Product description
  • The DBUF20-24 buffer module is an accessory for regulated 24V DC power supplies. The buffer module uses maintenance-free electrolytic capacitors for energy storage, thereby eliminating the need for regular maintenance and replacement compared with other batteries, which also have a shorter service life. The DBUF20-24 features comprehensive protection functions such as overvoltage, overcurrent and short-circuit protection, and can be connected in parallel to increase the output current or the backup time.
Application note
  • Buffer time 350 ms at 20 A.
