The DCE and DCZ series multifunctional power meters are high-precision, highly reliable, and cost-effective intelligent distribution instrument products designed for applications such as power monitoring, intelligent control, and measurement assessment in power systems, industrial and mining enterprises, public facilities, and intelligent buildings. This series of instruments adopts high-precision dedicated metering chips and highly reliable MCU design, which can simultaneously measure all commonly used electrical parameters in three-phase power grids. They include three-phase voltage (phase/line), three-phase current, active power, reactive power, power factor, grid frequency, UIPQ demand, and bidirectional energy metering. They have standard energy pulse output and RS485 communication interface, and can choose multiple expansion function modules.

The DCE series is a product with conventional functions, including measurement and metering functions, configured with power pulse output and communication interfaces. The DCZ series adds functions such as DC transmission output, switch input monitoring, relay output, etc. on the basis of conventional functions. The product has four optional external dimensions, with a frame size of 120 × 1
