PRO DC BUFFER 24V 20A, BUFFER MODULE, 24 V

The Weidmüller PRO DC BUFFER 24V 20A is a capacitor-based buffer module for 24 V DC control circuits, holding the output up for at least 200 ms at 20 A when the supply dips or drops out. It is not a battery UPS: the energy is stored in internal capacitors, so there is no battery to replace and no runtime measured in minutes, only ride-through of brief mains disturbances. Units can be connected in parallel to increase either the output current or the buffer time.
