Key Points

FAQ

Choose by circuit count and enclosure space: 1P is the narrow body, 2P and 4P have a 72×100mm front face, and the 4P version is direct connection. All share the same accuracy classes.
DL/T645-2007, DL/T645-1997 and MODBUS-RTU are supported over the RS485 interface. An optional 4G module provides cloud upload of the same metering data, and the 1P, 2P and 4P versions share this protocol set.
Active energy accuracy is class B or class C. Billing supports 5 tariffs, 14 time segments and 8 daily tariff tables, covering forward and reverse active energy metering.
Operating temperature is -25℃~+55℃ and altitude is limited to 4000m. The meter mounts on a 35mm DIN rail and must be installed in an enclosure rated IP51 or higher.
Certification is held through a CE / CMA / CNAS accredited laboratory. Price is quoted per form factor and option; Request a quote with the model code and whether 4G is required.
