    L86 Dimmer Modules BTU Dissipation

    Heat dissipation in ETC dimmer racks is relatively simple to calculate. Use the following table to calculate either watts per dimmer or BTUs per dimmer, them multiply that number by the number of dimmers in the rack. Note that the watt and BTU figures shown below apply to single dimmer, not dimmer modules. (A module contains more than one dimmer)

    L86-1200
    24 watts/dimmer
    81.888 BTUs/dimmer/hr
    L86-2400
    48 watts/dimmer
    163.776 BTUs/dimmer/hr
    L86-2400HR
    100 watts/dimmer
    341.2 BTUs/dimmer/hr
    L86-6000
    120 watts/dimmer
    409.44 BTUs/dimmer/hr
    L86-6000HR
    250 watts/dimmer
    853 BTUs/dimmer/hr


    We suggest you set air conditioning levels to maintain the temperature in the dimer room at 68 degrees or less. ETC dimmers are designed to operate safely in environments with ambient temperatures of up to 104 degrees but, as with all electronics, keeping things cooler will help improve the service of the equipment.
