BKF800 digital energy feedback 

Rated voltage: Three phase AC<660V -15%+10%Power range: Below 500KWPower frequency range: 50±3HzCarrier frequency: Depend on the mode(6KHz, 3KHz)DC voltage range: >Power grid voltage 1.5 times+50V,<750V or 1150VPower factor: >98%

Product introduction:BKF800-DF bypass energy feedback, matched with frequency inverter, it takes the excess electric energy to store through the transformer to reuse, or directly feedback to power grid, to ensure the stable of frequency inverter bus voltage. It can be applied to a variety of harsh electromagnetic environment for a long time with out interference and reliable operation, it is applied to various automation systems.

Function features:Restrain harmonic current, improve power energy quality of power grid;Current energy bidirectional flow, four quadrants operation, to improve energy efficiency;The voltage of DC bus is keeping stable, especially fit for the case of supply voltage usually low;Low voltage unit capacity 500KW, no need to parallel connection, reduce fault.

Application:Widely used in down belt, power dynamometer, large centrifugal equipment, lifting equipment.
