Three Phase Prepaid Energy Meter DDSY2788

Introduction:

The Three Phase Prepaid Energy Meter is a new type of IC card-based prepaid meter that incorporates various functions, including energy metering, load control, and user information management.
Our Energy Meter support a “one household, one card” configuration and feature robust anti-counterfeiting capabilities.
The energy meters manufactured by CNTN Electric feature an energy measurement signal output function.
Our electricity meters support two wiring methods: direct connection or connection via current transformers.
All performance indicators of the electricity meters manufactured by CNTN Electric comply with the full technical requirements for electronic three-phase prepaid electricity meters specified in GB/T 17215.321-2008 *Static AC Active Energy Meters for Classes 1 and 2* and GB/T 18460.3-2001.
