3.4.2 Controller Temperature
Depending on the ambient temperature and the placement of the controller additional cooling may be
required (see
). To improve cooling of the controller, place the device into a moving air stream. If
the controller is mounted in a compact area or adjacent to additional heat sources (e.g. a 2
nd
controller)
ensure that there is sufficient ventilation. The below curves are measurements of the controller temperature
at 25
°C
ambient. Equation
shows how to calculate the controller temperature for at other ambient
temperatures based on this curve.
