DTS(X)866 / DSS(X)866 Three phase electronic active and reactive power combination meter

Overview

The DTS (X) 866 and DSS (X) 866 series three-phase electronic active and reactive combination 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. Static three-phase active/reactive power combination energy meter can replace two ordinary three-phase energy meters. Using a meter to measure active and reactive energy, the readings are intuitive and easy to use. The product performance characteristics comply with all technical requirements of GB/T 17215.321-2008 "Level 1 and Level 2 Static AC Active Energy Meters" and 17882-1999 "Level 2 and Level 3 Static AC Reactive Energy Meters".

Features

1. Energy metering function: active and reactive energy metering. Three phase power supply, one or two phases of power outage, measurement accuracy is not affected.

2. Output interface: with optocoupler isolation active and reactive passive pulse output interface.

3. Phase loss indication function: Use three light-emitting tubes to indicate whether there is a phase loss. The three light-emitting tubes represent phases A, B, and C. When a phase is missing, the corresponding indicator light will not light up.
