23. ACCESSORIES
23.1. ZM2.WALL - WALL MOUNTING BRACKET
This bracket is used to mount specific
DIMENSION units onto a flat surface without
utilizing a DIN-Rail.
23.2. UF20.241 - BUFFER 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.
