UOA-24-ALA

UOA Series The UOA Series offers protection to SINGLE PHASE equipment that is required to operate above a certain voltage minimum. OPERATION STYLE "A" Style A only STYLE "N" With operating voltage applied above the preset PICK-UP voltage, the internal relay will energize. When the voltage falls below the preset DROP-OUT voltage for a period longer than the release delay, the output relay will de-energize. When line conditions return above the preset PICK-UP voltage, the UOA Series automatically resets and the internal relay energizes. The HYSTERESIS in each unit provides a differential between the PICK-UP and DROP-OUT trip points.
