2.2 Environmental requirements

A) Work Environment

Temperature -25℃ to +45℃, humidity 5%-95%.

B) Storage environment temperature

Temperature -40℃ to +80℃, humidity 5%-95%.


2.3. Heat dissipation requirements

A) Power supply cooling

If the power supply is external, the power supply shell itself can meet the heat dissipation requirements. If the power supply is built-in, the heat dissipation must meet the requirement that the temperature rise is less than 35°C under a 25W heat source.

B) Power amplifier heat dissipation

The power amplifier (microwave solid-state source) must meet the requirement that the temperature rise is less than 35°C under an 80W heat source.

C) System cooling

When the ambient temperature is 30°C, the shell temperature of the entire Sunlight simulation source system must be kept below 70°C to meet safety regulations.
