UNISONIC TECHNOLOGIES CO., LTD
GV4145A
LINEAR INTEGRATED CIRCUIT
LOW POWER GROUND FAULT
INTERRUPTER
 DESCRIPTION
The UTC GV4145A 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
opamp, and an SCR driver. With the addition of two sense
transformers, a bridge rectifier, an SCR, a relay, and a few
additional components, the UTC GV4145A will detect and protect
against both hot wire to ground and neutral wire to ground faults.
Ease of application and long-term reliability.
 FEATURES
