AC/DC CURRENT SENSOR
CT6877
Hioki pull-through AC/DC current sensors are best-in-class devices
for use with power meters, Memory HiCorders and high performance
oscilloscopes. The CT6877 is a DC to 1 MHz/2000A sensor, ideal for
capturing current signals from switching power supplies, inverters,
power conditioners, etc.
CAT III 1000 V
Key Features
- Easily measure large 2000A currents to meet applications in EV, HEV testing
- Improved noise resistance performance through a stronger shield lets you accurately measure current buried in noise
- High accuracy measurement realized through flat frequency characteristics and CMRR performance
- More enhanced environmental resistance performance than ever before lets you measure in -40 to 85°C situations
- Improved basic accuracy of ± 0.04% and phase accuracy of ± 0.1°
- Superior frequency characteristics of DC to 1 MHz (amplitude)
- Meet a wide range of applications from measuring battery charge/discharge to the secondary side of inverters in photovoltaic power generation and fuel cell evaluation, etc.
- Monitor waveforms when paired with oscilloscopes or Memory HiCorders and Sensor Unit
