Hioki recently released its new clamp-type current sensors: AC/DC current probes CT6841A, CT6843A, CT6844A, CT6845A, and CT6846A. The conventional clamp-type current sensors have the convenience of measuring current without having to disconnect the measuring cable.

Features

1. Highly accurate DC current measurement
Measurement accuracy has been improved from ±0.3% to ±0.2%. Highly accurate DC current measurement has been achieved by improving the structure of mounting part of the clamp tip and the optimized design of the magnetic circuit.

2. No need for special setting for high accuracy measurement
Hioki’s high precision power meter “Power analyzer PW8001” can be connected to different types of current sensors depending on the measurement. In order to measure the power accurately, the current sensor must be set correctly. The new AC/DC current probes are automatically set up by simply connecting to the PW8001. The new AC/DC current probes transmit the internal recording information, such as model name, serial number, calibration data and provide much accurate power measurement than before. This function prevents incorrect measurement due to operator setting error and enables measurements to be taken immediately.

3. Improved basic performance
The new AC/DC current probes not only provide improved accuracy, but also improved frequency band performance. CT6841A, which has the widest bandwidth has succeeded in improving performance up to 2MHz. CT6841A enables reliable measurement of high-frequency power in electric vehicles and PCS (power conditioning subsystem for solar power).

Main applications

– Power measurement in the WLTP fuel efficiency performance evaluation test of vehicles.
– Power measurement of batteries for electric vehicles.
– Efficiency evaluation of PV inverter (power conditioner for solar power).

Anticipated Customers

– Automotive manufacturers, especially of ecological vehicle such as EVs and FCVs (fuel cell vehicles).
– Electric component manufacturers of devices such as transformers, motors, and reactors.
– Renewable energy-related manufacturers of equipment such as wind and solar power generators.
– R&D engineers dealing with power supply equipment.
