Features

• Noncontact measurement of high current

• Measures DC, AC and impulse currents

• Current sensing up to 400A peak

• Very fast response and high accuracy

• High overload capacity

2. The dynamic performance is the best when the busbar fills the aperture.

Model CLSM-50

Description

The Model CLSM-50 is a closed loop Hall effect current sensor that

accurately measures DC and AC currents and provides electrical isolation

between the current carrying conductor and the output of the sensor.

Applications

• Variable speed drives for motors

• Welding Equipment

• Power supply Equipment

• Measure and control system

• Over current protection

• Protection of power semiconductors

Notes:

3. Due to continuous process improvement, all specifications are subject to change without notice.
