Physical Characteristics
AC Input AC input is connected when switch is in ON position and AC input is cut off in OFF position
Battery Charge With AC input and no connection to battery, yellow light on. When connecting to battery and charging, yellow light blinks. When AC cuts off and battery discharges, yellow light on.
Battery Trigger Switch When connecting to battery without AC input, please press the white switch to trigger the battery discharge
DC Output With DC output, green light on. Without DC output, green light off.
Low Battery Alarm In battery discharge, red light is on when voltage is lower than 11±0.4V.
