15kW Bi-directional DC Power Supplies

SM15K series


Programmable bi-directional DC power supply
With our latest DC bi-directional power supply models we have extended our capabilities to a higher level of 15kW per unit. Standard feature for these power supplies is Delta’s 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.
