Fourteen Performance Characteristics of Bidirectional DC Power Supplies
1. It has multiple output forms such as constant voltage, constant current, and constant power.
2. Equipped with automatic pressure drop compensation function, automatically compensating for line pressure drop.
3. Using PWM rectification technology, power factor>; 0.99, input harmonic lt; 3%, power greater than 93%.
4. Using high-speed digital control technology, the output accuracy reaches 0.1%.
5. Choose a 7-inch touch screen for operation and a user-friendly human-machine interface.
6. The output parameters and maintenance parameters are programmable and suitable for testing different types of devices.
7. The internal equipment is selected from international brands such as Schneider and Infineon, with high reliability.
8. It has multiple operation interfaces, can complete long-distance operations, is unmanned, and is embedded in a testing system.
9. Adopting modular design, the equipment is easy to maintain in the later stage.
10. Integrated heat dissipation channel design, low temperature rise, high operational reliability, and long service life.
11. Multi level filtering circuit design and electromagnetic interference shielding and absorption measures ensure reliable operation of the equipment.
12. Maintain the built-in AC blocking transformer and LC AC/DC filter in the system, with electrical blocking for input and output; AC circuit breakers have a leakage current maintenance function, effectively preventing electrical safety accidents.
13. By switching between the north and south poles, using IGBT circuit design, and employing a purely digital frequency blocking power supply, the output can mimic various DC voltages.
14. Energy can be fed back to the grid:
Simultaneously possessing both power supply and load characteristics, in addition to the function of high-power DC power supply;
Completing the load function of automatic energy feedback to the power grid has outstanding advantages of energy conservation, consumption reduction, and green environmental protection.
Bidirectional DC power supply is mainly used in the early research and development, later type testing, reliability testing, and product line product factory testing of new energy electric vehicles to drive AC/DC motors and controllers, battery pack energy storage systems, and other fields.
