Spec Sheet and Wiring Diagram |

RELAY OVERVIEW
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. |
