The EverExceed uXcel Ultra redundancy charger (DC UPS) is a new type charger for batteries. This charging system is made by two independent charging loops in parallel which can carry out the redundancy charge function. This system is controlled by digital intelligence with multi-charging mode, simple operation, and reliability. There is no phase sequence requirement. The transformer is made of high-strength paint copper and it can achieve H grade high temperature resistance and isolation. The power units are made of aluminum profiles and high-power disc-type thyristor units with high performance and reliability.
Available in single and three phases up to 220kW and using ultra-rugged phase-controlled technologies, this series is ideal for all industrial applications including substation battery systems and DC UPS.
