The EA Modular
Power System

Flexible configurable. Minimal footprint.
Best choice for DC high power applications.

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 EA Modular Power System you have the possibility to select the suitable devices for your tests and simulations and to integrate them into a powerful system.

Power supplies and electronic loads

Configure 3U, 4U and 6U devices into 42U, 38U, 24U and 15U racks. Combine EA-10000 and EA-10000 Industrial series bidirectional power supplies, programmable 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 Power systems: A lot of power. Lots of flexibility. Many advantages.

With safety reliable and efficient

Integrated safety system

Each EA Modular Power 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 systems are equipped as standard with a 2-channel fast stop stop system, including a fast stop button and door contact switches at the rear door of the 19″ rack. A central safety relay monitors and controls the entire safety system and
switches off the redundant AC contactor if necessary. In addition, each rack is equipped with a lockable control switch that can be used to turn the power to the devices on and off. All devices in the rack and the entire cabling of the power 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 are feed back into the grid – Environmentally friendly and cost-saving.

7 Options for your EA Power System equipment

Choose the right 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 power 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 fast 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 fast 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 fast stop chain. In the event of a fast 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 are designed for specific applications.

06 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.

07 Signal lamp

The rack is equipped with a signal lamp that is mounted on the roof of the rack. The signal lamp indicates green when the rack is ready for operation (power is present at the rack, AC contactors are open) and red when the rack is in operation (AC contactors closed, voltage may be present at the DC output).
