EA Bidirectional DC Programmable Power Supplies

Conventional and regenerative power supply

The Bidirectional DC power supply with integrated, regenerative electronic load series EA-PSB 9000 and 10000 provides 15kW in 3U or 30kW in 4U chassis with up to 2000 VDC. This series easily parallels supplies for almost 2MW of power. All EA Elektro-Automatik DC power supplies and loads feature true autoranging which automatically offers increased current at lower voltages, enabling a single supply to meet wider test requirements.

The PSB series of bidirectional DC power supply features 5″ TFT touch panel display for intuitive control, setup and programming. The intelligent interface allows you to configure and test quickly without the need for extensive manual review.

EA bidirectional dc power supplies come standard with an arbitrary waveform function generator, swappable digital interface control and built-in test routines for battery test, photovoltaic simulation and MPP tracking, to name a few.

2 Minute PSB Benefits Summary Video

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 is bidirectional, meaning it can source (provide) or sink (absorb) current and regenerate that current to the local power grid with up to 95% efficiency. The built-in electronic load function is regenerative, making the PSB a very green solution on top of minimizing investment and test equipment space.

  • Save electricity + costs
  • Efficiency approx. 95%
  • Quick return on investment
  • Environmentally friendly

Waveform Function Generator

A common need for DC power supplies is to deliver the output voltage or current with a pattern other than a straight-line DC signal. EA’s built-in function generator includes options for sine, triangle, rectangle, and trapezoid waveforms, as well as custom arbitrary wave forms. Additionally, there are configuration tools for ramping, UI and IU tables, and simulations for fuel cells and photovoltaics.
