M54223 Datasheet Earth Leakage Current Detector

Manufacturer: Unisonic Technologies

Overview: UNISONIC TECHNOLOGIES CO., LTD M54223 LINEAR INTEGRATED CIRCUIT EARTH LEAKAGE CURRENT DETECTOR.

General Description

The UTC M54223 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 M54223 consists of differential amplifier, latch circuit and voltage regulator.

In normal operating, the UTC M54223 should be connected to the secondary side of the ZCT (zero current transformers).

Key Features
