Product Details

• The UOA series offers protection to 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
