Regenerative AC Electronic Load

Discover EL+ vAC

EL+ vAC is a 4Q programmable AC Current Source designed to emulate the electrical behaviour of passive and active devices connected to the grid. In addition, its grid stage as an Active Rectifier produces clean sinusoidal currents with very low harmonic distortion. This cost-efficient solution is specially suitable for testing AC sources, Applications for Industry and Education, Smart grids, Aeronautic, UPS and EV Charging Infrastructure. Its Regenerative and Bidirectional Hardware allows a reduction in the total power and energy needed for the test.

Academic &amp; RCP

The origins of the Cinergia founding team were in a university research and development center, so we understand the specific needs of Academic and Research applications. In addition to our standard catalogue of products, we can adapt to fit your particular requirements.


Safety first

The units integrate a local Emergency. Stop push button and two signals (input + output) to be connected to the laboratory interlock system. Additionally, the digital outputs can be interfaced to safety tower lights.

4.3” Touchscreens

Allows the local parameterization and command of the device, the configuration of the communications link, plots the main signals and enables the local data logging.

Regenerative technology

Thanks to our bidirectional topology, the All-Terrain AC/DC Converter is regenerative, resulting in a reduction of both the consumed energy during the tests and the power required from the electrical installation.

This technology allows us to work in both directions, as power generators or offering a consumption for the realization of all types of tests.
