RADS High Precision DC Current Source

RADS series high-precision DC current source is the second generation of low-voltage DC high-current source of our company. It has the characteristics of digital control, high precision, high stability, and output can be reversed. A series of advantages such as cooling and heat dissipation and high reliability. It provides a maximum output current exceeding ±1500A in a standard 5U chassis, and multiple chassis can be directly connected in parallel to provide a current of more than 10000A.

patented design of RADS High Precision DC Current Source

The RADS series high precision DC current source adopts a fully modular design, which maximizes the current output in a small volume, and improves flexibility and reliability. There are up to 6 built-in parallel output current sub-boards with nominal output of 250A. And each of the modular sub-boards can operate independently, so the damaged sub-board will not impact the operation of the overall system, and this feature also allows our customers to configure the suitable number of boards for their needs. 

The inside of the current source is controlled by the “current source controller”, including “LCD display”, “keyboard”, “USB interface”, “fan” and other modules, which can realize cooling fan speed adjustment, LCD display interface control, keyboard control and USB serial port Control, LABVIEW control and other functions, real-time monitoring of current source temperature and output voltage through the signal acquisition module.

Precision DC Current Source working principle

Further more, multi- RADS precision DC current source units can also be connected in parallel to expand their overall output up to 10kA.
