Sensor Dimmer Module BTU Dissipation
Sensor dimmer efficiency evaluation
The following table provides information on the thermal efficiency of ETC Sensor dimmer racks. All dimmer efficiencies are measured at maximum current (full load). Note that the watt and some BTU figures shown below apply to single dimmers, not dimmer modules and a module often contains more than one dimmer.
Although Sensor dimmers are designed to operate safely in environments with ambient temperatures of up to 104°F (40°C), as with all electronic equipment, keeping the operating environment at cooler temperatures will help improve the service life of the equipment. In order to maximize the efficiency of your dimming system, dimmer room air conditioning should maintain an ambient dimmer room temperature of 68°F (20°C) or less.
IMPORTANT NOTE: When calculating air conditioning requirements, keep in mind that the BTU outputs cited in the table above are maximums. The heat actually dissipated may be less. Factors that influence actual heat dissipation include service ampacity, as well as how the dimmers are used and typical loads.
