KW4S Eco-POWER METER
1. Electricity meter that acts like an
industrial component (DIN size: 48×48)
3. Log and track data of integrated electrical
energy usage
Eco-POWER METER is both compact and
inexpensively priced. It is easy to install on your
existing equipment and machinery.
It is easy to load the power usage pulse output into a PLC
or counter.
2. Digitally display integrated electrical
energy and electricity charges
You can digitally display integrated electrical
energy, voltage, current, and electricity charges.
This is handy for managing energy-saving.
4. Centrally manage integrated electrical
energy, voltage, and current
Adopts the RS485 for communication specification.
This allows you to log data (integrated
electrical energy, voltage, and current)
from up to 99 units on a PC and PLC.

●Measurement items
Dedicated CT
Supports 4 types of dedicated CT sensors to
cover wide measuring range
Item
Instantaneous electrical power
Unit
kW
Covers a wide measuring range with support for 4 types of CT
(current transformer: sold separately). Also supports 5 A CT of
secondary current input.

Instantaneous electrical power/
Integrated electrical energy
Hour meter
■ Instantaneous electrical power display is possible in addition
to integrated electrical energy.
■ For all power supplies each phase voltage and current display
are possible.
■ Built-in hour meter function.
■ Ability to display an integrated measured power range of up to
9999.99 MWh.
Precise power surveillance is possible by being able to display
down to two decimal places. Also, the display can be
expanded from a 6-digit to a 9-digit display, making it is
possible to display up to 9999999.99 kW.
Since “Instantaneous electrical power” can be
displayed, you can instantly verify the power
being used at the current time.
Pulse input
Electricity charge (yen/dollar/euro/yuan)
CT is 1/3 the size of our previous models to
save space and install more easily.
Charge display supports four currencies: yen,
dollar, euro, and yuan.
A compact CT (current transformer) is used that is
approximately 1/3 the size of previous models.
Voltage (1-2/2-3)
Load time (ON/OFF)
Since an hour meter function is built in, you can measure the
power-on time that is over or under the control current.
Easily connects to PLC
Count value/Preset value
A counter function is built in. By using this “pulse input”,
surveillance other than the electrical power is possible of the
integrated energy in the air or a gas.
●Communication
An RS485 communications port comes standard. Up to 99 units
can be connected to a PLC (when using our recommended
model).
Using MEWTOCOL as the protocol, it is easy to connect to a
DLU (Web Datalogger Unit).
