24. ACCESSORIES

24.1. ZM2.WALL - WALL MOUNTING BRACKET

This bracket is used to mount specific DIMENSION units onto a flat surface without

utilizing a DIN-Rail.

24.2. 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 pow

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 outpu

current of 40A, two buffer modules are needed in parallel.

Load

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.
