Voltage Monitor, E1YM400VS10

​The E1YM400VS10 is a multifunctional voltage monitoring relay designed for both single-phase and three-phase systems. Operating at a rated voltage of 400/230V AC with a frequency range of 48 to 63 Hz, it ensures system stability by monitoring undervoltage conditions, phase sequence, and phase failure. The relay offers adjustable thresholds: the maximum threshold ranges from 80% to 130% of the nominal voltage, while the minimum threshold spans 70% to 120%. Additionally, it features an adjustable tripping delay from 0.1 to 10 seconds, allowing for tailored response times to specific application needs. Equipped with a single changeover contact rated at 250V AC and 5A, the E1YM400VS10 provides reliable switching capabilities. Its compact 17.5mm DIN-rail mountable design facilitates efficient installation in control panels. Clear LED indicators provide real-time status updates: red LEDs signal threshold violations and their corresponding tripping delays, while a yellow LED indicates the relay output status. Engineered for precision and durability, the E1YM400VS10 is an ideal solution for safeguarding electrical systems against voltage irregularities and ensuring operational reliability. - Monitoring relays ENYA series - Voltage monitoring in 1- and 3-phase networks - Multifunction - Monitoring of phase failure - Monitoring of phase sequence selectable - Supply voltage = measuring voltage - 1 changeover contact - width 17,5 mm - Installation type
