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.

Features
  • Buffering with electrolytic capacitors instead of lead acid batteries
  • Type buffering time of 250ms @ 22VDC/40A
  • Buffer mode selectable by switch: Fixed mode at 22VDC – Dynamic mode for Vin-1 VDC
  • LED indicator for signal status
  • Supports parallel connection to extend buffering time
  • Cooling by free air convection
  • -25~+75°C wide operating temperature
  • 3 years warranty
The DBUF40-24 buffer module is a supplementary device for regulated DC 24V power supplies, which can be used with DIN rail power supplies to provide short term back up for the load.

The DBUF40-24 will enter the buffer mode when the AC mains power is temporarily suspended or interrupted. The buffer function provides stable 24VDC to extend the system operation time, and the buffer time depends on the load current.

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

The DBUF40-24 comes with comprehensive protection features such as over voltage protection, over current protection and short circuit protections. Buffer modules can be connected in parallel to increase the output ampacity or the hold up time.
