When a harmful condition is detected, the LPVRB’s output relay is deactivated after a specif ied trip delay. The output relay reactivates after power line
conditions return to an acceptable level for a specif ied amount of time (Restart Delay) or after a manual reset . The trip and restart delays prevent nuisance
tripping due to rapidly fluctuating power line conditions.
50 Hz system. An adjustment is provide to set the normal line voltage from 190-240 or 380-480 VAC. Other adjustments include a 1-30 second trip delay,
a 1-500 second restart delay, and a 2-8% voltage unbalance trip adjustment .
with a jumper installed for automatic restart . A connector with 12” wires is included for manual reset switch.
The Model LPVRB automatically senses whether it is connected to a 190 to 240V 60 Hz system, a 440 to 480V 60 Hz system, or a 380 to 416V
Two LEDs indicate the status of the Model LPVRB; Run Light , Under Voltage, Over Voltage, Phasing Fault/Reverse Phase, and Manual Reset . The LPVRB ships
A unique microcontroller-based voltage and phase sensing circuit constantly monitors the three phase voltages to detect harmful power line conditions.
