Application Summary AI generated

This standard specifies the frequency band allocation, output power limits, and electromagnetic disturbance limits for narrowband power line communication (PLC) equipment operating between 3 kHz and 500 kHz on low-voltage mains (typically 220V/380V AC networks). It is applied in smart grid applications such as meter reading, home automation, and industrial control systems to ensure that PLC signals do not interfere with other electrical devices or radio services. The standard is used by manufacturers and test laboratories for compliance testing and certification of PLC modules and equipment in China.
