EA Turnkey DC Power Racks
High-performance cabinet systems for air-/water-cooled supplies
Select devices and integrate into the rack
New high-performance systems are constantly being developed for the electrification of the world. Associated with this is the testing requirement for the battery packs, fuel cell stacks, solar systems or electrolysis systems (or: electrolysers). With the turnkey EA rack system you have the possibility to select the suitable devices for your tests and simulations and to integrate them into the EA turnkey power racks.
Power supplies and loads
Configure 3U, 4U and 6U devices into 42U, 38U and 24U rack systems. Combine EA-10000 and EA-10000 Industrial series programmable power supplies, bidirectional power supplies, or regenerative loads. System performance can be increased by connecting devices in parallel. In a 42U rack with 5 units of 60 kW you can reach 300 kW, for the maximum power of 3.84 MW you can connect up to 64 units in 13 racks.
EA rack systems: A lot of power. Lots of flexibility. Many advantages.

Integrated safety system
Each modular EA rack system includes a safety system integrated as standard. It complies with the EN 60204-1 standard and is prepared for connection to a 3-phase 400 V mains supply. The rack systems are equipped as standard with a 2-channel emergency stop system, including an emergency stop button and door contact switches at the rear door of the 19″ cabinet. A central safety relay monitors and controls the entire safety system and switches off the redundant AC contactor if necessary. In addition, all devices in the rack and the entire cabling of the rack system are protected by fuses.
Sustainable efficiency benefits
Autoranging
“Autoranging” is a term when a programmable DC source automatically offers a wide output range of both voltage and current to maintain full power output across a wide operation range.

Power regeneration
With an efficiency up to over 96%, the absorbed energy is fed back into the grid – Environmentally friendly and cost-saving.

8 Options for EA rack system equipment
Choose the right EA rack system equipment for your applications
01 Water Cooling
In order to be able to use the EA rack systems in as many environments as possible, they are available as air-cooled standard version and as water-cooled version.
Water cooling includes the water-cooled equipment and the pre-installed and tested water distribution system in the rack system, which allows quick and easy connection to the building services.
Choose water cooling for environments where waste heat must not be released to the immediate environment and noise must be reduced.
02 NS Protection
Network and supply protection (NS) increases safety for regenerative systems when EA rack systems are equipped with regenerative loads such as PUB, PSB, PUL or ELR. In the rack system, the NS protection from a well-known supplier monitors the grid for the feed-in of generation and regenerative plants.
The module acts on the emergency stop chain and switches off the entire rack in the event of a mains fault. Islanding (disconnection of the power grid from the connection to the larger power grid) is prevented.
03 Isolation Monitor
The EA rack system is optionally equipped with the insulation monitor of a renowned supplier. This monitors the insulation resistance of the DC output against protective earth. The module acts on the emergency stop chain and switches off the entire rack system in the event of an insulation fault. This increases the safety of the operated system.
04 DC Contactor
DC contactors are used to increase safety and are mounted between the DC output of the EA rack system and the device under test (DUT). In the rack, the DC contactors are integrated into the emergency stop chain. In the event of an emergency stop situation, the DC contactors break the connection between the rack system and the DUT. This provides clear isolation and prevents unwanted currents from flowing between the rack and the DUT.
05 DC Copper bar
DC copper busbars are used to connect the DC output of multiple devices within an EA rack system to parallelize power and increase rack performance accordingly.
A central connection point is provided to connect the DC output of the entire rack to the intended application. The DC copper busbars are supplied pre-assembled and are designed for specific applications.
06 Control Switch
If the EA rack system is equipped with a control switch, the complete rack can be switched on and off with it.
The control switch acts on the redundant AC contactors of the rack system and speeds up or simplifies handling. The control switch can be secured with a padlock.
07 Ethernet Switch
The 19″ Ethernet switch from a renowned supplier with 24 ports is installed in the EA rack system. By using the switch, a multi-channel rack system can be operated via only one external Ethernet interface.
The individual devices are connected internally between the switch and the rack system’s built-in devices. This reduces the number of cables required for the supply in the system and the cabling effort in general.
