Datasheet Summary
Low-Power Ground Fault Interrupter
Description The RV4145A 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.
A 26 V Zener shunt regulator, an operational amplifier, and an SCR driver are contained internally. With the addition of two sense transformers, a bridge rectifier, an SCR, a relay, and a few additional ponents; the RV4145A can detect and protect against both hot- wire- to- ground and neutral- wire- to- ground faults. The simple layout and...
