PBO-1P-T: Single Phase Voltage Monitor
Voltage Range:
• 115 to 265VAC, 1Ø
Self-Powered
​
SPDT Relay Contacts
​
4 Built-In Voltage Selections
​
Monitors:
• Over & Under Voltage
• 115 to 265VAC, 1Ø
Operation
The PBO-1P-T monitors 4 single phase voltages with the
tolerances pre-programmed into the PBO.
​
Each time the PBO is powered up, the processor evaluates the line voltage and compares it to the pre-programmed line voltages and tolerances. If the line voltage matches one of the programmed voltages and is within the tolerances, the output relay will be energized and the LED will be green. The PBO will indicate what voltage it is set for by flashing the LED red in a sequence corresponding to the selected voltage.
If a voltage fault is detected, the LED will be red.
