Model CLSM-05MA/10MA Closed Loop Hall Effect Description Models CLSM-05MA and CLSM-10MA are closed loop Hall effect current/voltage sensors that accurately measure DC and AC currents/voltages and provide electrical isolation between the current/voltage carrying conductor and the output of the sensor. Features • Fast Response • Small Size, Low Cost • High Overload Capacity • Moistureproof, Shockproof • Low Power of Measuring Resistance • Measures DC, AC and pulsed currents/voltages Applications • Variable speed drives for motors • Welding Equipment • Power supply Equipment • Measure and control system • Over current protection • Protection of power semiconductors CLSM-10MA Electrical Specifications CLSM-05MA Nominal current (IN) ................................................... ±5 mA rms ±10 mA rms Current range ........................................................... 0 to ±10 mA rms 0 to ±20 mA rms Voltage input limit (between Vin and Vout).................... 1100 Vrms or DC Max.
