SENSOR UNIT

CT9557

Aggregate and measure large currents in multi-cable circuits

Hioki pass-through current sensors and clamp on current probes are best-in-class current sensing devices for use with power meters, Memory HiCorders and high performance oscilloscopes. The CT9557 is 4-channel sensor unit and power adapter for any of the CT686x series, 9709 and CT684x series current sensors and probes that provides waveform and RMS output. Key Features • Power supply for high-precision current sensors with waveform output functionality • Output a single waveform from an aggregate of input waveforms

CE

Measure large currents and multi-cable circuits with aggregate functionality

Once a current sensor has been attached to each branch cable, the CT9557 adds the sensor signals together to create a total signal. Since the sensor unit can treat multiple sensors as a single sensor, the current can be measured using a single power meter.
