Product Description

Product Description

BD Series High-Precision Bidirectional DC Power Supply

Power Feature

The BD Series High-Precision Bidirectional DC Power Supply adopts a two-stage conversion topology with IGBT devices. It is a high-precision, highly reliable, programmable and automatically operable DC power supply. Its DC output delivers high precision and excellent dynamic response, as well as automatic bidirectional operation. Equipped with fully digital control, the unit features high control accuracy, fast response speed and a wide output adjustment range. With programmable output functions, it can be applied to diverse working conditions via different control configurations.

1.Built-in power frequency isolation transformer plus AC/DC LC filter to achieve electrical isolation between input and output terminals.
2.Two-stage conversion with Infineon high-voltage IGBT modules, constituting a fully digital power-frequency isolated power supply.
3.Capable of feeding regenerative energy back to the grid, with dual characteristics as both a power source and an electronic load.
4.Phase-shifted carrier circuit applied on the DC-DC side for higher DC output precision and lower ripple.
5.Achieves wide output voltage range, outstanding accuracy and rapid dynamic response.
6.Supports multiple output operation modes including constant voltage (CV), constant current (CC) and constant power (CP).
