(1) Start up with rated power 1100W during high voltage range (176-280VAC);
(2) @55ºC~65ºC, auto derating of power is recommended.
@65ºC, at least 50% rated power long time output with regulated voltage
(3) @55ºC, maximum power output without over-temperature protection. The components shall work normally and meet the stress requirements
