Peak AC Current is the highest peak level of the primary signal that is taken into account for accurate True RMS calculation. Yet the device is designed for maximum continuous True RMS value equal to IPN, whereas the output is limited by the above specified output limitation. 2) According to the UL 508 Standard for Safety for Industrial Control Equipment the primary current must not exceed 475 A.t.RMS through the transducer hole and the supply voltage must not exceed 42VDC.. ●● VFD and SCR waveforms current measurement ●● True RMS output ●● Panel mounting ●● Eliminates insertion loss ●● Isolated plastic case recognized according to UL94-V0 Advantages ●● Large aperture for cable up to Ø32mm ●● High isolation between primary and secondary circuits ●● Easy installation Applications ●● VFD Controlled Loads VFD output indicates how the motor and attached load are operating. ●● SCR Controlled Loads Acurate 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.

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 manufacturers’ operating instructions. Caution! Risk of electrical shock When operating the transducer, certain parts of the module may carry hazardous live voltage (e.g. primary conductor, power supply). The user shall ensure to take all measures necessary to protect against electrical shock. The transducer is a built-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.
