VBA-240-ALA

STYLE "A" OPERATION 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 (DROP-OUT). 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. VBA Series The VBA Series offers protection to SINGLE PHASE equipment that is required to operate between two voltage limits. Supply voltage is monitored for a preselected UNDER and OVER voltage limit. STYLE "N" WIRING E55826 Style A only Single Phase Voltage Band Monitor POWER REQUIRED Models Up To 110 VDC: 3 Watts, Max.
