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, and an SCR driver. WIth the addition of two sense
transformers, a bridge recti?er, an SCR, a relay, and a few
additional components, the RV4145A will detect and protect
against both hot wire to ground and neutral wire to ground
faults. The simple layout and conventional design ensure
ease of application and long-term reliability.
