EA Turnkey DC Power Racks

High-performance cabinet systems for air-/water-cooled supplies

EA’s turnkey DC power racks and cabinets are comprised of flexible high-power DC supplies and electronic loads integrated into 19” rack or closed cabinet solutions and cost-effectively adapted to a wide variety of user requirements. EA power rack solutions come ready for use and with safety systems that are fully integrated, wired and prepared in compliance with en 60201-1 saving customers a significant amount of engineering and installation time. The power rack systems include individual breakers for each supply or load plus an emergency stop on the cabinet door with door interlocks

The 19 “rack power supply or cabinet system can be designed as pure DC sources, with power supplies, or as pure sinks, with electronic loads. These racks can be built with our highly flexible PSI series true autoranging power supplies that can deliver full power down to 33% of the rated output voltage. Or designed with our ELR series regenerative electronic loads that save power and cost by converting load current back to the local grid at up to 96% efficiency. Finally, the cabinet system can be based on our PSB series bidirectional supplies that combine both of these technologies into a single unit. The racks provide voltage ratings up to 2000 volts and current ratings up to 8000 amps per cabinet and can be easily paralleled up to 1.92MW in total power output.
