Preen PEL Series – Regenerative AC Electronic Load

The PEL Series is an AC electronic load with regenerative function. Traditional resistive AC loads transfer the energy to heat which is dissipated. PEL not only transfers energy back to the grid and reduces the energy consumption, but also provides more accurate control and measurement for load simulation. PEL employs the most advanced PWM rectification (active rectification) technology with four-quadrant operation and digital signal processor technology (DSP). It not only can simulate different load characteristics including resistance and inductive type, but also can feed energy back to the grid, which lowers energy consumption and improves carbon dioxide emissions.

Applications: Burn-in tests, production line and laboratory applications to replace the traditional resistive type AC load bank.
