This device refers to the following standards:
Q/GDW 1354-2013 “Smart Electricity Meter Functional Specifications”.
GB/T 17626.2-1998 Electromagnetic compatibility test and measurement technology – Electrostatic discharge immunity test. GB/T 17626.3-1998 Electromagnetic compatibility test and measurement technology – Radio frequency electromagnetic field radiation immunity test . GB/T 17626.4-1998 Electromagnetic compatibility test and measurement technology – Electrical fast transient pulse group immunity test . GB/T 17626.5-1998 Electromagnetic compatibility test and measurement technology – Surge (impact) immunity test . GB/T 17626.8-1998 Electromagnetic compatibility test and measurement technology – Power frequency magnetic field immunity test .
MODBUS-RTU communication protocol.
Single-phase and three-phase PDU meters are based on the innovative SUM (Sustainable, Upgradable and Maintainable) design concept technology. As a key component of the metered cabinet power distribution unit (PDU), after being installed in the PDU body, it can provide active metering functions . User-set alarm thresholds can issue potential circuit overload warnings through real-time local alarms. Users can configure metered cabinet PDUs via RS485.
