Product details
Application scenarios
Ordinary residential community users
High precision is required for energy metering, supporting active power level 1 (± 1%), and generally single-phase meters default to active power level 2
There are requirements for alarm events related to electric energy meters (such as opening the meter, resetting the meter, power outage information, etc.), such as special needs to prevent users from stealing electricity
