CONTROLS CONTROLS SR SERIES UNDER VOLTAGE RELAY UL listed • • • • CSA recognized Multiple AC/DC Voltages 5 to 20% Hysteresis Adjustment Automatic Operation Adjustable Threshold Threshold hysteresis R 0 t The voltage threshold SR Relay controls a voltage supply which is its own supply. The output relay is energized when the supply (effective for AC) exceeds the selected threshold. It de-energizes when the controlled supply falls below (5 to 20% Hysteresis) of the supply voltage or when the input power breaks. Hysteresis is controlled by a potentiometer and its selection does not change the chosen threshold. Pulses or drops of 100ms or less are ignored.
