Why Choose the Lovato DMG900T Power Transducer?
The Lovato DMG900T is a high-performance multifunction digital power transducer designed for installation inside electrical switchboards where advanced measurement and communication are required without a front-panel display. It provides comprehensive monitoring of electrical networks while communicating measurement data directly to PLCs, SCADA systems and energy management platforms through integrated serial interfaces.
The DMG900T measures more than 500 electrical parameters, including voltage, current, active power, reactive power, apparent power, frequency, power factor, energy consumption and harmonic distortion. True RMS measurement with continuous gapless sampling delivers highly accurate readings even on installations containing variable speed drives, UPS systems and other non-linear electrical loads.
Unlike the standard DMG900 analyser, the DMG900T is intended for installation within the panel and includes integrated RS232 and RS485 communication ports. It can also be connected to the optional DMG900RD remote display, allowing measurements and configuration to be accessed remotely from the panel door. The modular design supports up to four Lovato EXP expansion modules for additional communication and programmable I/O functions.
