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.

The MLY10.241 is a dual redundancy module, which has two diodes with a common
cathode 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 w
cause controller fail
