Digital monitoring relay Voltage monitoring, 22.5 mm from 10 to 600V AC/DC above and below supply voltage: AC/DC 24 V DC and AC 50 to 60 Hz without galvanic isolation to the measuring circuit Disturbance delay 0.1 to 20 s Hysteresis 0.1 to 300 V 1 changeover contact with or without fault memory Screw connection Successor product for 3UG3532-1AC. SIRIUS 3UG4 digitally adjustable voltage monitoring relay for monitoring voltages that are too high or too low, e.g. to protect a system from damage, to protect against deep discharge of batteries or to switch a system on at a defined voltage.Worldwide use through international certificates. The relay can be set variably to over-, under-shoot or window monitoring. Delay times and RESET behavior can be freely parameterized. Less space required in the control cabinet thanks to a narrow width. Reliable diagnostics by displaying ACTUAL value and status messages. All versions with removable connection terminals.In addition to screw connection techno
