Scope of application
The DTSD858 three-phase electronic multifunctional energy meter adopts a dedicated chip for energy measurement, which combines active and reactive power measurement with mature multi rate technology. It is designed and manufactured with digital sampling processing technology and SMT process according to the actual electricity consumption situation in China, and is an internationally advanced energy meter.

The DTSD858 three-phase electronic multifunctional energy meter can measure both positive and negative active and reactive energy, and measure the maximum demand for active, reactive, and various rates. It has 4 rates, 10 time periods, 4 time zones, and 5 daily time period tables, which can record various events such as voltage loss, current loss, demand clearing, programming, and load curve recording. It also has functions such as power testing pulse output, remote control pulse, and clock signal output.
This product can be widely used for comprehensive energy measurement and management in power plants, substations, and various enterprises and institutions, especially suitable for the requirements of multi rate and reactive power measurement put forward by users for electricity transformation.

Its product performance indicators comply with the technical requirements of the national standards GB/T 17215-2002 "Level 1 and Level 2 Static AC Active Energy Meters", GB/T 17882-1999 "Level 2 and Level 3 Static AC Reactive Energy Meters", and DL/T 614-1997 "Multifunctional Energy Meters". The communication protocol complies with DL/T 645-1997 "Multifunctional Energy Meter Communication Protocol" and special protocols required by users.
