Note 1:
Each input can be loaded up to 20A. At currents above 10A, the other input should not be loaded. It is preferable to parallel the two
inputs in order to minimize the power loss in such cases.
Note 2:
Ensure that the continuous output current does not exceed 25A. Check the short-circuit current of the power sources and if the
power source can deliver more than 25A together, use an appropriate fuse on the output.
Note 3:
The redundancy module can be used with input voltages up to 150Vdc with the constraint, that it can be used only as a single input
module at voltages above 60Vdc. Both inputs need to be connected together as shown in Fig. 3-1. Ensure proper means to protect
against touching this voltage.
