The YCV8-01 from CNC Electric is a compact, high-precision voltage relay that monitors its own supply voltage using True RMS measurement. It supports over-voltage and under-voltage protection, normal/emergency power switching, and reverse running prevention.
Users can select from 8-level rated operating voltages via a knob, with LED indicators showing relay status. The device is DIN rail mountable and includes adjustable time delay settings, reset delay, and hysteresis control.
It’s suitable for site equipment, agricultural machinery, refrigerated trucks, and other mobile or sensitive electrical systems. The relay supports instantaneous release types:
Type B: 3–5×In
Type C: 5–10×In
Type D: 10–20×In
