Kaihong is China manufacturers and suppliers who mainly produces DC Test Power Supply with many years of experience. Dc test power supply is a test power supply developed for motor controller, drive motor and vehicle testing in the new energy automobile industry.
Dc test power supply is a test power supply developed for motor controller, drive motor and vehicle testing in the new energy automobile industry. Using four-quadrant PWM rectification technology and pure digital control technology, it can be applied to motor controller, drive motor product research and development, late type test, reliability test, and product line factory test. Fully meet the national standard "GB-T18488.2-2015- Driving motor system for electric vehicles _ Part 2: Test method"; The application requirements of the test items in GBT 29307-2012 Reliability Test Method of Driving Motor System for Electric Vehicles.
1: With constant voltage, constant current, constant power multiple output modes.
2: With automatic pressure drop compensation function, automatic compensation line pressure drop.
3: Using PWM rectification technology, power factor >0.99, input harmonic <3%, efficiency greater than 93%.
4: Using high speed digital control technology, the output accuracy reaches 0.1%.
5: Adopt 7 inch touch screen operation, friendly man-machine interface.
6: Output parameters, protection parameters are programmable, can be applied to different types of equipment testing.
7: Maintenance system built-in AC isolation transformer +LC AC-DC filtering
8: Energy can be returned to the power grid: it has two characteristics of power supply and load. Besides the performance of high-power DC power supply, it can realize the load function of energy automatic feedback to the power grid, with outstanding advantages of energy saving, consumption reduction and environmental protection.
