F for AC/DC input with dual fuse.
E for single fuse input in the Live line.
G for single fuse input in the + line.
f
=
L for low Leakage.
R for reduced Leakage.
T for tiny Leakage. *
Z for EFE400MxD models (Class II).
g
=
Y for Oring FET included.
N for no Oring FET.
h
=
T for inhibit.
E for enable.
i
=
V for vertical output connector or nothing for horizontal output connector.
j
=
Nothing for standard channel 1 output voltage, xD or xPD where D is for units with
programmed negative load regulation, PD is for units with programmed positive load regulation,
x is the voltage of the regulation in 100mVolts and is within the Output Adjustment range
(example, 7D = 0.7V of negative load regulation, 18PD = 1.8V of positive load regulation).
klm
=
Three numbers from 0 to 9 which denotes various output voltage/current settings within the
specified ranges of each output for a particular unit or blank for standard output settings. (may
define non-safety related parameters/feature, e.g. reduced primary current limit, reduced OVP)
* L < 300uA leakage, R < 150uA leakage and T < 75uA leakage.

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:
