20.1. 1606-XLSBUFFER24 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 module 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 which can
also be used to support peak current demands.
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.
