QS40.244

Q-Series

The YR80.242 is equipped with two input channels (40A each), which are individually

decoupled by utilizing mosfet technology. The output current can go as high as 80A. Using

mosfets instead of diodes reduces the heat generation and the voltage drop between input

and output. The YR80.242 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.

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 avoids that the output

wires can touch and short the load circuit.

The YR40.245 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.
