PRODUCT DESCRIPTION
2 Product Description
The COMBIVERT F5-AIC is based on the hardware of COMBIVERT F5 drive convert-
ers, which are programmed with a special AIC software. The main application areas are
industrial applications, single-axis applications, test systems and special projects.
Features:
• Converts a 3-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-bus connection.
• 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:
• AIC/LCLlter.
• Symmetric three-wire system with earthed star point.
• EMClter(forobservanceofEMCstandard).
• Isolated operation after consulting KEB.
• Drive converter without DC link-ground impedance (leakage capacitors).
NOTICE
View of an Active Infeed Controller
The terminals of an Active Infeed Controller 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 as
input and the DC voltage side is always regarded as output.
