LCD Single Phase Two Wire Din Rail Energy Meter, Model Name/Number: SDM120

Single-Phase Multifunction DIN rail Meter-Measures kWh, Kvarh, KW, Kvar, KVA, PF, Hz, dmd, V, A, etc.Bi-directional measurement IMP & EXPTwo pulse outputsRS485 ModbusDin rail mounting 17.5mm45A direct connectionBetter than Class 1 accuracy ApplicationThe energy-meters "with a blue back-lighted LCD screen for prefect reading" are used to measure single-phase like residential, utility and Industrial application. The unit measures and displays various important electrical parameters, and provide a RS485 communication port for remote reading and monitoring. Bi-directional energy measurement makes the unit a good choice for solar PV energy metering. The compact design and din rail installation provides a easy and economical solution for your metering demand.General SpecificationsVoltage AC (Un) 230VVoltage Range 176~276V ACBase Current (Ib) 5AMax.

Both pulse outputs are passive type.Pulse output 1 is configurable. The pulse output can be set to generate pulses to represent total / import/exportkWh or kVarh.The pulse constant can be set to generate 1 pulse per 0.001(default) /0.01/0.1/1kWh/kVarh.Pulse width 200/100/60msPulse output 2 is non-configurable. It is fixed up with total kWh. The constant is 1000imp/kWh.RS485 output for Modbus RTUThe meter provides a RS485 port for remote communication. Modbus RTU is the protocol applied. For ModbusRTU, the following RS485 communication parameters can be configured from the Set-up menu.Baud rate 1200, 2400, 4800, 9600Parity NONE/EVEN/ODDStop bits1 or 2Modbus Address 1 to 247MechanicsDin rail dimensions 17.5x119x62 (WxHxD) DIN 43880Mounting DIN rail 35mmSealing IP51 (indoor)Material self-extinguishing UL94V-0* FREE 7 DAYS ACQUISITION SOFTWARE LICENSE.
