... Overview MUS and MUSF voltage control relays monitor single-phase DC network voltages. These products monitor their own supply voltage. MUS relays allow the user to choose between two operating modes: - Under/overvoltage - With or without fault latching An adjustable time delay, on threshold crossing, provides immunity from transient phenomena, thus preventing spurious triggering of the output relay. ...

... fast-blow fuse or cut-out MUSF relays operate in window mode: they check that the controlled voltage stays between a minimum and maximum threshold. The under and overvoltage threshold values are set by two graduated potentiometers by reading the Un scale to be monitored directly. The hysteresis is fixed, value the preset thresholds. ...
