Select the correct output version
The output voltages in the series description represent different versions. They do not establish that one supply can be switched between all listed DC voltages. Confirm the exact suffix, current rating and installation dimensions against the supplied unit and matching specification.
Check the AC selector before applying power and leave clearance for the cooling fan. Use the manufacturer’s operating and derating requirements when matching the supply to a cabinet load.
