Designation:
VOLTAGE MONITORING RELAY 3-P
Part No.:
MRU32/UC12-48V
Description:
Voltage monitoring relay for 3-phase applications with measuring range from 0,1 to 480 VAC or 0,1 to 690 VDC. This device contains three monitoring functions - low limit, high limit and window - with adjustable alarm delay on its output relays. The LCD shows the measured values and permits an accurate setting of the parameters. The device includes a LED indication for the alarm status.
