How to ensure EMC during full-load monitoring of intelligent low-voltage monitoring units?

Full-load EMC monitoring guarantees testing under the most stringent operating conditions.

Design phase: Select components with stable parameters at high temperatures.

Thermal design: Ensure the performance of filters and protection devices does not degrade at high temperatures.

Testing and verification: Conduct full-load EMC testing in a high-temperature chamber, including conducted emissions, radiated emissions, and immunity.

Pay special attention to the thermal noise changes of the power module and sampling circuit. This ensures stable EMC performance under full-load conditions within a temperature range of -25℃ to +70℃.
