DTSYU866(RF) / DSSYU866(RF) Three phase rail type prepaid energy meter (Non contact/RF card 7P)

Overview

The DTSY866 (RF) and DSSY866 (RF) series electronic three-phase four wire three-phase three wire prepaid electricity meters adopt a shielded and sealed structure, and use a single-chip microcontroller for data acquisition, processing, and storage. Has good resistance to electromagnetic interference, low power consumption, high accuracy, high overload, and long lifespan. Safety complies with all technical requirements for electronic three-phase four wire prepaid electricity meters in GB/T17215-2002, GB/T18460.3-2001, and DL/T645-1997 standards.

Features

Apply computer management to purchase electricity before using it; Can provide load limiting control according to user requirements, one meter one card (one meter multiple cards), dedicated card, no power loss after card loss, and can be reused after card replacement; Electric cards can transmit data bidirectionally; Can automatically alert users to purchase electricity or overload; When the battery level is zero, the power will automatically trip and cut off; Has certain anti-theft software design, etc.
