SPDT Contacts


The DPMP is a Digital Phase Monitor that will monitor line voltages from 200VAC up to 600VAC. Actual line voltages and set-up parameters are set via the digital display. The supply voltage must be available during operation. With the supply voltage active, you can set-up all of the DPMP’s settings without the line voltage connected. When the DPMP is connected to the line voltage, it will monitor the line and if everything is within the set-up parameters, the output contacts will be activated. If the line voltages fall outside the set-up parameters, the output relay will be de-enegized after the trip delay. Once the line voltages recover, the DPMP will re-energize the output relay after the re-start time delay (manual to 4 minutes). All settings and the last 4 faults are retained, even if there is a complete loss of power.
