Three Phase Four Wires Din Rail Energy Meter With Multi-tariff DRT-301M

Model: DRT-301M (3P4W, RS485& Far infrared with multi-tariff)
Name: Three Phase Four Wires Din Rail Energy Meter With Multi-tariff DRT-301M

l The DRT-301M is three phase kWh meters with a LCD display in a 7 modules (126mm) casing, ensuring a high accuracy class (Class1), a very low starting current which makes it exceptionally suited for photovoltaic energy systems and general use.

l Excellent long term stability which is designed for DIN, IEN and EN standards and 5 years of warranty.

l MID B&D approval which ensures the meter is produced to the highest European and International standards and the meter legally suited for business and invoicing purposes.

l Far Infrared and RS485 communication; With communication port comply to Modbus RTU &DL/T645 communication protocol option; Communication baud rate can be set 1200(default),2400,4800,9600,19200(option).

l It can measure and monitor all three phase at the same time, including active power, reactive power, max. demand, power factor, voltage, current, frequency, instantaneous power.

l Multi-tariff,4 TOU rates,10 time segments.
