High-Power Systems

Advanced systems need advanced power supplies. The SM15K series power supplies are highly valued for their excellent efficiency, stability, and reliability. While keeping its excellent performance characteristics, multiple SM15K units can be combined to get high performance with more power. Ranging up to 27000 A output current at a symmetric and bi-directional constant power curve.

 

Modular Power System

High-power systems can be configured up to 900 kW using the SM15K series with Master/slave interface cards and assembly kits. The advantage of this modular solution is its high flexibility, as systems can be assembled or disassembled in minutes. The master unit can be used to configure the entire setup via front, web interface, or Ethernet. This connectivity can be expanded at any time by our interface cards.

 

Power regeneration technology

Delta's innovative Power Regeneration Technology ensures maximum efficiency, returning full power back into the grid with an impressive efficiency rate, reaching 95%. This eliminates the need for expensive water-cooling systems, resulting in significant cost savings and a smaller carbon footprint. This enables highly efficient and compact test setups for battery, PV, and inverter applications.

 

Flexible Output

With a flexible constant power output characteristic, the SM15K series seamlessly adapts to varying voltage and current requirements. Its constant output power spans the range of three separate power supplies with a traditional rectangular VI-curve, offering unparalleled versatility and value to users.

 

Excellent Performance

Even as a system of multiple SM15K units delivering more power, the system maintains excellent dynamic load response, ensuring high stability and reliability in operation. Consult the data sheet of the SM15K series for more information. Equipped with advanced features such as Ethernet interface, built-in sequencer, PC control software, fine-tune settings, and sink mode, the SM15K series offers comprehensive functionality out of the box. Optional plug-and-play interfaces for master/slave operation, digital I/O, interfaces, or analog programming further enhance usability and customization options. See the data sheets of the SM15K series and Master/ Slave interface for more information.

 

The high power system as an extension to the SM15K series, extends our tradition of delivering power supplies with user high value, low electromagnetic interference, low audible noise, reliability, and efficiency, the SM15K series exemplifies these qualities while offering bi-directional power flow, flexible output, web interface, and plug-and-play interfaces. It stands as an indispensable tool for a wide range of applications, setting a new standard in power supply excellence.
