DDS238-1 ZNSingle phase multifunctional rail mounted electric energy meter（1PType)

Rail type multifunctional electric metermain features

shouldThe electric energy meter is designed with an advanced microcontroller processing system, which has the advantages of simple circuit, high reliability, and high accuracy. The software, hardware, and structural design technology of this product are advanced, with high measurement accuracy. Combined with microcontroller resources, it achievesmeritoriousEnergy metering, measuring current, voltage, power, and power factors, with RS-485 communication function, good anti-interference and anti attack performance, wide working temperature range, and long-term stable and reliable operation. It is currently the smallest energy meter with RS485 communication in the domestic energy meter market. The various error performance indicators of this product comply with the technical requirements of national standards such as GB/T 17215.321-2008 "Level 1 and Level 2 Static AC Active Energy Meters" and DL/T 645-2007 "Communication Protocol for Multi functional Energy Meters" (MODBUS communication protocol can be customized).

This energy meter measures single-phase two-wire active energy,Applicable to the implementation of single rate electricity pricingsecondary circuituserAlternatively, for single-phase electrical equipment with limited space, meter reading can be achieved through RS485 communication networkingIt has the characteristics of good reliability, small size, light weight, beautiful appearance, flexible and convenient installation, etc.
