Thermal Management: Enclosure Cooling Tips

You need to cool down – Heat inside an enclosure can decrease the life expectancy of controlling units such as your PLC, HMI, AC drives and other items. Excessive heat can cause nuisance faults from your electrical and electronic components: for example, overloads tripping unexpectedly. Heat will also change the expected performance of circuit breakers and fuses, which can cause whole ...

Selecting an Enclosure Fan or Air Conditioner

Internal and External sources often cause enclosure internal temperatures to rise above the ratings of the control equipment. Internally, the same items that can be damaged by heat (power supplies, PLC systems, AC drives/inverters, HMI systems, battery back-up systems, servos, etc.)  may also be the source of the heat. Externally, sources of heat that can
