NEW Delta Elektronika 15kW to 900kW Regenerative Bi-Directional DC Power Supplies

With the latest bi-directional power supply models; SM500-CP-90, SM1500-CP-30 and the SM70-CP-450. Delta have extended their capabilities for 15kW per unit to 900kW. Standard feature for this supply is Delta’s new Power Recovery (Regeneration) Technology: in sink mode these bi-directional power supplies 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.

Some of the SM15K Series Features/Functionalities include:

  • Bi-Directional power supply with standard 15kW source and sink (parallel operation to 900kW)
  • Flexible output with Constant Power characteristics
  • Power Regeneration Technology: in sink mode the PSU returns the energy back into the grid
  • Easy Master/Slave parallel & series operation up to 300kW
  • Very low heat dissipation. Efficiency is more than 95%. No need for expensive cooling systems
  • Excellent dynamic responses to load changes including all-digital control to adapt regulation to match load type
  • Designed for long life at full power
  • Protected against all overload and short circuit conditions
  • Operation on wide range of 3 phase AC input voltages
  • Ethernet interface, built-in sequencer and web interface are included
  • Large user display, menu driven operations
  • Durable digital encoders for voltage and current adjustment and menu operation
  • EMC surpasses CE requirements; low emission and high immunity
  • Low audible noise; temperature controlled by cooling fans
