(1) @-22ºC, start up with rated power 800W during high voltage (176-280VAC);
(2) @55ºC~65ºC, auto derating of power is recommended. @65ºC, at least 80% rated power will be regularly output for long time;
(3) @55ºC, max output power will be conducted without over-temperature protection. The component
shall normally operate with required strain.
