Ground Fault Circuit Interrupter (GFCI) Controller, Low Power

Inquiry Add To Bom

RV4145AMT General 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 rectifier, 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.

I'm happy with the quality, and price of this product.

V**k Aug 05, 2023

We walked long enough, everyone came.

C**n Nov 24, 2021

Delivery exactly two weeks. Quality is a shame. Flux is not completely washed. The usb connector is completely not sealed and dangles. The board is removed freely. The plastic plug in the case is not fully inserted. We'll have to finish. In stm32cubeprogrammer the whistle was defined as obsolete. But the firmware was updated successfully-the only plus. Recently, i have a feeling that our, like chinese "friends", send quality goods to everyone, and "daragim rasianam"-all kinds of g.
