Notes & Conditions
°C
● The PSU can start in a –10°C
environment. There are no
requirements on its performance.
● When the ambient temperature is
60°C, the PSU can work with half
load.

Non-condensing
m
● When the module does not work,
it can be placed at an altitude of
15,000 m.
● When the altitude ranges from
1800 m to 5000 m, high-
temperature derating applies and
the temperature decreases by 1°C
for each additional 220 m.
kPa
The PSU meets the atmospheric
pressure at an altitude of 4000 m.
kPa
Low atmospheric pressure test at
4000 m (acceptance for the rated
input voltage of 230 V AC)
