Three Phase Four Wires Din Rail Energy Meter With MODBUS Protocol DRT-301C-II

l         The DRT-301C-II 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         For connection rate up to 100A. or connection with CT 1.5(6)A; 27 CT Changing-Ratios to choose.

l         Far Infrared and RS485 communication; With communication port comply to MODBUS RTU communication protocol; 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.
