EA Electronic High Power Density DC Electronic Loads
Conventional and regenerative programmable loads
The EA ELR regenerative DC electronic load from EA Elektro-Automatik boasts high power density and premium features not found on typical loads. The EA ELR is a regenerative load that can sink (absorb) current and recover up to 96% of that current putting it back to the local power grid. Regenerative ELRs reduce heat, noise and HVAC costs making them cost effective and environmentally friendly. Offering input power ratings up to 15kW in 3U or 30kW in 4U form factor with maximum 2000 VDC. ERLs can be easily paralleled in racks to achieve 1.92MW of power.
Additionally, all of EA’s High Power Density ELR DC electronic loads feature true Autoranging which automatically provides increased current at lower voltages, and vice versa, and still maintain full power.
The ELR series DC electronic loads features 5″ TFT Gorilla® Glass touchscreen display for intuitive control and programming. The smart interface enables you to setup and test quickly. EA ELR DC loads come standard with an arbitrary waveform function generator, in-field swappable digital interface module and included test routines for battery test, fuel cell simulation, PV simulation with MPP tracking, and much more.

Regenerative DC Load with Energy Recovery
The EA ELR is a regenerative load that can sink (absorb) current and recover that current putting it back to the local power grid with up to 96% efficiency. This energy recovery efficiency saves both electrical costs and HVAC costs due to significant cooler operation. This makes EA’s ELR a very environmentally-friendly “green” solution and highly cost effective with payback ROI in just a short period depending on daily utilization.
- Save electrical & HVAC costs
- 96% Efficiency for cooler running and savings
- Fast return on investment lets the ELR pay for itself
- Environmentally friendly as well as user friendly
Wider Test Range with True Autoranging
All ELR DC electronic loads offer true autoranging which means that full power is available over a wider operating range. Autoranging power supplies have a more dynamic power profile scaling current up as voltage drops and vice versa. Simply put, autoranging allows you to test more with one device. While many autoranging power supplies start to lose power before dropping to even 50% of their rated output voltage, EA Elektro-Automatik’s true autoranging capability provides full power down to 33% of the rated output voltage.
- Save budget buying one device instead of many
- No over specifying the size load needed
- One test solution for more applications
- Future proof your investment with autoranging flexibility
Function Generator Included
EA’s EL/ELR DC electronic loads have a built-in function generator that includes the ability to create custom programmed arbitrary waveforms, as well as various typical waveform options such as sine, triangle, rectangle, and trapezoid. Additionally, there are configuration tools for sequencing, UI and IU tables, and simulations for fuel cells, perturbation test, and PV solar array simulation with Maximum Power Point Tracking.
