EA Bidirectional DC Power Supplies
Programmable power supply & regenerative load all in one
The EA-PSB Series bidirectional DC programmable power supply with integrated, regenerative electronic load series provides 15kW in 3U or 30kW in 4U chassis with up to 2000 VDC. This high power series easily parallels supplies up to 1.92MW of racked power. All EA Elektro-Automatik DC power supplies and loads feature true autoranging to cover a wider operating range of voltage and current, while still maintaining full output. This means that a much wider range of test routines can be addressed with a single EA bidirectional DC power supply with autoranging.
The bidirectional PSB has a built-in regenerative load that boasts 96% energy recovery saving operating costs and almost entirely reducing energy dissipated as heat, making the PSB budget friendly as well as environmentally friendly.
The PSB series bidirectional DC power supply features 5″ TFT Gorilla® Glass touchscreen display for intuitive control and programming. The intelligent interface allows you to configure and test quickly. EA bidirectional dc power supplies come standard with an arbitrary waveform function generator, swappable digital interface module and built-in test routines for battery test, fuel cell simulation, photovoltaic simulation with MPP tracking, and more.

True Autoranging – Advantages for Test
All EA bidirectional DC power supplies offer true autoranging which means that the full source and sink power of the devices is available over a wider operating range. The lower the current required in these ranges the higher the voltage available to maintain full power output. This allows a wider range of DUTs to be tested with a single power supply. EA’s autoranging feature provides full power, output as well as input, all the way down to 33% of system voltage and current.
- Save budget and space requirements
- No oversizing supply selection
- One supply tests more requirements
- Futureproof – 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 96% efficiency. The PSB can do this because of the built-in regenerative electronic load. This had the advantage of significantly reducing heat and saving electrical and HVAC costs through operation. Thus the PSB is a very green solution that is good for the environment and has low impact to the working space in terms of heat while reducing overall space requirement (combining a power supply and load into one asset). The EA bidirectional solution is also friendly for your investment ROI!
- Save electricity + HVAC costs
- Efficiency approximately 96%
- Quick return on investment
- Environmentally friendly
Arbitrary Waveform – Function Generator
A common requirement for programmable DC power supplies is to deliver the output voltage or current with a programmed pattern other than a straight-line DC signal. EA’s built-in function generator includes options for various typical waves such as sine, triangle, rectangle, and trapezoid waveforms, as well as custom programmed arbitrary waveforms. Additionally, provided are configuration tools for ramping, UI and IU tables, as well as simulations for fuel cells and photovoltaics with MPP tracking.
