Mean Well DBUF40-24 24V 40A DIN Rail Buffer Module

The DBUF40-24 is a DIN rail-mountable buffer module designed to supplement regulated 24 Vdc power supplies. It stores energy in maintenance-free electrolytic capacitors and delivers up to 40 A of hold-up current during supply interruptions. Units can be connected in parallel to increase output current or extend buffer time.
