DTSU866-C/DSSU866-C 7P three-phase four wire electronic energy meter (with press key reset)

Overview

DTS866-C and DSS866-C three-phase active energy meters (hereinafter referred to as instruments) are indoor three-phase energy meters designed and developed by our company to adapt to China's power grid transformation and national conditions. It has high accuracy and feasibility. This instrument adopts internationally advanced ultra-low power large-scale integrated circuit technology and SMT advanced process. The key components are selected from international brands and long-life devices, which improves the reliability of the product and extends its service life. Accurately measure active energy and can read the amount of electricity through infrared communication, making the reading intuitive and easy to use. This instrument design complies with the relevant technical requirements for three-phase static energy meters in standards GB/T 17215.321-2008 (Level 1 and Level 2 Static AC Active Energy Meters), GB/T 17215.323-2008 (Level 2 and Level 3 Static AC Reactive Energy Meters), and DL/T645-1997 (Communication Protocol for Multi functional Energy Meters).

Features

• 1. Energy metering function: metering active positive and reverse energy, and metering reverse energy separately

• 2. Three phase power supply, one or two phases of power outage, measurement accuracy is not affected. After the three-phase power supply is cut off, all stored data will not be lost and can be maintained for more than 10 years.

• 3. It has the function of coupling isolated active and passive pulse test port output (meeting the requirements of remote pulse output, with a pulse width of 80ms ± 20ms).

• 4. Alarm function: When there is a phase loss, the alarm indicator light will turn off.

• 5. Communication function: Communication can be carried out through handheld terminals or PCs to complete programming settings and meter reading. The communication symbol lights up during communication, making it convenient, intuitive, and reliable. Communication protocol Modbus RTU

• 6. Display function: Using a wide temperature and large liquid product display method to show various information; The number of digits displayed for electric energy is 6 for integers and 2 for decimals. Equipped with automatic parameter rotation function, with a rotation time of 5 seconds

• 7. Equipped with zeroing function
