Automatic Power Off in Unoccupied Student Dormitory DDEB2S-20D/3X16A Student Dormitory Intelligent Management Control Module

Product Overview:

The DDEB2S-20D/3X16A smart meter is a single-phase electronic energy meter with RS485 interface functionality, enabling long-distance collection of electrical parameters via an RS485 data network. Users can view relevant parameters in the meter through a computer. It can perform metering data collection and on/off control as per commands, supporting one, two, three, or four circuits for metering and control. All parameters and performance indicators fully comply with GB/T17215-2002 "Class 1 and 2 Static AC Active Energy Meters"; DL/T645-1997 "Multifunctional Energy Meter Communication Protocol"; and the technical requirements for electronic single-phase energy meters set by Shaanxi Electric Power Company. The product is well-designed, structurally sound, stable and reliable in operation, with strong anti-interference capabilities.
