Buffer Modules
Available from stockArticle no.:A104.007
The PULS UF20.481 is a maintenance-free buffer module for 48 V DC systems with a nominal current of 20 A. Its integrated capacitors bridge short voltage interruptions, support temporary peak loads and increase the availability of industrial power systems. The module operates across an input range of 38.4 to 60 V DC and can be connected in parallel to increase buffer time or available current. Equipped with screw terminals for reliable installation.

Description
The UF20 buffer module is a supplementary device for regulated DC 48V power supplies, which can be used for various purposes:
- Deliver DC-power to bridge failures of the DC voltage supply system.
- Extend the hold-up time after loss of the AC power.
- Deliver extra short-term peak current above the current rating of the power supply.
It utilizes service-free electrolytic capacitors for storing the energy which allows usage even at ambient temperatures up to +70°C.
The buffer module does not require any control wiring. It can be added in parallel to the load circuit at any given point.
Buffer modules can be connected in parallel to increase the output ampacity or the hold-up time.
