Current transformer

Current transformer 25A / measuring range 55A / high accuracy / fast response time / DC, AC and pulse currents

The LEM LAH 25-NP is a reliable current sensor for the precise measurement of direct and alternating currents up to ±25 A (nominal). However, it is capable of processing currents up to ±55 A. Thanks to Hall effect technology, the sensor offers galvanically isolated, non-contact current measurement, ideal for industrial control systems, inverters, solar applications and UPS systems.
