REGATRON's New Programmable DC Power Supply Series G5.SRC Offers Superior Performance. Best Choice for a Wide Range of Unidirectional Applications.

The new G5.SRC series features high control dynamics, an exceptional accuracy, output voltages up to 3000 VDC, and a wide current-voltage range with an auto-ranging factor of 3.

The modular G5.SRC series consists of finely graded, unidirectional DC power supplies offering full digital CV, CC, CP, and Ri-Sim control modes. The cost-effective, newly developed series is specifically designed for universal use and is therefore well suited for most industrial and scientific applications in laboratories as well as on test benches and production lines. Optional software, programming and communication interfaces, adjustable filter time constants, and, last but not least, standard-compliant safety features enable optimum adaptation to the requirements of customer applications.

Modular and Easy Scalable Systems

G5.SRC power supplies range from 0...18 kW to 0...2000+ kW, up to 3000 VDC. REGATRON's modular concept, which is highly appreciated by users in the field, 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.


The integrated 8-channel digital scope and adjustable controller settings assist the user to easily achieve optimal system behavior. Different system or device configurations can be stored, edited, and recalled on board the power supply.
