GV4145A - LOW POWER GROUND FAULT INTERRUPTER

General 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.

Key Features

  • S.
  • 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 systems.

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.
