3) The room temperature must be kept under 10°C.
The temperature rises 1°C / 6W / 1m 2 in a metal plate cabinet with a fan provided inside.
This means that the temperature inside of the cabinet rises 1°C when a 6W heating element exists in the cabinet which
has a 1m
2 dissipating surface.
[Example]
When a 200W, 2-axis controller is placed in a cabinet as shown
in the drawing.
When the attachment surface is the back of the cabinet, the
effective dissipating surface is...
0.4 x 0.5 + 0.3 x 0.5 x 2 + 0.3 x 0.4 x 2 = 0.74 m 2
In order to keep the temperature rise within 10°C with this
dissipating surface area, the heat dissipation must be kept under
50.4W as shown below.
60W x 0.74 x 10 = 50.4W
Therefore, 10W must be released for the 200W 2-axis. In this
case, a heat exchanger with a minimum capacity will be able to
release this small amount of heat.

In reality, the Super SEL Controller is not the only source of heat. Other components inside of the control panel must be
taken into consideration.
Note: Using external air for cooling seems to be the easiest method. However, when environmental conditions are not
optimal, small amounts of dust, oil, and metal powder may be sucked into the controller, and can result in electrical
damage to the controller.
