EA High Power DC Racks — rack DC systems up to 300 kW per rack (up to 3,84 MW)
Country: Germany · Model: High Power DC Racks
High Power DC Racks are assembled into a ready 19″ rack of up to 300 kW DC, and a system of 13 racks reaches 3,84 MW. Voltage goes up to 3000 V and current up to 8000 A per rack, powered from a three-phase 400 V grid. These cabinets are used for battery, inverter and fuel cell benches where a single unit is no longer enough.

Description
The rack is equipped with power supplies, bidirectional power supplies or regenerative loads of the 10000, 10000 Industrial, PSB 20000 and BT 20000 series, so one cabinet can be both a power source and a load. The enclosure height is 42U, 38U, 24U or 15U, and only 42U holds the maximum 300 kW. In the largest configuration 64 units are distributed across 13 racks. The safety system is built in at the factory and includes an emergency stop button, door contacts, a safety relay, a redundant AC contactor and fuses. Water cooling, NS grid protection, insulation monitoring, a DC contactor, copper busbars and an Ethernet switch are added as options. The rack arrives ready to connect: the installer only has to bring in the 3-phase 400 V supply and run the DC busbars to the test object.
How to choose
First, the operating mode is determined, because it defines what goes inside the rack. For one-way supply, power supplies are installed; for charging and discharging with regeneration, PSB 10000 or PUB 10000 units at 30 kW (4U) or 60 kW (6U). The cabinet height is chosen by power, since 300 kW requires 42U, while smaller benches fit in 24U or 15U. For a laboratory desk with a need of up to 1500 W a rack is excessive, and the benchtop PSI 9000 DT is more suitable.
