## Delta AFE2000 Active Front End Unit

FEATURES

Incorporating years of experience in AC motor drive development, Delta introduces the innovative AFE2000. This unit is designed for a wide range of applications and it achieves outstanding energy saving results. The AFE2000 does not dissipate excess heat into the air but converts it into reusable power that can be supplied back to the mains. The AFE2000 is yet another Delta product that contributes to improving efficiency and productivity and that fulfills our mission “to provide innovative, clean and efficient energy solutions for a better tomorrow”.

**Outstanding Energy Saving Results**

Controls harmonic distortion to less than 5% and corrects the power factor up to 99%.

As a replacement for traditional brake resistors: A high-watts brake resistor is usually applied to a traditional AC motor drive to absorb the excess regenerative energy generated by motor spinning and frequent braking, and then dissipating the excess energy as heat (see Figure 1).. Using brake resistors as an excess energy solution not only creates additional hardware but also occupies more space. The Delta AFE2000 series provides a new solution: instead of dissipating regenerative energy as heat, it converts regenerative energy into reusable electricity and sends it back to the mains, which reduces total energy consumption. The AFE2000 series is a cost saving and environmentally-friendly product (see Figure 2).
