AC/DC CURRENT SENSOR

CT6876

Raising the Bar for High-Accuracy Measurement

Hioki pass-through AC/DC current sensors are best-in-class devices for use with power meters, Memory HiCorders and high performance oscilloscopes. The CT6876 is a DC to 1.5MHz/1000A sensor, ideal for testing inverter efficiency, inverter output power, reactor or transformer loss. The sensor uses flux gate detection within the zero flux method to deliver outstanding linear properties, enabling it to maintain high precision even at low current levels. CAT III 1000 V
Key Features • The ideal current sensor for measuring large 1000 A currents in EV, HEV, and PHEV • Strengthened shield improves noise resistance to accurately measure current buried in noise • Flat frequency characteristics and CMRR performance to achieve high accuracy measurement • More enhanced environmental resistance performance than ever before with operating temperature range of -40 to 85°C • Basic accuracy of ±0.04% and phase ± 0.1°  • Good frequency characteristics over wide band of DC to 1.5 MHz (amplitude) and DC to 1 MHz (phase) • Ideal for advanced fields such as photovoltaics and fuel cells to evaluate the charge / discharge of batteries and secondary side of inverters • Connect with oscilloscopes or Hioki Memory HiCorders (using SENSOR UNIT) to monitor waveforms
