20.3. UF20.241 - B
UFFER MODULE
This buffer unit is a supplementary device for DC 24V power supplies and DC/DC
converter. It delivers power to bridge typical mains failures or extends the hold-up time
after turn-off of the AC or DC power. In times when the DC/DC converter provides
sufficient voltages, the buffer unit stores energy in the integrated electrolytic capacitors.
In case of mains voltage fault, this energy is released again in a regulated process.
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.

ODULE
The YR40.241 redundancy module is equipped with two input channels (20A each), which
are individually decoupled by utilizing MOSFET technology. The output current can go as
high as 40A.
Using MOSFET instead of diodes reduces the heat generation and the voltage drop
between input and output. The YR40.241 does not require an additional auxiliary voltage
and is self-powered even in case of a short circuit across the output.
Due to the low power losses, the unit is very slender and only requires 36mm width on the
DIN-rail.
