LEM HAL 400-S

Product Overview

The HAL 400-S from LEM is a current transducer. It features instantaneous output, easy installation, low power consumption, small size and space saving, wide current range and high immunity to external interference. 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.
