The DDZY285C series is an intelligent energy meter launched by State Grid in 2009, which integrates functions such as metering, cost control, alarm, d
Product details
Application scenarios
Ordinary resident usersGeneral industrial and commercial users (implementing non residential electricity prices), such as commercial plazas and externally operated shops
High end users with high requirements for energy measurement accuracy support active power level 1 (± 1%), and single-phase meters generally default to active power level 2
There are requirements for alarm events related to electric energy meters (such as opening the meter cover, resetting the meter, power outage information, etc.), such as preventing users from stealing electricity and other special needs customers
