With the latest Delta DC bi-directional power supply models, new extended capabilities have been expanded to 15 kW per unit. Standard features 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.
