The master/ slave interface card enables the SM15K series power supplies, to form a single high-power system by operating in either parallel or series. Additional to the interface card, assembly kits are separately offered to connect the outputs of the units. Both interface and assembly kits are easily installed and exchanged to connect a different number of units in parallel or series.
