Earthquake rating	4			Zone
Audible noise		50		dB	Noise is proportional to fan speed, load and ambient temperature.
Testing and working temperature should meet the following three requirements: (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
