943 standards 450µA quiescent current Ideal for 120V or 220V systems 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.
Contained internally are a 26V zener shunt regulator, an op amp,...
