Marsh Bellofram Diversified Electronics Division UOA Series Single Phase Under Voltage Monitor - 1

UOA Series Diversified Electronics atcdiversified.com 800.727.5646 228 Phase Voltage Monitors // UOA Series The UOA Series offers protection to single phase equipment that is required to operate above a certain voltage minimum. 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.
