RV4145A 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.
RV4145A Key Features
- No potentiomenter required Direct interface to SCR Supply voltage derived from AC line
- 26V shunt Adjustable sensitivity
- Grounded neutral fault detection Meets U.L. 943 standards 450µA quiescent current Ideal for 120V or 220V systems
