The UOA Series Single Phase Under Voltage Monitoring Relay from the ATC Diversified Electronics division of Marsh Bellofram is a family of single-phase voltage monitoring relays, designed to ensure the cost-effective reliable protection of critical equipment that is required to continuously operate above a certain voltage minimum, with the ability to monitor voltage levels up to 240 VAC. The design of the UOA series ensures that when the operating voltage is 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 integral to each series unit provides a differential between pick-up and drop-out trip points.
