Mounting Methods
The DBTEC-2A can be mounted in two ways. The first uses a heat sink mounted on the TEC board and uses air cooling from instrument fan. In situations where there is no instrument fan, a small fan can be mounted directly to the TEC board. The second method mounts the TEC onto instrument chassis or large heat sink in instrument. Air flow is highly recommended to keep the heat sink cool.

Method 1
Heat sink mounted on board. Use instrument fan for air cooling.

Method 2
Board is mounted onto instrument chassis or large heat sink.
