teg12vdc- 24air vdc forced air cooling

teg12vdc- 24air vdc forced air cooling
The TEG12VDC -24AIR has a peak rating of 20 watt . The forced air TEG Generator works up to a hot surface temperature
of 400°C (750°F). A pipe vent should be used to allow cooler air to enter the of intake fan to maintain DT (Not Supplied).
The OUTPUT from the TEG is regulated with a Boost/Buck constant voltage/constant current DC to DC converter that
can be adjusted from ~5V to 16V. This is ideal for charge a 5v to 12VDC battery when set at 6.8V to ~14.2V based on
charging specifications found on the battery label.

DO NOT attach to a Battery UNTIL OUTPUT VOLTAGE IS ABOVE 18 VOLTS or DC to DC converter will
not energize!A diode is included to prevent reverse voltage to TEG.
GENERATOR REQUIRES cold air on the fan side for best performance!
We STRONGLY advise a 5” to 6” tube air duct from outside that will draw cold air threw
the fan onto the heat sinks which provides two critical requirements!
1. Creates critical DT that will increase and maintain optimum power generation.
2. Protects the fan from overheating. The fan is rated for 160°F or 70°C maximum.
Do not exceed 750°F hot side temperature on the hot side or you will damage the TEG modules.
The controller is a boost /buck constant voltage/constant current charge controller.
It is set from the factory at 13.8V to 14.2V .
We also recommend charging a battery and drawing loads (lights, motors, etc...) from the battery NOT
from the TEG output directly. Never place the AIR TEG on a cold stove and allow the TEG to heat up with the
stove as both the cold and hot side of the TEG will heat up together and NO DT will be established! Before
applying a load make sure the converter is fully energized. This is done by placing the TEG on a very hot
surface. Waiting for the fan to start then attaching the clamps to the battery.
FAN: 5 inch (120mm) IP55 protection. 3 watt consumption at ideal tested speed or 1.5 watt fan
depending on model!

WHAT IS NOT COVERED: Any damage caused by misuse, abuse, accident (dropping or otherwise
shocking the Generator) normal wear & tear, or physical damage. Also any incidental or consequential damage
or loss is not covered. Improper installation will Null and void all warranty.
There are no warranties of merchantability or of fitness expressed or implied, which extend beyond the
description on the face hereof. In no event shall Thermal Electronics Corp. be liable for damages in excess of
the purchase price. Thermal Electronics Corp. neither assumes nor authorizes any other person to assume for it
any liability in connection with this product.
Abuse, misuse or mistreatment (i.e. if you overheat or drop the Generator) VOIDS all warranties. We do our
best to make all of our Generators as durable as possible. However there is no way for us to fully prevent all
damage due to overheating, or dropping. Warranty is limited to replacement of parts at the full discretion of the
manufacturer and is limited to 1 year from date of purchase.
Example above of a typical installation
It is critical that the surface of the stove already be hot before the TEG is placed on the stove. This is because on
stove start-up of the wood stove the stove warms up slowly not allowing a DT to take hold. Therefore, the entire
TEG heats up cold and hot side together never allowing a Differential between the hot and cold side to be
established. Once heat source is fully engaged then place the TEG air unit so that the hot side heats up rapidly
before the cold side can heat up and the fan will start. Then and only then attach to a battery.

Figure 4
If voltage goes below ~ 8 volts you must reset the DC to DC converter. This can be done by a switch located next to
the relay on the blue aluminum case (Figure 4). The switch is designed to reset the DC converter so it will deenergize. Simply turn the switch off and then on again wait about 1 second between each maneuver. The DC to DC
converter will only operate when there is a minimum of 8VDC loaded and approximately 18V open circuit. The relay
protects the Dc to Dc converter from low voltage.
