Programmable bi-directional DC power supply

The SM15K Series consists of power supplies with excellent efficiency, stability and flexibility. Thanks to the constant power output, one power supply can cover up to five ranges of traditional power supplies with an rectangular VI-curve.

Standard, the SM15K series can be controlled via the front, web interface or ethernet. This connectivity can be expanded at any time by our interface cards. Furthermore, the Master/slave interface allows parallel operation of up to 60 units to create high power systems that can supply up to 27000A. More about those high power systems can be found here.

 

Bi-directional operation

The SM15K series is standard equipped with regeneration technology: Next to supplying the DUT with power, a SM15K power supply allows the DUT to deliver full power back to the grid. This enables highly efficient and compact test setups for battery, PV and inverter applications.
