How do I specify the required temp differential on anti-condensation heater for an outdoor enclosure for a design ambient temp of -26 to +50 deg C. The only design info I have found is the statement "temp differential between enclosure interior and ambient must be at least +10 degrees to prevent condensation and humidity. Double the size of heater for outdoor applications."
Given the delta T, I can calculate the wattage of the heater. What I need is the method to determine the delta T. Obviously there is a limit as to the max temp the internal components can withstand, so if a delta of 10 degrees is the minimum what is generally accepted as sufficient? (provided components can handle the resulting temp) Is there a standard?
