Supplementary information:
The temperatures were measured under worst case normal mode defined in 1.2.2.1 and as described in
sub-clause 1.6.2 and at voltages as described above.
With a rated maximum ambient temperature of 45°C, the maximum temperature are calculated as follows:
Winding components providing safety isolation:
- Class B → Tmax = 120°C-10°C = 110°C (10°C decreased by thermocouple method)
Operator touchable surface with maximum temperature rise of: 70°C
For the other non-listed component temperature limit, refer to table 1.5.1.
Test condition:
a. 103.5V/50Hz, rated load.
b. 126.5V/50Hz, rated load.
c. 207V/50Hz, rated load.
d. 253V/50Hz, rated load.
e. 103.5V/50Hz, stand by.
