TECHNICAL DATA
Low Power Ground Fault Interrupter
IL4145A
The IL4145AN is a low power controller for AC outlet ground fault interrupters.
These devices detect hazardous grounding conditions, such as equipment (connected to opposite phases of the AC line) in contact with a pool of water and open circuits the line before a harmful or lethal shock occurs.
Contained internally are a 26V zener shunt
regulator, an op amp, and an SCR driver.
With the addition of two sense transformers, a bridge rectifier, an SCR, a relay, and a few additional components, the IL4145AN will detect and protect against both hot wire to ground and neutral wire to ground faults.
The simple layout and conventional desi...
