The MUS series Control Relay for 1-phase voltage monitoring AC/DC. The relay requires no supply voltage but is instead powered by the measurement voltage that it simultaneously monitors (model MUS12DCis only for DC voltage). The MUS Relay provides the user with the opportunity to choose between different control functions over and undervoltage with or without memory (if selected with memory, the power to the relay must be switched off to restart) and a time delay Tt to prevent minor temporary voltage changes (0.1 to 10 seconds). Adjustable hysteresis (H) is 5 to 20% of the set value (applies only to MUS series). All settings are made at the front with a switch and if its setting is changed during operation, all LEDs begin to flash but the unit will continue to function normally with the voltage set at the most recent power connection.

• Three models with different voltage ranges
• Reconnectible over or undervoltage
• Automatic detection of AC or DC
• 17.5mm Cabinet with DIN-rail
