Description
The base module of the ELR 21000-80 system takes up 4U and delivers 30 kW at 0–1000 V and 0–80 A. Modules are installed in a rack in 30 kW steps, one rack holds up to 240 kW, and the full configuration reaches 1920 kW. The current slew rate reaches 12 A/µs at 240 kW, so the bench reproduces consumption jumps of server power supplies and 800 V bus converters. The energy absorbed during a test is not turned into heat by the system but returned to the grid with an efficiency of up to 95 %. For a laboratory this means less need for air conditioning and a lower electricity bill during long runs. The total current of up to 5120 A is reached by parallel operation of modules in several racks.
How to choose
The system is scaled to the required power, and each 30 kW adds one more ELR 21000-80 module. For a single-rack bench up to 240 kW is enough, and larger loads need several racks. When a battery has to be tested rather than power electronics, BPTS 20920-720 at 180 kW for packs or BMTS 20200-840-2 with two 60 kW channels for modules is more suitable. Fuel cells are discharged on the FCTS 20920-720 with an efficiency of up to 96,5 %.

FAQ
What power does one ELR 21000 rack have?
Up to 240 kW; the rack is built from 30 kW ELR 21000-80 modules. Several racks together give up to 1920 kW.
What is the current slew rate of ELR 21000?
Up to 12 A/µs at a power of 240 kW. This is enough to simulate dynamic loads on an 800 V DC bus.
Does ELR 21000 return energy to the grid?
Yes, the loads are regenerative and return the absorbed energy to the grid with an efficiency of up to 95 %.
What current and voltage are available in the ELR 21000 system?
Voltage is 0–1000 V and total current is 0–5120 A. A single ELR 21000-80 module works with a current of 0–80 A.
Can I start with one rack and expand the system later?
The design is modular: power changes in 30 kW steps up to 240 kW per rack, and then by adding racks up to 1920 kW.
