漏电保护ic v4145

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.
