This is because some circuitry consumes the same amount of power and other circuits become less efficient at reduced power levels The total power consumption of your transmitter can be calculated by using the current and voltage values on the factory test data sheet You may also contact the Harris Field Service Department They can assist in determining the power consumption and efficiency of the transmitter especially at powers other than nameplate Figure 7 is an example of a closed air system s om e HEATED AIR fo u _ EXHAUST AIR B TRANSMITTER CONDITIONED AIR INTAKE AIR a CONDITIONER Figure 7 Closed Air System Another configuration that keeps the transmitter adequately clean and properly ventilated is a positive pressure system In this system outside filtered air is brought into the room using an air intake fan Transmitter exhaust air is removed from the room using a duct hood over the transmitter with an assist fan The exhaust assist fan should be sized about 5 larger than the transmitter CFM specifications The building air intake fan should be sized 10 15 larger than the exhaust helper fan The slight positive pressure in the room will ensure proper transmitter ventilation and will keep dust and dirt from entering the room through small leaks in the building The exhaust duct is best left detached from the transmitter by about six inches similar to a
