EL+ ePlus Series High-Frequency Regenerative Electronic Loads

CINERGIA has developed a line of Regenerative Electronic Load products capable of working in a frequency range of 360 to 900Hz. lt was designed to simulate the different loads that can be found in the aircraft.

The testing of aircraft generators with variable frequency is an added difficulty. Since the regulations require a constant value of cos Φ, this implies the need to vary the magnitude of the inductance during the test. Through passive elements, the cost can be very high, and we obtain discrete results.

CINERGIA’s electronics loads are the best tools far this type of tests. Their easy-to-use software al lows us to control all the parameters and adjust the magnitude of the current required in the test. lts Bidirectional and Regenerative Hardware based on a back-to-back power conversion topology also allows energy and power saving.

Thanks to our bi-directional topology, the AC/DC Electronic Load Converter are 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.
