What is a capacitor discharge unit?
This type of device is typically used in high-voltage electrical systems where a sudden surge of current is needed. A capacitor discharge unit, or CDU, can provide this lightning-fast surge of power when it’s needed. A capacitor discharge unit works by rapidly storing energy in its capacitors, then quickly releasing that energy once it’s triggered.
