# Hioki CT6863 200A AC/DC Current Sensor # Hioki CT6863 200A AC/DC Current Sensor ## Key Features At A Glance - AC/DC current sensing across the series with 50 A, 200 A, and 500 A rms rated models - Bandwidth ranging from DC to 1 MHz at the top of the series down to DC to 100 kHz - Basic accuracy of ±0.05% rdg. ±0.01% f.s. ±0.2 deg (DC and 16 Hz ≤ f ≤ 400 Hz) - Voltage output of 2 V at rated current with 50 Ω output resistance - Maximum accuracy of ±0.16% when used with the POWER ANALYZER 3390 - Maximum rated voltage to earth of AC/DC 1000 V (50/60 Hz), measurement category III (CAT III 1000 V) - Compatible with the 3193 (with 9602), 3194 (with 9602), 3390, and PW6001 power meters - 3 m cord length; supplied with an instruction manual and six mark bands The HIOKI CT6862, CT6863, and 9709 are wide-bandwidth, high-precision AC/DC current sensors that achieve high-accuracy measurement of both small- and large-current signals. Each model provides an isolated current input that converts the measured conductor current into a proportional voltage output — 2 V at the rated current — with a 50 Ω output resistance, allowing the measured signal to be carried to a connected power meter without the long signal-cable effects of a direct connection. Across the series these sensors support a wide variety of applications in the fields of electric and hybrid electric vehicles, inverters and other devices, and alternative energy sources such as solar power and fuel cells, as well as home electronic appliances and system equipment. They are also suited to comprehensive evaluation of wide-bandwidth, high-precision inverter motors, and to measurements including battery charge and discharge and inverter secondary-circuit measurement. ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, so the instruments you order are units we keep on hand rather than sourced on demand. ## Compare Other Models in This Series The HIOKI AC/DC current sensor series comprises three models — the CT6862, CT6863, and 9709 — that share a common high-precision, wide-bandwidth measurement approach but differ in rated current and frequency characteristics. All three deliver a 2 V output at rated current, a 50 Ω output resistance, and the same basic accuracy specification, and all carry a maximum rated voltage to earth of AC/DC 1000 V at measurement category III. Each model is also offered in a standard version and a -05 version with a 12-pin terminal, giving the CT6862 / CT6862-05, CT6863 / CT6863-05, and 9709 / 9709-05 order codes. The choice between models is driven primarily by the current level and bandwidth a given measurement requires. Each model below links to its own dedicated product page with new-condition pricing. Select the model that matches your required rated current and bandwidth, then choose the new unit on that model's page. The models are distinguished by rated current and bandwidth: the CT6862 is rated at 50 A AC/DC with a bandwidth of DC to 1 MHz, the CT6863 at 200 A AC/DC with DC to 500 kHz, and the 9709 at 500 A AC/DC with DC to 100 kHz. Higher rated current in the series corresponds to a lower upper bandwidth limit, so the model selection balances the current to be measured against the frequency content of interest. Mechanical and conductor-handling differences accompany the electrical tiers, including measurable conductor diameter (26 mm or less, and 36 mm or less depending on model) and physical size and mass. See the comparison table that follows for the per-model rated current, bandwidth, output, dimensions, and accuracy-guarantee period.
