Applications
●
VFD Controlled Loads:
VFD output indicates how the
motor and attached load are
operating.
●
SCR Controlled Loads:
Accurate measurement of phase
angle fired or burst fired (time
proportioned)
SCRs. Current 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.

Safety and warning notes
In order to guarantee safe operation of the transducer and to be able to make
proper use of all features and functions, please read these instructions thoroughly!
Safe operation can only be guaranteed if the transducer is used for the purpose it
has been designed for and within the limits of the technical specifications.
Ensure you get up-to-date technical information that can be found in the latest
associated datasheet under www.lem.com.
Caution! Risk of danger
Ignoring the warnings can lead to serious injury and/or cause damage!
The electric measuring transducer may only be installed and put into
operation by qualified personnel that have received an appropriate
training.
The corresponding national regulations shall be observed during
installation and operation of the transducer and any electrical conductor.
The transducer shall be used in electric/electronic equipment with respect
to applicable standards and safety requirements and in accordance with all
the related systems and components manufacturer’ operating instructions.
Caution, Risk of electrical shock
When operating the transducer, certain parts of the module may carry
hazardous live voltage (eg. primary conductor, power supply).
The user shall ensure to take all measures necessary to protect against
electical shock. The transducer is a build-in device containing conducting
parts that shall not be accessible after installation.
A protective enclosure or additional insulation barrier may be necessary.
The transducer shall not be put into operation if the jaw opening is open
(split core version) or the installation is not completed.
Installation and maintenance shall be done with the main power supply
disconnected except if there are no hazardous live parts in or in close
proximity to the system and if the applicable national regulations are fully
observed.
Safe and trouble-free operation of this transducer can only be guaranteed if transport,
storage and installation are carried out correctly and operation and maintenance are
carried out with care.
