Heat dissipation
The external Ballast resistors can generate a great deal of heat. That's why,
sometimes, depending on the temperature of the installation area, it may be
necessary to evacuate the heat by means of fans.
See an example with data on the temperatures reached in points of the top
of the module and the effect of the fan:
INFORMATION. If a fan is required due the conditions of the location where
the resistor will be installed, remember that FAGOR offers external ballast
resistors with fan.
