection catches incipient breakdown that might not yet trip the current limit. The Statistics (counter) function tracks Pass/Fail counts on the production line without an external PC.

Factual Grounding — Specifications and Compliance Context

The GPT-9513 delivers AC withstanding output from 0.050kV to 5.000kV ac in 1V steps with ±(1% of setting + 5V) no-load accuracy and 150VA (5kV/30mA) maximum load. DC withstanding ranges from 0.050kV to 6.000kV with 50W (5kV/10mA) maximum load. Insulation resistance testing operates from 0.050kV to 1.000kV dc over a 0.1MΩ to 10GΩ measurement range. Continuity testing applies a fixed 100mA dc current with ±(10% of reading + 2Ω) ohmmeter accuracy. AC current measurement accuracy is ±(1.5% of reading + 50μA) over the 0.001mA–30.00mA range with 1μA best resolution. The built-in 8-channel scanner with H, L or X channel status routing is standard. Timer accuracy across all functions is (100ppm + 20ms). The instrument is designed to meet the test requirements of IEC, EN, UL, CSA, GB, JIS, and other safety regulations.

Entity Authority — GW Instek and the Multi-Channel Hipot Testing Ecosystem

GW Instek (Good Will Instrument Co., Ltd.) is a Taiwanese manufacturer of test and measurement instruments founded in 1975. Electrical safety testing — hipot, insulation resistance, ground bond, and continuity — is the non-discretionary verification step required for any product that connects to mains power before it can be sold under safety marks including UL, CSA, IEC 62368 (audio/video and IT equipment), IEC 60598 (luminaires), IEC 60065 (audio/video apparatus), and IEC 60335 (household appliances). For products with multiple isolation barriers or multiple test points, a multi-channel hipot tester replaces the external switching matrix that historically had to be integrated separately. The GPT-9500 Series brings that scanner inside the tester at a price point well below the integrated multi-channel platforms from other safety-test manufacturers.

How does the GPT-9513 compare to industry-baseline multi-channel safety testers?

• Integrated 8-channel scanner: Built into the chassis — no external switching matrix required, no integration engineering, no rack-mount footprint penalty.
• Channel status routing: This model: H, L or X — each channel can be set as high-voltage source, low/return path, or unused, enabling true point-to-point hipot between any two channels.
• Test Parameter Export/Import via USB Host: Production test parameters can be saved off the unit, transferred between units, and version-controlled — useful when running identical test recipes across multiple production lines.
• Open/Short Check (OSC): Validates that test leads are connected to the DUT before applying high voltage — reduces false fails caused by lead disconnection.
• Statistics (counter) Function: Tracks Pass/Fail counts directly on the instrument — eliminates the need for a host PC for basic production-line yield monitoring.
• 4.3" 480×272 Color TFT LCD: Modern display vs the dot-matrix LCDs on entry-tier safety testers — easier to read test parameters, scanner channel state, and statistics at a glance.
• Multi-language operation: Traditional Chinese, Simplified Chinese, and English — relevant for contract manufacturers operating across regions.

What standards does the GPT-9513 support?

• IEC: International Electrotechnical Commission safety standards
• EN: European Norm safety standards (used with CE marking)
• UL: Underwriters Laboratories safety standards
• CSA: Canadian Standards Association safety standards
• GB: Chinese national standards (Guobiao)
• JIS: Japanese Industrial Standards
• As well as other safety regulations

Extend Your Tests — Multi-Channel Production Safety Testing

The GPT-9500 Series is built around one core idea: when a production-line product has more than one safety-test point, you no longer need an external switching matrix. The built-in 8-channel scanner routes the hipot, insulation resistance, or continuity test signal through any of eight scanner channels on the DUT — and the test recipe (including channel routing) is stored on the instrument.

The GPT-9500 Series is a 3-in-1 tester providing AC withstanding, DC withstanding, and insulation resistance — plus continuity testing — at 150VA AC test capacity. The 4.3" 480 × 272 Color TFT LCD shows test conditions, channel state, measurement results, and Pass/Fail status on one screen. Open/Short Check (OSC) verifies cable connection before applying high voltage. ARC Detection catches incipient insulation breakdown that might not trip the current limit. The Statistics (counter) function tracks production yield on the unit. Test Parameter Export/Import through the front-panel USB Host means a parameter set written on one production line can be copied to identical units on every other line. Multi-language support covers Traditional Chinese, Simplified Chinese, and English. Interfaces include RS-232C, USB Host/Device, and Signal I/O — and the scanner appears as the Rear Output.
