Abstract
An electronic apparatus includes a housing with a power supply unit that receives external electrical power and supplies it to the apparatus using a power controller. The housing includes a heater; temperature and humidity sensors; and an electronic processor that receives power from the power supply unit and controls functions of the electronic apparatus. Upon startup, the power controller receives data from the temperature and humidity sensors; processes the received temperature and humidity data to indicate a current dew point within the housing; and compares the current dew point with a current location temperature at a location within the housing. If the current location temperature is at or below the current dew point, the heater is activated to raise the temperature within the housing. If the current location temperature is above the current dew point, electrical power supplied from the power supply unit to the electronic processor.
