M54123L LINEAR INTEGRATED CIRCUIT
EARTH LEAKAGE CURRENT DETECTOR
DESCRIPTION
The UTC M54123L is a semiconductor integrated circuit withamplifier 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 beconnected 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 connectsto the input terminal of latch circuit whose output issuitable for the characteristics of high- speed earth leakage circuit breaker.
Until the input voltage reaches the fixed level, latch circuit doesn’t become high. Then drives a thyristor which isconnected to latch circuit’s output terminal. Once the trigger latch circuit, only the power on again to reset.
FEATURES
M54123L 線性集成電路
漏電電流檢測器
描述
UTC M54123L 是一種帶放大器的半導體集成電路，用於高速漏電斷路器。
對於漏電斷路器的放大部分，UTC M54123L由差分放大器、鎖存電路和穩壓器組成。
在正常操作中，UTC M54123L 應連接到 ZCT（零電流互感器）的次級側。此處 ZCT 檢測不同放大器的兩個輸入的漏電流。
然後將放大的信號通過外部電容器進行積分。集成信號連接到鎖存電路的輸入端，其輸出適合高速漏電斷路器的特性。
在輸入電壓達到固定電平之前，鎖存電路不會變高。然後驅動連接到鎖存電路輸出端的晶閘管。一旦觸發鎖存電路，只有重新上電才能複位。
