Delta High-Power DC System, 15 kW to 900 kW
15 kW - 900 kW
Manufactured by Delta Elektronika · supplied and integrated by Intepro
Bidirectional DC built from 15 kW constant-power modules and stacked to 900 kW, returning absorbed power to the grid instead of burning it in a load bank.
Manufactured by Delta Elektronika B.V. and supplied by Intepro, which is Delta's listed distributor for the United States, Canada and Mexico. Figures are transcribed from Delta's own published pages, retrieved 2026-09-05. Delta revises its documentation often — confirm against the current datasheet before quoting. Delta Elektronika (Netherlands) is not Delta Electronics (deltaww.com, Taiwan); they are unrelated companies.

Capabilities
- Five voltage classes: 0 - 70 V, 0 - 210 V, 0 - 500 V, 0 - 1000 V and 0 - 1500 V
- Every module is 15 kW, and up to 60 parallel gives 900 kW
- Constant power, so the voltage and current maxima are not available together — a unit follows a constant-power curve between them, which is what lets one model cover a wide DUT spread
- Maximum system current runs from 1800 A on the 1500 V class to 27000 A on the 70 V class
- SM500-CP-90 also stacks 6 units in series for 90 kW
- True bidirectional flow, absorbing 100% of power, regenerating to the grid at up to 95% efficiency
- Modules combine with Master/Slave interface cards and output bus bar assembly kits
What it is bought for
Each of these sets out the bus, the clause and where programmes get caught out.

Every figure on this page is transcribed from delta-high-power-system-and-interfaces_deltaelektronika-com_retrieved-2026-09-05.txt. A build gate re-checks each one against that document and fails the build if it is not there.
