Energy Saving + Preventive Maintenance
Providing energy visualization and More!
Introducing the EcoMonitorPlus, an energy measuring units
that visualize "energy" to respond to a wide range of customer needs such
as monitoring of power consumption, configuration of an energy-saving system,
and stable operation of equipment.
The EcoMonitorPlus is suitable if you are thinking
Want to expand the energy-saving
system in phases.
At first, use the EcoMonitorPlus to obtain measurements at locations you are concerned about. Then,
when a need to increase the number of measuring
points arises, add measuring, logging and communication units as needed.
Want to manage data measured at
specific locations easily and use the data
to check energy-saving effects.
The logging unit lets you collect measurement data
via SD memory card. Using the documentation
software, you can easily manage data and create
graphs from data.

Monitoring of leakage current and load current
< Measurement of leakage current >
Features
①Capable of measuring even extremely low levels of leakage current.
Insulation monitor unit (EMU4-LG1-MB)Leakage current resolution: 0.01 mA
⇒Capable of measuring leakage current in equipment groups, such as motors.
②Monitoring of equipment insulation degradation using Ior system
Since leakage current (Io)is affected by the Ioc of the whole equipment,
the Ior measurement is effective for insulation deterioration diagnosis.
■Method of leakage current measurement(Io and Ior measurements)
Specifications
Ioc fluctuates on equipment with long wiring distance
or inverter devices and filters.

Solution
Using the basic unit and extension unit to set the threshold values
for electric leakage and load current, preventive maintenance/
repair can be conducted before an equipment problem occurs so
that unexpected equipment shutdown can be prevented.
