ENERAL ESCRIPTION
The UF40 buffer module is a supplementary device for
regulated DC 24V 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.
