Product Overview

15kW Bi-directional Programmable DC Power Supplies

With the latest DC bi-directional power supply models, we have extended our capabilities to a higher level of 15kW per unit. A standard feature for these power supplies is the new Power Recovery [Regeneration] Technology: in sink mode they can return full power back into the grid and, thanks to an efficiency of 95%, there is no need for expensive water cooling systems. The flexible output covers the output range of five separate power supplies with a traditional rectangular VI-curve.


  • Operation on wide range of 3 phase AC input voltages
  • Master-Slave operation up to 900kW
  • Large user display, menu-driven operation
  • EMC surpasses CE requirements: low emission and high immunity
  • Low audible noise: temperature controlled cooling fans


  • Ethernet interface, built-in sequencer and web interface
  • Simulation software: Leadless sensing, Internal resistance and Photovoltaic simulation
  • Durable digital encoders for voltage and current adjustment and menu operation

Dimensions and weight:

Width = 19Height = 3 UDepth = 591 mmWeight = 27 kg
