Wiring method
UEM6 series products have the characteristic of non-polarity wiring, which
can meet different wiring requirements of customers
Derating factor
The derating factor of altitude
When the altitude exceeds 2000m, as the altitude increases, the atmospheric
composition, cooling performance, insulation performance, and air pressure all
change. The product parameters can be corrected according to the following
table.
