Product Description

Product Description

 

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.

Application area

l Electric vehicle motor and controller testing
l Electric vehicle transmission system and powertrain system testing
l Fuel cell testing
l Motor
l Charging station and charging pile test
l Electric drive system test
l Energy storage system converter test
l Charging and discharging tests for capacitors and supercapacitors
l Battery pack and battery pack charge and discharge test
