1. Overview
DTSY1286E, three-phase four-wire and three-wire electronic prepayment meter
(hereinafter referred to as the power meter), the company is based on the excellent
performance of electronic three-phase active energy meter on, developed with energy
metering and user information management and other functions of energy measurement
products, realized after the first payment of electricity, thereby effectively solve electricity
arrears and stealing phenomenon, and to control and adjust the power load, the power
sector energy measurement and management of modern ideal measuring instruments.
