EA Programmable DC Electronic Loads
Conventional and regenerative loads
Available in conventional and regenerative, DC electronic loads from EA Elektro-Automatik boast high power density and premium features not found on typical loads. Offering input power ratings up to 15kW in 3U or 30kW in 4U chassis with max 2000 VDC. Easily parallel operation for almost 1.92MW of power. Regenerative ELRs reduce heat, noise and HVAC costs. All of EA’s DC power supplies and DC electronic loads feature true Autoranging which automatically offers increased current at lower voltages. EA’s loads come in desktop, tower-style or 19 “rack-mount.
The EL / R series features 5 “TFT touch panel display for intuitive control, setup and programming. The intelligent interface allows you to configure test routines and program the unit quickly without the need for extensive manual review.
DC electronic loads 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.

ELR Benefits Summary Video
True Autoranging – Advantages for Test
All EA 19” rack mounted electronic loads provide true autoranging giving full power across a larger operating range. Autoranging enables the load 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/load
- One solution tests more
- Versatile for future tests
Regenerative Energy Recovery
The EA ELR load can sink (absorb) current and regenerate that current to the local power grid with up to 96% efficiency. This energy efficiency saves electrical costs and runs significantly cooler, making the ELR a very environmentally-friendly “green” solution on top of minimizing investment and test equipment space.
- Save electricity + costs
- Efficiency approx. 96%
- Quick return on investment
- Environmentally friendly
Built-in Function Generator
A common need for dc power supplies and loads is to deliver the output voltage or current with a pattern other than a straight-line dc signal. EA’s built-in digital function generator includes options for sine, triangle, rectangle, and trapezoid waveforms, as well as custom arbitrary wave forms.
