LEM AHR 500 B10, Current Sensor

The LEM 500 A True RMS Signal Conditioner is a high-performance device designed to measure currents with a nominal value of 500 A and a range up to 2000 A. It features a secondary nominal voltage signal of DC TRMS 0 to 10 V and efficiently processes both AC and DC primary signals. Operating on an external unipolar DC supply voltage of 20 to 50 V, the device boasts an accuracy of 1%, making it highly reliable. It is engineered to function seamlessly across a wide temperature range of -40 °C to 70 °C, utilizing open loop Hall effect technology for precision and dependability.
