This standard applies to general low-voltage electrical appliance power monitors and fieldbus-based power monitors. The monitor can generally detect voltage, current, active power, reactive power, power factor, frequency and other parameters, and can also be equipped with switch input and Switching output realizes certain protection or control functions through switching output. It can be used as a monitoring module in conjunction with low-voltage electrical appliances, so that low-voltage electrical appliances without intelligent control have intelligent control and network control functions. This standard applies to monitors with a reference frequency of 50Hz (or 60Hz). This standard does not apply to:
——terminal voltage exceeding 600V (line-to-line voltage for multi-phase monitors);
——portable monitors. This standard specifies the functions, technical requirements, test methods, inspection rules, etc. of the monitor.
