product details

Product description:

The FRDCL series products are power frequency isolated high-power DC electronic load that operates in constant voltage,constant current, constant resistance and constant power modes. Energy can flow in bidirection. It adopts SiC module technology, which greatly improves the efficiency, power density, thereby reducing product volume.

Features:

It has a wide DC voltage range (20-800VDC),which can be applied in various power supply;

Adopt SiC module technology, the efficiency is as high as 95%, enable high-frequency control and fast dynamic response;

With built-in power frequency transformer,safe and reliable;

Complete protection functions to ensure the safe and stable operation of the system;

Multiple units can be operated in parallel to meet supper high power supply requirement.

Typical application:

Fuel cell DC/DC converter, fuel cell engine testing and production aging;

Charge and discharge test of various types of power batteries;

Automotive driver and motor testing and aging;

Testing and aging of power electronic equipment, etc.
