DBUF40-24 - 24V/40A DIN Rail Type Buffer Module

The DBUF40-24 is a DIN Rail mounted 40A buffer module which can be used with DIN rail power supplies to provide short term back up for the load.



The DBUF40-24 buffer is a supplementary device for regulated DC 24V power supplies. 

The buffer module utilises maintenance free electrolytic capacitors to store energy, thus eliminating the need of periodic replacement as compared to costlier batteries which also have shorter functional life span. 

The DBUF40-24 comes with comprehensive protection features like over voltage, over current and short circuit protections. 

Buffer modules can be connected in parallel to increase the output ampacity or the hold up time.
