1 ABOUT THIS MANUAL
This manual provides instructions for the operation and maintenance of the model 5220
Thermoelectric generator.
Correct operation and maintenance according to this manual is critical for proper equipment
function and safety. Keep the following in mind when using these instructions:
Warnings
Throughout this manual you will notice paragraphs preceded by the text “Warning”. It is
imperative that the advice in these paragraphs be adhered to, as failure to do so may result
in personal injury or death and possible damage to the equipment.
Cautions
Throughout this manual you will notice paragraphs preceded by the text “Caution”. It is
imperative that the advice in these paragraphs be adhered to, as failure to do so may result
in damage to the equipment.
Trained Operators
Personnel performing installation, operation, and maintenance work should be properly
trained in such functions.
An operator should be familiar with technical terminology. Terms of significance, defined for
the model 5220, are as follows:
Thermoelectric Generator (TEG): A device that produces electrical power through the
direct conversion of heat energy to electrical energy.
Power Unit (PU): The hermetically sealed portion of the TEG that contains the
thermoelectric materials and cooling fins.
Rated Power: Model 5220 TEG power unit produces 210 Watts when operating in an ambient
temperature of 20ºC (68ºF). With the fuel flow held constant, TEGs operating in ambient
temperatures higher than 24ºC (75ºF) will see power output decline by 0.8 W per ºC (0.44
W per ºF) of temperature change up to a maximum ambient temperature of 65.5ºC (150ºF).
Conversely, for temperatures lower than 20ºC (68ºF) power output will increase by 0.8 W
per ºC (0.44 W per ºF) of temperature change.
Set-up Power: Power produced by the power unit at a specific ambient temperature. It is
derived from voltage across a precision load, also known as V
set
