UF Series Buffer Modules

The PULS UF series of buffer modules can seamlessly bridge failures of the DC voltage supply system and can also extend the hold-up time after loss of the AC mains voltage. The minimum hold-up times are 160 ms at 40 A or 200 ms at 20 A and up to several seconds at lower loads. Especially in regions with poor mains quality, the buffer module can help to maintain the supply voltage so process data can be saved and processes can be completed in a controlled manner. Buffer modules are also suitable for applications where a short-term peak current that exceeds the current rating of the power supply unit is required.

The capacitor buffer modules UF40.241 and UF20.241 are supplementary devices which can bridge voltage sags or losses for regulated DC 24 V power supplies. Versions are available for 20 A and 40 A applications.

The products of UF series can easily be added parallel to the load circuit at any given point and work autonomously in the background. They utilize service-free electrolytic capacitors, a more efficient and eco-friendly alternative to lead acid batteries, for storing the energy which allows usage even at ambient temperatures from -25°C up to +70°C. Furthermore, buffer modules can be connected in parallel to increase the output ampacity or hold-up time.
