EA Elektro-Automatik GmbH & Co. KG

EA’s flexible high-power DC supplies and electronic loads are integrated into 19 ” rack power supply or closed cabinet solutions and can be cost-effectively adapted to a wide variety of user requirements, thanks to their modular design and the standardized power and protection modules employed.

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. Further still, the EA power supplies can be conventional or bidirectional, and the loads can be conventional or regenerative for a mixed of source and sink capability. High power density units can be easily paralleled up to 1.92MW in output, with up to 2000 VDC.

The DC rack power supply and electronic load series each feature 5 “TFT touch panel display for intuitive control, setup and programming. The intelligent interface allows you to program and test quickly without the need for extensive manual review.

True Autoranging – Advantages for Test

All EA power supplies provide true autoranging giving full power across a larger operating range to test more devices with just one supply. Autoranging enables the power supply to automatically adapt to higher output voltages when there is a smaller current or handle higher currents when there is a lower voltage. EA’s true autoranging can deliver full power down to 33% of rated output voltage.

• Save budget and space
• No oversizing supply
• One supply tests more
• Versatile for future tests

Regenerative Energy Recovery

The PSB Series DC power supply is bidirectional, meaning it can source (provide) or sink (absorb) current and regenerate that current to the local power grid with up to 96% efficiency. Likewise, the ELR Series DC electronic load is regenerative, with the same energy recovery performance. This makes either solution an environmentally friendly choice on top of minimizing investment and test equipment space.

• Save electricity + costs
• Efficiency approx. 96%
• Quick return on investment
• Environmentally friendly
