Appendix C: Fan Kit Option
IDC controls are designed for convection cooling.The shape and size of our
heatsinks are the result of thermal analysis and experimentation.
All of our controls ha ve built-in temperature protection.Thermal sensors inside the
B8000 controls will activate at a conservative heatsink temperature of 55°C.Thus,
IDC controls will not be damaged when overtemperature conditions occur.
A number of factors affect the internal temperature of a control and whether or
not it needs additional cooling:
• Ambient temperature
• Air flow
• Duty cycle
• Power delivered (the RMS cur rent output)
• Number of axis per control
• Regenerative energy returned from the load
• Bus voltage (B Series)
Adequate ventilation in the enclosure does a lot to cool our controls.Most often, a
single fan in your enclosure or panel will circulate enough air.
When is a Fan Kit Needed?
Here are a few general guidelines to indicate when a fan kit may be necessary for
your high performance application.
B Series Controls:
• With high regenerative loads that do not require an RPACK.
• Vertical,high friction,or clamping applications.
