Flexible High-Power Systems
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.
Bi-directional operation
A high-power system is standard equipped with regeneration technology: Next to supplying the DUT with power, a high-power system 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.
