Introduction
Features
The Strider M3 V2 (Part No.: ME-PM-M3) measures and displays the characteristics of single
phase two wires (1p2w), three phase three wires (3p3w,) and three phase four wires(3p4w)
supplies, including voltage, frequency, current, power ,active and reactive energy, imported
or exported. Energy is measured in terms of kWh, kVArh. Maximum demand current can be
measured over preset periods of up to 60 minutes. In order to measure energy, the unit requires
voltage and current inputs in addition to the supply required to power the product.
ME-PM-M3 supports max. 100A direct connection, saves the cost and avoid the trouble of
connecting external CTs, giving the unit a cost-eective and easy operation. Built-in interfaces
provides pulse and RS485 Modbus RTU outputs. Conguration is password protected.

RS485 Serial–Modbus RTU Pulse output
This uses an improved RS485 serial port with Modbus RTU protocol
to provide a means of remotely monitoring and controlling the Unit.
Set-up screens are provided for setting up the RS485 port.
This provides two pulse outputs that clock up measured active and
reactive energy. The constant of pulse output 2 for active energy is
400imp/kWh (uncongurable), its width is xed at 100ms.
The default constant of congurable pulse output 1 is 400imp/
