ICA UPS ST-623B Capacity 1200 VA/600W, inverter works only when the AC input voltage low or loss. When the AC input voltage in normal condition, ICA UPS will stabilize and filter the AC input voltage and supply a clean and stable AC voltage to the ICA UPS output and charge the battery. When the AC input voltage low or loss inverter will replace it and supply a stable AC voltage within a very short transfer time
