Product Description

EVWR series regenerative DC electronic load is developed with core technologies such as four-quadrant PWM rectification, bidirectional BUCK conversion, and pure digital control. It has the main features of bidirectional energy flow, 100% energy feedback, high precision, rapid transient characteristics, high conversion efficiency, low pollution to the power grid, rich communication interfaces, and powerful protection functions.

It is suitable for the early research and development, later type testing, reliability testing, and factory testing of products on the production line such as on-board DCDC for electric vehicles, on-board DCDC for fuel cell vehicles, hybrid vehicle generators, and DC charging piles.

Application Fields

1. Electric vehicle DCDC
2. Fuel cell vehicle DCDC
3. Hybrid vehicle generator
4. Charging pile


Product Features

1. Energy can be fed back to the power grid: using four-quadrant control technology, energy flows bidirectionally within the full power range, energy saving and high efficiency.

2. It has multiple output modes of constant voltage, constant current, and constant power.

3. Rapid transient response and fast current switching.

4. High-speed digital control technology is adopted, and the output accuracy reaches 0.1%FS.

5. PWM rectification technology is adopted, the power factor is >0.99, the input harmonic is <3%, and the efficiency is greater than 93%.

6. Seven-inch touch screen is adopted, which is convenient for operation and display.

7. It has a variety of communication interfaces, which can realize remote operation, unattended operation and embedded test system.

8. The internal components adopt international brands such as LEM and Infineon, and the equipment has high reliability.

9. Modular design is adopted, and the equipment is easy to maintain in the later stage.

10. The integrated heat dissipation channel design is adopted, with low temperature rise, high operation reliability and long service life.
