Regenerative AC Electronic Load

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.
