ures.
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 additional curren

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.

The 1606-XLSRED is a dual redundancy module, which includes two
diodes as decoupling devices. It
can be used for various purposes.
The most popular application is to
configure highly reliable and true
redundant power supply systems.
Another interesting application is
the separation of sensitive loads
from non-sensitive loads. This
avoids the distortion of the power
quality for the sensitive loads
which can cause controller fail
