MUS and MUSF voltage control relays monitor single phase DC network voltages. These products monitor their own supply voltage. MUS relays allow the operator to choose between two operating modes: Under/overvoltage and 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.
Control relays monitoring their own power supply. MUS: Over/Undervoltage control selectable latching (memory) function. MUSF: Over/Undervoltage control. Adjustable time delays. Control in 50 Hz, 60 Hz or True RMS measurement. LED status indication
