Bidirectional DC power supply

Product Introduction：

　　The XH-SXZ bidirectional DC test power supply has the characteristic of bidirectional energy flow, which can not only provide electrical energy to the load, but also feedback the electrical energy to the grid without pollution, saving space and cost for users; Supports continuous adjustable voltage range of 24~800V (1000V), current CT1000A (peak 1300A)/power range of 0~500KW (peak 650KW) across the entire range. The power supply can operate in different working modes such as CV/CC/GP to meet the precise testing requirements of different loads. It has complete self diagnosis and protection functions to prevent instrument damage or personal injury caused by misoperation or environmental factors. Suitable for the preliminary research and development, later type testing, reliability testing, and factory testing of products in the fields of electric vehicle motors and their controllers, electric vehicle powertrain systems, etc. Meet the requirements for power supply usage in the testing items of GB/T18488.1-2015, GB/T18488.2-2015, and GBA29307-2012.
