The CE1 series intelligent power meters (hereinafter referred to as meters) are designed using microprocessors and AC sampling technology, and can measure various power parameters such as voltage, current, active power, reactive power, apparent power, power factor, frequency, active energy, reactive energy, harmonics, etc. They can be used independently or form a communication network through a standard RS-485 communication port. The product's power parameters are displayed on high-definition digital tubes or large LCD screens, making it more convenient and user-friendly to use.
