Insulated plastic case recognized
according to UL94-V0.
Advantages
High isolation between primary and
secondary circuits
Eliminates insertion loss
Easy installation.
Applications
AC power supplies or Motors:
True RMS current sensing - the most
accurate way to monitor power supply
or motor input power
VFD Controlled Loads:
VFD output current monitoring to
indicate how the motor and the
attached load are operating
SCRs or Switch-mode Rectifiers:
Accurate measurement of output
current
Note :
1) The max. peak AC current is the highest peak level of the primary signal that is
taken into account for accurate True r.m.s. calculation.
Yet the device is designed for maximum continuous true r.m.s. value equal to IPN,
whereas the output is limited by the above specified output limitation.
Renewable Energy Installations or
Backup Batteries:
Continuous condition minitoring
allowing automatic failure detection/
anticipation.

Safety
This transducer must be used in electric/electronic equipment with respect to
applicable standards and safety requirements in accordance with the
manufacturer’s operating instructions.
Installation and maintenance should be done with main power supply
disconnected.
The operator must have an accreditation to install this material.
Caution! Risk of electrical shock
When operating the transducer, certain parts of the module can carry hazardous
voltage (e.g. primary conductor, power supply).
Ignoring this warning can lead to injury and/or cause serious damage.
The user must take care of all protection guarantee against electrical shock.
This transducer is a built-in device, whose conducting parts must be inaccessible
after installation. A protective housing or additional shield could be used.

Remarks
The return busbar and primary conductor elbow must be
located at a minimum distance of 2.5 x the window length
away from the transducer case.
The temperature of the primary busbar can not exceed
90°C.
Dynamic performances are the best with a primary busbar
completely filling the primary aperture.
This is a standard model. For different versions (supply
voltages, different outputs, bidirectional measurements...),
please contact us.
