Q-Series
24V, 40A, SINGLE PHASE INPUT
25.3. REDUNDANCY MODULES
YRH80.241 – (2 Inputs each 40A, 1x 80A output)
The redundancy modules in the YRH-series are specially designed for power supplies, which
feature the Hiccup
PLUS
overload behavior.
The YRH80.241 is the preferred redundancy module for the QS40.241 power supply. It is
equipped with two input channels, which are individually decoupled by utilizing mosfet
technology. Using mosfets instead of diodes reduces the heat generation and the voltage
drop between input and output. The YRH80.241 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 46mm width on the
DIN-rail.
YR80.241 – (2 Inputs each 40A, 1x 80A output)
The YR80.241 redundancy module is a unit in the YR-series, that is also suitable in
combination with power supplies, which have a continuous current overload behavior. Size
and performance are the same as of the YRH80.241.
The YR80.241 is more complex than the YRH80 units and therefore are higher in cost.
YRH40.245 – (1x 40A input, 1x 40A output)
The redundancy modules in the YRH-series are specially designed for power supplies, which
feature the Hiccup
PLUS
overload behavior.
The YRH40.245 is a 40A single channel redundancy module, which is equipped with a plug
connector on the output. The plug connector allows replacing the power supply or the
redundancy module while the system is running. The plug connector avoids that the output
wires can touch and short the load circuit.
The YRH40.245 is very slender and only requires 46mm width on the DIN-rail. It also utilizes
mosfet technology instead of diodes for low heat generation and a minimal voltage drop
between input and output. It does not require an additional auxiliary voltage and is self-
powered even in case of a short circuit across the output.
