Capacitor module MDC90A-0120-50X-..

In the field of energy storage units, the capacitor module is the smallest energy storage unit.

It can be operated directly in the DC link in PowerMode, and has a capacity to store energy. It is used to smoothen short, highly dynamic power peaks, and guarantees the function of peak shaving to a limited extent.

In the event of a power failure, the stored energy can be used to bring the application into a safe state and to shut down the application in a controlled manner.

A single capacitor module with a capacitance of approx. 12 mF can absorb and release energy of approx. 2 kWs in the voltage range between 500 and 800 V of the DC link.

The internal resistance of the device is so low that a power limitation is only defined by the performance of the axis.
