Ws-evd8000 series bidirectional DC power supply has the characteristics of bidirectional energy flow. It can be used as high-precision DC power supply to supply power to the load or as feedback load to feed back the energy to the power grid. One machine is dual-purpose, reducing equipment investment, saving energy and reducing cost for customers; The whole machine is composed of four quadrant PWM rectifier and DCDC conversion, which can realize two-way energy flow. At the same time, it has many advantages, such as wide voltage range output, high precision, high dynamic response, high AC power factor, low harmonic, etc; Due to the above advantages, the power supply can be used in a variety of industries and applications, either in high-end test occasions or in complex industrial use sites, and can meet the use requirements of the test items in GB / t18488.2-2015s and GB / t29307-2012. It is widely applicable to the early research and development, later type test and reliability test of electric vehicle charging pile and charging pile module, electric vehicle motor and its controller, electric vehicle powertrain system, photovoltaic energy storage system, electric operation power supply system, high-power battery charging equipment, high-power switching power supply and various medium and high-power AC / DC systems, And factory test of production line products.
