Features
Energy saving with AC/DC dual power flow control and corrects power factor up to 99%.
Replaces traditional braking resistor for cost savings, space savings, and energy savings.
PWM control substantially reduces peak of harmonic current wave and forms perfect sine wave current.
IEEE STD.519–1992 standard for harmonic current distortation of less than 5%.
Constant DC bus voltage that is not influenced by mains voltage fluctuation.
Supports multiple DC bus intallation:
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).
