All ratings apply for ambient temperatures up to 50°C. From 50 to 70°C the total output power and current
ratings are both derated at 2.5% per deg C.
Output Parameters
There are three NVM175 standard models with various options, and non-standard models with output
parameters shown in the tables below.
Output channel
designation
Channel 1
Standby output
Variations and limitations of use:
1. NVM175 PSUs can output 180W from channel 1 plus 10.4W maximum from the standby output.
2. Component temperatures must be monitored in the end use application as described in the "Cooling For
Unit" section.
3. All ratings apply for ambient temperatures up to 50°C. From 50 to 70°C the total output power and current
ratings are both derated at 2.5% per deg C.
4. NVM1D product has 18 way connector. Maximum storage is 65°C.
Non-Standard Models:
Non- Standard model: X50015# (# can be any letter), (modified NVM1-1T000-S1-K-S-L)
Output Channel
designation
CH1
Standby
Additional Variations and limitations of use for Non-Standard model X50001#
1. Ratings apply for ambient temperatures up to 60°C. From 60 to 65°C the total output power and current
ratings are both derated at 2.5% per deg C.
2. Component temperatures must be monitored in the end use application as described in the "Cooling For
Unit" section.
