The ACS 5000 protection scheme responds less than psec, about two hundred times faster than fuses. Highest reliability and efficiency Thanks the combination well-proven com ponents and innovative topology, the ACS 5000 has reliability and efficiency unmatched the market. combines the best two traditional semiconductor technologies: the fast switching the IGBT/IEGT with the proven reliability and low losses the GTO.ACS 5000 Highest performance and lowest cost ownership ABB engineers developed drive that provides advantages over other medium voltage drives reliability, efficiency and power density features that have a direct impact the customer’s cost ownership. Fuseless The converter design does not require any m edium voltage pow fuses, hich are known unreliable, costly and subject to aging. ABB has clearly distinguished itself with this technology com pared unreliable and aintenance­ intensive designs based electrolytic DC-link capacitors. Instead fuses the ACS 5000 uses IGCTs/thyristors, which provide much faster and more reliable protection for the power components. Converter with integrated input transformer ACS 5000 Voltage Source Inverter Multilevel-Fuseless (VSI-MF) topology 4 ACS 5000 ABB . The use IGCTs results low parts count, providing intrinsically less complex, ore efficient and reliable drive. Long-life DC-link capacitors Advanced, self-healing, environmental friendly foil capacitors, designed for long lifetime, are used the DC-link.
