Can the ATS22 operate at 50 deg C temperatures?
Issue:
Operating temperature range for the Altistart 22
Product Line:
ATS22, Altistart 22
Environment:
All models, all serial numbers.
Cause:
high or low ambient temperatures.
Resolution:
The standard current ratings for the ATS22 is based on an ambient temperature of 40C (104F).
The minimum operating temperature is -10C (14F). The maximum operating temperature is 60C (140F).
When operating above 40C (104F), the softstart needs to be derated by 2.2% for every degree Celsius above 40C (104F).
For example: ATS22D32S6U is 32A rated. For an ambient temperature of 50C (122F), derating is 22% (2.2 x 10). The 32A softstart rating becomes 24.96A (32A x 0.78 = 24.96).
