4. Key Specifications

️· Configurable: Measuring items can be freely assigned to output channels.
️· Flexibility: The user can adjust input ranges and lag/lead for reactive power measurement.



To order the meter, you would need to specify the codes for each section of the model code. For example: LSMT21150A1-M would signify:

️· Model: LSMT2-1
️· Voltage Input: 110V AC
️· Current Input: 5A AC
️· DC Output: 4-20mA
️· Pulse/Network Output: Modbus
️· Auxiliary Power Supply: 85-264V AC
