The DPR 4000B Series is a single phase rectifier with outstanding efficiency and power density. Beside the energy saving by power conversion, the extended temperature range support significant additional energy saving opportunity for the site cooling. The wide input voltage range and inbuilt AC overvoltage protection make this product very robust for regions with difficult AC utility quality. The powerful rectifier provides the necessary power for fast battery charging in emerging markets with the best possible system configuration.
Installation is simplified as all Delta rectifiers have their connectors at rear and are hot-pluggable. Fan cooling with speed control ensures near silent operation. The advantages of the product are the compactness for applications requiring medium to high power.
