DTSY866、DSSY866 Three phase electronic prepaid energy meter (Liquid Display)

Overview

The DTSY866 three-phase intelligent cost controlled energy meter adopts the most advanced application specific integrated circuit design and is manufactured using fully automatic surface mount (SMT) production technology. The circuit design and component selection of the electric energy meter are based on a large environmental tolerance, which can ensure long-term stable operation of the whole machine, high precision, high overload, low power consumption, and high reliability performance. Adopting advanced intelligent IC card technology that meets international standards to achieve prepaid payment, with built-in magnetic holding relay. By controlling the relay to control the on and off of the load, the function of urging users to buy electricity before using it can be achieved.

The product meets all technical requirements of GB/T17215.321-2008 "Level 1 and Level 2 Static AC Active Energy Meters" and GB/T 18460.3-2001 "IC Card Prepaid Electricity Sales System Part 3: Prepaid Energy Meters".

Main Features

• Prepaid function: Users can purchase electricity before using it, and power outages may occur if they owe.
