PT.Catu Power Initiative is a Manufacturer of Diode Droper. Working Principle of Diode dropper is the additional equipment on the DC-system ( Rectifier / Charger-Battery) , which serves to maintain a large voltage into the load is always within the allowable range of load voltage, although voltage Rectifier / Charger changed, so as not to damage the load. Diode dropper will work at the time Rectifier / Charger works well ( the main ration is not an interruption occurs)
