21PRODUCT DESCRIPTION2 Product DescriptionThe COMBIVERT F5-AFE is based on the hardware of COMBIVERT F5 drive convert-ers, which are programmed with a special AFE software. The main application areas areindustrial applications, single-axis applications, test systems and special projects.Features:• Converts a three-phase input voltage into adjustable DC voltage.• Step-up controller for DC link voltage stabilization.• Lower network reactions, harmonic oscillations and commutation notches.• No synchronization unit required.• Single precharging of the DC link via AC input.• Regenerates excess energy from regenerative operation into the supply system.• Replaces braking resistor and braking transistor; thus reduces the heat emission;however optional possible as protection in case of mains power failure.• Supplies single KEB drive converter or after consulting via DC interconnection.• Active power factor correction (PFC) and cos phi control possible.• Internal protection against overcurrent, ground fault and overtemperature.• Appropriate dimensioned DC fuses protect the DC link circuit against short-circuit.Requirements for operation:• AFE / LCL filters.• Symmetric three-wire system with earthed star point.• EMC filter (for observance of EMC standard).• Isolated operation after consulting KEB.• Drive converter without DC link-ground impedance (leakage capacitors).ATTENTION View of an Active-Front-EndThe terminals of an Active Front End unit can be input or output de-pendent on the actual operating status (power supply or regeneration).For the standardization of the view the line side is always regarded asinput and the DC voltage side is always regarded as output.
