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
CT9557 | For the CT6841-05, etc., ME15W connector |

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.
Connectable current sensors | Current sensors with a Hioki ME15W (male) output connector (CT686x-05, 9709-05, CT684x-05, etc.) *The separately available Conversion Cable CT9900 is required in order to use a current sensor equipped with a PL23 (10-pin) terminal |
