REGATRON's New Generation of Programmable Regenerative DC Power Supplies Is Now Available

The new G5.RSS series features high control dynamics, an exceptional accuracy, a nominal output voltage of up to 3000 VDC, and a wide current-voltage range with an auto-ranging factor of 3. You get the best value for your investment.

The modular and finely graded G5.RSS series is bidirectional regenerative and can operate in CV, CC, CP, CR, and Ri-Sim control modes. It is universally applicable and therefore suitable for all industrial and scientific applications in laboratories as well as on test benches and production lines. Adjustable filter time constants, optional software, programming and communication interfaces as well as safety functions allow the G5.RSS power supplies to be optimally adapted to the customer application requirements.

Modular and Easily Scalable Systems

The output of an individual power supply is in the range from 0...18 kW to 0...2400+ kW, up to 3000 VDC. The advantageous modularity of REGATRON power supply solutions allows the system to be easily adapted to ever changing test requirements. Not only is it possible to reconfigure between parallel, series, and mixed operation, but also to expand the system with additional power supply units or to split it into smaller units. Therefore, the purchase of a REGATRON power supply is a solid investment for the future.


Adjustable controller settings and the integrated 8-channel digital scope assist the user to easily achieve optimal system behavior. The G5.RSS series offers the possibility to store, edit, and recall any device configuration on board the power supply.
