Ultracapacitor System consists of ultra capacitor, equipment case, iCMS, and other electrical devices. The ultra capacitors are replacing traditional ups system battery to become the power storage device. The usual nominal voltage of ultracapacitor system ranges from 500V to 1500V, which could satisfy most power and energy storage requirement. It can also be custom-made with additional functions such as pre-charge, discharge at maintenance, capacitance balance, monitor&alarm, protection and data transmission, etc. according to customers’ requirements.
