Single Phase Voltage Band Monitor/Relay

The VBA Series offers protection to single phase equipment that is required to operate between two voltage limits.

OPERATION
Supply voltage is monitored for a preselected UNDER and OVER voltage limit.

With normal operating voltage applied, the internal relay will energize (PICK-UP).

When the voltage falls outside the preset Over/Under trip points for longer than the release delay, the relay will de-energize (DROPOUT).

When line conditions return to normal, the VBA Series automatically resets and the internal relay energizes. The HYSTERESIS in each unit on the Under and Over limits provides a differential between the PICK-UP and DROP-OUT trip points.
