M54123L Datasheet Earth Leakage Current Detector

Manufacturer: Unisonic Technologies

Overview: UNISONIC TECHNOLOGIES CO., LTD M54123L LINEAR INTEGRATED CIRCUIT EARTH LEAKAGE CURRENT DETECTOR SOP-8.

General Description

The UTC M54123L is a semiconductor integrated circuit with amplifier for a high-speed earth leakage circuit breaker.

For the amplifying parts of earth leakage circuit breaker, the UTC M54123L consists of differential amplifier, latch circuit and voltage regulator.

In normal operating, the UTC M54123L should be connected to the secondary side of the ZCT (zero current transformers).
