Marc,
If you're looking for the MTBF for the Powerswitch, a product which
allows you to plug two independent AC lines into a DECHUB 900, then the
numbers are >3 million hours at 25 degrees C and >1 million hours at
50 degrees C. The MTBF for the power supplies which plug into the DH900
are approximately 200K hours at 40 degrees C. In Rich Graham's DH900
product specification, the MTBF numbers are listed for different
combinations of supplies with and without N+1 redundancy.
