The buer unit is a supplementary device for regulated

DC48V power supplies. It buers load currents during

typical mains faults and load peaks.

Working principle

In times when the power

supply provides sucient

voltages, the buer unit

stores energy in integrated electrolytic capacitors. In case of

mains voltage fault, this energy is released again in a

regulated process.

Bridges mains faults

without interruption

Statistic show that 80% of

all mains fault lasts less

than 0.2s. These mains

faults are completely bridged by the buer unit. This

increases the reliability of the system as a whole.

Extended hold-up time

Once mains power fails or

is switched o, the buer

unit will continue to

provide the load current

for a dened period of time. Process data can be saved and

processes can be terminated before the DC power switches

o. Controlled restarts are subsequently possible.

Easy to handle, expandable and maintanance-free

The buer unit does not require

any control wiring. It can be

added parallel to the load circuit

at any given point. Buer units

can be switched in parallel to

increase the output ampacity or the hold-up time.
