Product Description

Product Description

BDM Series Modular Bidirectional DC Power Supply

Power Feature

The BDM Series Modular Bidirectional DC Power Supply is a bidirectional AC-DC module integrating DC power supply and regenerative load into one unit. It features advantages such as wide constant power voltage range, high efficiency, high power factor, high power density and outstanding reliability.

1.Bidirectional energy flow. A single module realizes bidirectional AC/DC and DC/AC conversion with smooth and balanced energy transition.
2.High-frequency isolation. Each modular unit is embedded with a high-frequency isolation transformer, which ensures safe bidirectional energy transfer between the load and the power grid.
3.Fully digital design. Adopts dual DSP full digital control, equipped with multi-level hardware and software protection mechanisms against overcurrent, overvoltage, overtemperature and other abnormal conditions.
