ODULE
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 additional current.
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 YRM2.DIODE is a dual redundancy module, which has two
diodes as decoupling devices
included. 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 failures.
