24.1. 1606-XLC Wall Mounting Bracket
This bracket is used to mount specific power supplies onto a flat surface
without a DIN rail.
24.2. 1606-XLSBUFFER48 Buffer Module
This buffer unit is a supplementary device for DC 48V power supplies. It delivers power
to bridge typical mains failures or extends the
hold-up time after turn-off of the AC power.
In times when the power supply provide
sufficient voltages, the buffer unit stores
energy in integrated electrolytic capacitors.
In case of mains voltage fault, this energy is
released again through a regulated process.

The buffer unit does not require any control wiring. It can be added in parallel to the
load circuit at any given point. Buffer units can be added in parallel to increase the
output ampacity or the hold-up time.
