At present, the power terminal have become a trend in electronic devices, power terminal device itself is gradually increasing, and can carry more power, as the terminal size large, which makes the design process in which power terminal block is used to meet the system requirements for this issue becomes even more complex. Here, Amp experts provide some better options. Power factor is one of the first factors to be considered power-handling capability of the device. Simply read the Handbook does not guarantee access to accurate data. Engineers need to understand product performance data is listed in the manual how to test OK.

In Europe, the device's current rating is determined by monitoring current increases temperature of the metal conductor. When the metal pin temperature of 45 ° c higher than the ambient temperature, surveying staff on the current value of the rated current of the device (or maximum value). Other allowable current value of IEC specifications, it is the most current 80%. And unlike the UL standards will enable the metal temperature 30 ° c higher than the ambient temperature of the conductor current nominal value for the current value of 90% for the device.

We can see that the metal parts of the temperature of the conductor is a very important factor in all applications. More important for industrial equipment. Industrial equipment typically requires working in temperatures up to 80 ° c environment. If the Terminal temperature is higher than the temperature of 30 ° c or 45 ° c, the terminals will exceed 100 ° c of temperature. Depending on the selected device type and nominal value of insulation materials, products must be less than the rated value of current work, so as to ensure that they can work reliably in the desired temperature range. In some cases, suitable for compact packaging materials may not be able to meet the thermal requirements very well, so when used in this type of terminal devices must be significantly less than the rated value of current.
