Overview
UNISONIC TECHNOLOGIES CO.
, LTD M54123L LINEAR INTEGRATED CIRCUIT EARTH LEAKAGE CURRENT DETECTOR „ 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).
Here the ZCT detects leakage current different amplifiers’ both input.
Then the signals which have been amplified are integrated by an external capacitor.
The integrated signal connects to the input ter...
