WOCEN-EVWP

EVWP Series DC Test Power Supply

The EVWP series dc test power supply is specially developed for motor controller and drive motor test in the new energy electric vehicle industry. It is suitable for reliability test and off-line test of electric vehicle motor and its controller, power bearing system of electric vehicle and other products. It has the advantages of fast dynamic response, low output ripple and high efficiency with adopting the technology of soft switch transformation and multistage closed-loop feedback control. The EVWP series has built-in discharge resistance device, which can provide short-term discharge power and effectively absorb feedback shock.
