Overview

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 * No potentiomenter required * Direct interface to SCR * Supply voltage derived from AC line-26V shunt * Adjustable sensitivity * Grounded neutral fault detection * 450μA quiescent current * I deal for 120V or 220V sy...
