23.2. UF20.241 BUFFER MODULE
The UF20.241 buffer module is a supplementary device for DC 24V power supplies. It delivers
power to bridge typical mains failures or extends the hold-up time after the AC power is turned
off.
When the power supply provides a sufficient voltage, the buffer module stores energy in the
integrated electrolytic capacitors. When the mains voltage is lost, the stored energy is released to
the DC-bus in a regulated process.
The buffer module can be added in parallel to the load circuit at any given point and does not
require any control wiring.
One buffer module can deliver 20A additional current and can be added in parallel to increase
the output ampacity or the hold-up time.
23.3. YR40.241 - REDUNDANCY MODULE
The YR40.241 is a dual redundancy module, which can be used to build 1+1 or N+1 redundant
systems.
24/32
f the
(Hiccup Mode).
The device is equipped with two 20A nominal input channels, which are individually decoupled by
utilizing MOSFET technology. The output can be loaded with a nominal 40A continuous current.
Using MOSFETSs instead of diodes reduces heat generation, losses and voltage drop between input
and output. Due to these advantages, the unit is very narrow and only requires 36mm width on the
DIN-rail.
The device does not require an additional auxiliary voltage and is self-powered even in case of a
short circuit across the output.
A feature of this redundancy module is a special circuit, which keeps the losses and temperature
low, even at overload and short circuit conditions up to 65A continuous current.
See chapter 24.6 for wiring information.
23.4. YR40.242 - REDUNDANCY MODULE
The YR40.242 is a dual redundancy module, which can be used to build 1+1 or N+1 redundant
systems.
The device is equipped with two 20A nominal input channels, which are individually decoupled by
utilizing MOSFET technology. The output can be loaded with a nominal 40A continuous current.
Using MOSFETSs instead of diodes reduces heat generation, losses and voltage drop between input
and output. Due to these advantages, the unit is very narrow and only requires 36mm width on the
DIN-rail.
The device does not require an additional auxiliary voltage and is self-powered even in case of a
short circuit across the output. It requires suitable power supplies on the input, where the sum o
continuous short circuit current stays below 26A. This is typically achieved when the power supplies
are featured with an intermittent overload behavior
