Description

Cycling display of three phase (single phase) voltage It, s a comprehensive digital voltage protector equipped with a MCU (microcontroller). Multiple protection functions such as overvoltage, undervoltage, open phase, reverse phase, three phase unbalance protection Separate setting of overvoltage, undervoltage, overvoltage delay time and undervoltage delay time Manual reset and automatic reset are optional, and the automatic reset time can be set to be 1s or 5s. Functional setting by dial switch Three phase voltage unbalance (phase voltage difference above 5%) protection, with delay time of 3s Fail safe Digital display of fault reason and fault voltage, facilitating fault handling
