Description

The DBUF20-24 buffer module is a complementary device for regulated 24V DC power supplies. The buffer module uses maintenance-free electrolytic capacitors to store energy, eliminating the need for periodic replacement compared to more expensive batteries that also have a shorter lifespan. The DBUF20-24 comes with comprehensive built-in protection features such as overvoltage, overcurrent, and short-circuit protection. Buffer modules can be connected in parallel to increase output capacity or standby time.
