  • Designed for long life at full power.
  • Protected against all overload and short circuit conditions.
  • Operation on wide range of 3 phase AC input voltages
  • Ethernet interface, built-in sequencer and web interface are included
  • Large user display, menu driven operations
  • Durable digital encoders for voltage and current adjustment and menu operation
  • EMC surpasses CE requirements: low emission and high immunity
  • Low audible noise: temperature controlled cooling fans

Flexible Output, Means Better Value.

Delta Elektronika 15K series offers users 15kW of output power, each unit has a wide output voltage and a wide output current that can be set any were within there limits as long as the 15kW is not exceeded.

Bi-Directional Power Flow - Source/Sink

Bi-directional power means the same constant power characteristic in the second quadrant for the full 15kW. It operates like an electronic load too: previously Delta’s power supplies would be equipped with an optional power sink capable of absorbing up to 10% of the total energy which was dissipated via internal heat sinks. Now, the power sink is standard and can sink up to 100% of the power without the need for dissipating lots of energy.

Power Recovery Regeneration Technology

With the new Power Recovery [Regeneration] Technology Delta returns full power back into the grid and the efficiency of 95% avoids the need for expensive water cooling. Compared to traditional electronic loads – where dissipation is 100% – there is a power loss of just 5%. Rooms will be cooler, costs for air conditioning systems will drop significantly and overall, the SM15K series contributes to a smaller carbon footprint.

Extremely Good Dynamic Response to Load Changes

Fast response to load changes has been a challenge for a long time, especially when it comes to changing from positive to negative current and vice versa. Previously, for applications requiring source and sink devices, several solutions were offered such as pre-loads. The full integration of source and sink in one device is a neater and more efficient solution.
