Bidirectional dc power supply

High power bidirectional DC power supply

ACME series high-power bidirectional DC power supply uses high-frequency PWM rectification and bidirectional DCDC conversion technology, as well as FPGA digital control technology, to achieve high-performance DC high-power output. It also has the function of energy feedback to the grid, with a power factor of 0.99 and accuracy of 0.1%. Compared to conventional two-way power supplies, the output voltage range is wider, enabling full range high-precision output.
