... Direct interface to SCR • Supply voltage derived from AC line – 26V shunt • Adjustable sensitivity 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 ...
