- 产品详情
Product overview:
Ws-ads1000 series bi-directional DC power supply has the characteristics of bi-directional 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 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.
Product features:
1) adopt DSP + arm digital control core and full digital control;
2) diode rectification and IGBT chopper two-stage conversion are adopted, with high cost performance and good reliability;
3) power frequency transformer is adopted for isolation, and the output at DC side is completely isolated from the power grid at AC side;
4) wide DC side output voltage range, high precision and fast dynamic response;
5) high dynamic characteristics, 10% - 90% sudden load output response time ≤ 10ms;
6) the energy flows in two directions, and the energy consumption unit can be selected to absorb the energy backwash of the tested product;
7) output has constant voltage and current limiting function;
8) it has the functions of local operation and remote operation;
Application fields:
It is widely used in the early research and development of electric vehicle charging pile and charging pile module, electric vehicle motor and its controller, electric vehicle powertrain system, photovoltaic energy storage system, power operation power supply system, high-power battery charging equipment, high-power switching power supply and various medium and high-power AC / DC systems Later type test, reliability test and delivery test of production line products.
