Model CLSM-25

The Model CLSM-25 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.

• Moistureproof, Shockproof

• Measures DC, AC and pulsed currents

Applications

• Variable speed drives for motors

• Welding Equipment

• Power supply Equipment

• Measure and control system

• Over current protection

• Protection of power semiconductors
