LAH 50-P Description

Short technical summary and product information.

The LEM USA Inc. LAH 50-P is a closed-loop Hall effect current transducer capable of measuring DC, AC, and pulsed currents with galvanic separation. It offers a primary nominal RMS current rating of 50A and a measuring range up to ±110A.

 

This sensor operates with a supply voltage of ±12V to ±15V and provides a ratiometric current output. Key electrical specifications include a total error of ±0.25% at nominal current and temperature, a linearity error below 0.15%, and an offset current of ±0.15mA. The frequency bandwidth extends from DC up to 200kHz, with a response time of 0.5µs.

 

Designed for printed circuit board mounting, the LAH 50-P comes in an insulating plastic case recognized according to UL 94-V0. It operates within an ambient temperature range of -25°C to +85°C. The transducer meets EN 50178:1997 standards and offers high immunity to external interference and current overload capability.

 

Applications include AC variable speed drives, 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.
