Part 1 Product overview
1.1 Brief Introduction
COUNTIS M43 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 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(CT).
This meter can be configured to work with a wide range of CTs, giving the unit a wide range of operation.
Built-in interfaces provides pulse and RS485 Modbus RTU outputs. Configuration is password protected.
This unit can be powered from a separate auxiliary (AC or DC) supply. Alternatively it can be powered from
the monitored supply, where appropriate.
1.2 Product characteristics
Measures kWh Kvarh, KW, Kvar, KVA, P, F, PF, Hz, dmd, V, A, THD, etc.
Bi-directional measurement IMP & EXP
Two pulse outputs
RS485 Modbus
Din rail mounting 35mm
1/5A CT connection
Class 0.5S
The Unit can measure and display:
Line voltage and THD% (total harmonic distortion) of all phases
Line Frequency
Currents, Current demands and current THD% of all phases
Power, maximum power demand and power factor
Active energy imported and exported
Reactive energy imported and exported

The unit has password-protected set-up screens for:
Changing password
Supply system selection 1p2w, 3p3w,3p4w
Demand Interval time
Reset for demand measurements
Pulse output duration
Two pulse output indicates real-time energy measurement. An RS485 output allows remote monitoring
from another display or a computer.
1.3 Application
COUNTIS M43 is a multi-functional three phase energy meter, designed for power system, public facilities,
industrial applications and residential power monitoring needs. It can also be used in AC charging piles,
solar photovoltaic and other occasions. Its complete communication function makes it very suitable for
real-time power monitoring systems.
