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.



Unit Voltage range Current range
SM 70-CP-450 (Bi-directional operation, Constant Power)

0 - 70 V

-450 .. 450 A

SM 500-CP-90 (Bi-directional operation, Constant Power)

0 - 500 V

-90 .. 90 A

SM 1500-CP-30 (Bi-directional operation, Constant Power)

0 - 1500 V

-30 .. 30 A

Features:

    • Bi-directional power supply with standard 15 kW source and sink
    • 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 900kW
    • 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

Functionalities:

    • Operation on wide range of 3 phase AC input voltages
    • Large user display, menu driven operation
    • EMC surpasses CE requirements: low emission and high immunity
    • Low audible noise: temperature controlled cooling fans
 
*Included*
    • Ethernet interface, built-in sequencer and web interface
    • Durable digital encoders for voltage and current adjustment and menu operation
