UP-25 Undervoltage Buffer

UP-25 Undervoltage Buffer

The UP-25 provides a short-term power supply of DC-powered devices, which are sensitive to voltage drop, such as control units or CPUs of memory-programmable controllers. It bridges voltage dips (no power failure) that occur, e.g., when starting diesel-aggregates, and provides the needed supply voltage to the connected controllers for the bridging period.

Contrary to traditional battery solutions, the UP-25 is completely maintenance-free. The UP-25 is available in 12 V DC and 24 V DC versions. A version with adjustable output voltage (18 to 26 V) is available on customer request.
