Looking for a different Current or Voltage Monitor?

ATC Diversified Electronics UOA-220-AFN is part of the UOA series family of phase/voltage monitors.  The UOA monitor is designed to protect single phase equipment that is required to operate above a certain voltage minimum.  The internal relay will energize when operating voltage is applied above the preset pick up voltage.  The output relay will then de-energize when the voltage falls below the preset drop out voltage for a period longer than the release delay.  The UOA series will then automatically reset when the line conditions return above the preset pick up voltage.
