Model CLSM-100
Description
Closed Loop Hall Effect
The Model CLSM-100 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.
Features
• Noncontact measurement of high current
• Measures DC, AC and impulse currents
• Very fast response and high accuracy
• High overload capacity
Applications
•
•
•
•
•
•
Variable speed drives for motors
Welding Equipment
Power supply Equipment
Measure and control system
Over current protection
Protection of power semiconductors

Notes:
1.
Busbar temperature should not exceed 100ºC.
2.
The dynamic performance is the best when the busbar fills the aperture.
3.
Due to continuous process improvement, all specifications are subject to change without notice.
