Delta Elektronika SM330-CP-55 Bi-Directional Programmable DC Power Supply
The SM330-CP-55, in the SM6K Series, is a 6 kW family of programmable Source Sink DC power supplies designed for high efficiency, stability, and flexibility. Its constant-power output characteristic significantly extends the usable voltage and current range compared to traditional rectangular-output supplies.
