M54123LK - Brand New UTC IC Chips
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
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 terminal of latch
circuit whose output is suitable 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 is connected to latch circuit’s output
terminal.
FEATURES
- With good input sensitivity current temperature characteristics
- High input sensitivity :VT=6.1mV (Typ.)
- Only need low external component count
- High noise and surge-proof
- Low power dissipation :PD=5mW (Typ.)
- May be used both as 100V and 200V.
- Wide temperature range : from -20 °C to +80°C
