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;
