ALL MOUNTING BRACKET
This bracket is used to mount specific units onto a flat surface without a
DIN rail.
24.2. 1606-XLSBUFFER48 - B UFFER MODULE
This buffer unit is a supplementary device for DC 24V 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 provides sufficient voltages, the
buffer unit stores energy in integrated
electrolytic capacitors. In case of mains
voltage fault, this energy is released again
in a regulated process. One buffer module can deliver 20A. To buffer the full output current of 40A, two buffer
modules are needed in parallel.

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.
