Multifunction Power Analyser
MerCs Strider M73
2. Description
The multifunction energy analyzer Strider M73 is a top new-generation intelligent panel meter, used not only in the electricity transmission and
power distribution systems, but also in the power consumption measurement and analysis.
This document provides operating, maintenance and installation instructions for the MerCs Strider M73. The unit measures and displays the char-
acteristics of 1p2w, 3p4w and 3p3w supplies, including voltage, frequency, current, power and active and reactive energy, imported or exported,
Harmonic, Power factor, Max. Demand etc. Energy is measured in terms of kWh, kVArh and kVAh. Maximum demand current can be measured over
preset periods of up to 60minutes.
In order to measure energy, the unit requires voltage and current inputs in addition to the supply required to power the product. The requisite
current input(s) are obtained via current transformers. The Strider M73 can be configured to work with a wide range of CTs, giving the unit a wide
range of operation. Built-in interfaces provides RS485 Modbus RTU and Ethernet TCP/IP communication.
The unit uses plug-in terminals for easy wiring and push-in mechanism for quick installation.
