Three-phase uninterruptible power supply PZL-03 HF

DCACwith built-in battery

It is widely applied in the hydropower plant, the thermal power plant, the substation and other fields needing DC devices (like power generation plant, substations, power distribution station, petrifaction, steel, electrified railways and real estate, etc.), so as to supply the large-power DC power. It is meanwhile used as the reliable emergency power in the communication sector, computer room, hospital, mining and factory, hotels and high buildings.
