The VM500 is a three-phase voltage monitor that protects 3-wire and 4-wire 415 Vac 50 Hz systems. The VM500 will
detect under-voltage, over-voltage, phase loss, phase sequence, phase asymmetry, and neutral failure conditions. Overvoltage and under-voltage trip thresholds can be configured and LED indicators provide fault visibility. Additionally, the device can be easily mounted on a DIN-rail, making it a versatile choice for various applications.
