** Dc input ratings applicable to IEC/EN/UL/CSA60950-1& 62368-1, specific Non-standard versions only.
All ratings apply for ambient temperatures up to 50°C. (See variations and limitations below)
Output Parameters
There are three EFE400M standard models and two non-standard models with various options and output
parameters shown in the tables below.
Standard models:

Output Channel
Channel 1
Fan output
Standby output
Variations and limitations of use for Standard models:
1. Output power de-rated 1% per volt from 100V to 90V input (channel 1 power 360W at 90V input).
2. Maximum ambient 70°C (de-rating output power 2.5% per °C above 50°C).
3. * Can be adjusted at the factory only.
4. Maximum continuous power output 400W (including fan output).
5. † Models with a combination of (i) vertical output connector), (ii) ORing FET and (iii) case with fan, are limited to
400W max at 40°C ambient or 350W at 50°C ambient.
6. ** Peak power for 10 seconds maximum, maximum rms power of 400W:
