36V, 26.7A, THREE PHASE INPUT
23.1. ZM2.WALL - WALL MOUNTING BRACKET
This bracket is used to mount specific DIMENSION units onto a flat surface without
utilizing a DIN-Rail.
23.2. YR40.482 - REDUNDANCY MODULE
The YR40.482 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 mosfets instead of diodes reduces the heat generation and the voltage drop between
input and output.
Each power supply needs it own redundancy module, since the current of each power supply
is greater than the max. rating of 20A of one input of the redundancy module. Both inputs
should be connected in parallel.
The YR40.482 does not require an additional auxiliary voltage and is self-powered even in
case of a short circuit across the output.
