Bidirectional programmable DC power supply use in new energy

Bidirectional programmable DC power supply is a programmable DC power supply integrating DC power supply and regenerative load. The source can be used as a power supply with high precision and fast response, or as a regenerative DC electronic load with rich functions. Used for discharge tests of fuel cell stacks, fuel cell engine systems, power battery packs, supercapacitors, DC power supplies, chargers, etc.

The bidirectional DC programmable power supply can edit and output a variety of waveform power supplies according to the actual usage through the host computer software. The drive motor of the new energy vehicle, and the test of the two-way motor, can simulate the battery input, the input power of the car motor, and the overload response, output current, withstand voltage, and motor efficiency. feedback grid.

Bi-directional programmable DC power supply is a programmable DC power supply that integrates DC power supply and regenerative load. It can be used as a source, realize the source function, and output power to the outside; it can also be used as a load, realize the sink function, absorb power and Clean return to grid; enables standard two-quadrant operation.
