• VFD Controlled Loads:
VFD output indicates how the motor
and attached load are operating.
• SCR Controlled Loads:
Acurate measurement of phase

measurement gives faster
response than temperature
measurement.
• Switching Power Supplies and
Electronic Ballasts:
True RMS sensing is the most
accurate way to measure power
supply or ballast input power.
Notes : Installation and maintenance should be done with power supply disconnected.
The operator must have accrediation to install this material.
The users must take care of all protection gurantee against electrical shock.

This transducer must be used in electric/electronic equipment
with respect to applicable standards and safety requirements
in accordance with the following manufacturer's operating
instructions.
Caution, risk of electrical shock
When operating the transducer, certain parts of the module can
carry hazardous voltage (eg. primary busbar, power supply).
Ignoring this warning can lead to injury and/or cause serious
damage.
This transducer is a built-in device, whose conducting parts
must be inaccessible after installation.
A protective housing or additional shield could be used.
Main supply must be able to be disconnected.
