LEM莱姆 LA 55-P 电流传感器
LEM LA 55-P CURRENT SENSOR, CLOSED LOOP, 70A, 1US Product Q&A Hi. I have a question about how to apply the LA 55-P current transducer in the circuit.
LEM
The LA 55-P from LEM is a current transducer. It features instantaneous output, excellent accuracy, very good linearity, low temperature drift, optimized response time, wide frequency bandwidth, no insertion losses, high immunity to external interference and current overload capability. This current transducer is used for the electronic measurement of currents (DC, AC, pulsed, mixed) with galvanic separation between the primary circuit and the secondary circuit. It is mainly used in AC variable speed drives and servo motor drives, static converters for DC motor drives, battery supplied applications, Uninterruptible Power Supplies (UPS), Switched Mode Power Supplies (SMPS) and power supplies for welding applications. Closed loop current transducer using the hall effect technology Primary nominal current of 50A 0.65% accuracy Primary current measuring range is ±70A Supply voltage range from ±12V to ±15V Conversion ratio is 1 : 1000 Secondary nominal rms current is 50mA Insulated plastic case recognized according to UL 94-V0 Operating temperature range from -40°C to 85°C PCB mounting Sensor Output: Closed Loop Supply Voltage DC Min: 12V Supply Voltage DC Max: 15V Current Measuring Range DC: -70A to 70A Current Measuring Range AC: -70A to 70A Response Time: 1µs Accuracy %: 0.65% Product Range: LA 55-P Series Accuracy: ± 0.65% SVHC: To Be Advised Find similar products grouped by common attribute
