23.5. YR40.245 - REDUNDANCY MODULES
The YR40.245 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 prevents the output wires from touching and
creating a short the load circuit.
The input of the device is decoupled by utilizing MOSFET technology.
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 46mm 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 a suitable power supply on the input, where the
continuous short circuit current stays below 22A. This is typically achieved when the power supply is
featured with an intermittent overload behavior (Hiccup Mode).
See chapter 24.6 for wiring information.
