342A3648PF20A28C FET-OR Modules
The 342A3648PF20A28C FET-OR module is a redundancy module that can be used to FET-OR and decouple two power
supplies of the same type to increase power or provide redundancy. The FET-OR module provides 100% decoupling of power
supplies connected in parallel. The module is supplied ready for DIN-rail mounting. Refer to the section
for
power supply specifications.
