Unlock Advanced Testing Capabilities with EA Turnkey DC Power Racks

Integrate and Scale Devices for Comprehensive Testing Solutions

EA Turnkey DC Power Racks: The Future of High Performance Testing

As the world moves towards electrification, the demand for high-performance testing solutions for battery packs, fuel cell stacks, solar systems, and electrolysis systems is on the rise. EA’s Turnkey DC Power Racks offer a customizable solution, allowing you to select and integrate the ideal devices for your specific testing and simulation needs.

EA’s rack systems come in various sizes, including 42U, 38U, 24U, and 15U, and are compatible with 3U, 4U, and 6U devices. You can configure these racks with EA-10000 and EA-10000 Industrial series programmable power supplies, bidirectional power supplies, or regenerative loads. The modular design allows for easy parallel connection of devices to scale system performance. For instance, a 42U rack configured with five 60 kW units can deliver up to 300 kW. For maximum power output reaching 3.84 MW, you can connect up to 64 units across 13 racks.

By offering such flexibility and scalability, EA’s Turnkey DC Power Racks provide a comprehensive solution for a wide range of testing applications, ensuring you can meet the evolving demands of the electrification landscape.

Safe, Reliable, and Efficient

Integrated Safety Features

Standardized Compliance: Each EA modular rack system adheres to the EN 60204-1 safety standard and is optimized for 3-phase 400 V mains connectivity.

Emergency Stop Mechanism: Equipped with a 2-channel emergency stop system, featuring an emergency stop button and rear door contact switches in the 19″ cabinet.

Central Safety Relay: A dedicated safety relay centrally monitors and controls the entire safety system, capable of deactivating the redundant AC contactor when required.

Fuse-Protected Infrastructure: Comprehensive fuse protection safeguards all devices and cabling within the rack system for enhanced operational safety.

True Autoranging Capabilities

The term “True Autoranging” refers to the ability of EA’s programmable DC power supplies to automatically adjust voltage and current outputs, ensuring full power across a broad operational range.

Regenerative Power Efficiency

Boasting an efficiency of over 96%, EA power supplies are designed to feed absorbed energy back into the electrical grid. This feature not only saves costs but also serves as an eco-friendly solution

EA Rack System Equipment Options for Your Applications

Optimized Cooling Solutions

Water-Cooled Options: EA rack systems offer both standard air-cooled and advanced water-cooled versions. The water-cooled system includes pre-installed water distribution, making it ideal for environments where noise reduction and heat dissipation are critical.

Enhanced Network and Supply Safety Features

NS Protection for Regenerative Systems: EA rack systems equipped with regenerative loads like PUB, PSB, PUL, or ELR feature Network and Supply (NS) protection. This module monitors the grid and acts as an emergency stop, enhancing the safety of regenerative systems.

Advanced Insulation Monitoring

Optional Isolation Monitor: EA rack systems can be optionally fitted with a high-quality insulation monitor that enhances safety by monitoring the DC output’s insulation resistance against protective earth.

Increased Safety with DC Contactors

Integrated DC Contactors: These are strategically placed between the DC output of the EA rack system and the Device Under Test (DUT), acting as an emergency stop to prevent unwanted current flow, thereby increasing operational safety.

Efficient Power Parallelization

DC Copper Busbars for Enhanced Performance: These are used to parallelize power by connecting multiple DC outputs within an EA rack system, thereby boosting the system’s overall performance.

Simplified Handling with Control Switch

Control Switch for Easy Operation: EA rack systems equipped with a control switch allow for simplified on/off operations. The switch interacts with the system’s redundant AC contactors and can be secured with a padlock for added safety.

Streamlined Connectivity

19″ Ethernet Switch for Reduced Cabling: A high-quality 19-inch Ethernet switch with 24 ports is integrated into the EA rack system, allowing for multi-channel rack operation via a single external Ethernet interface, thus reducing cabling requirements.
