Lovato DMG900TD048 multifunction digital power transducer with 12, 24 or 48 V DC auxiliary supply, integrated RS232 and RS485 communication, four current channels and harmonic analysis up to the 63rd order.
£1,333.39
The Lovato DMG900TD048 is an advanced multifunction digital power transducer designed for comprehensive monitoring of single-phase and three-phase electrical networks. Installed inside an electrical panel, it measures and processes hundreds of electrical parameters before transmitting the data to PLCs, SCADA systems and energy-management platforms.
The DMG900TD048 measures voltage, current, active power, reactive power, apparent power, frequency, power factor, electrical energy and harmonic distortion using accurate True RMS measurement. Four current channels support phase and neutral-current monitoring, while individual harmonic analysis up to the 63rd harmonic order provides detailed insight into electrical power quality.
This version operates from a nominal 12, 24 or 48 V DC auxiliary supply, making it particularly suitable for battery-backed panels, substations, renewable energy installations and industrial automation systems. Integrated RS232 and RS485 communication ports support direct system integration, while compatibility with the optional Lovato DMG900RD provides a remote touch-screen interface. The DMG900TD048 is listed as out of catalogue, so contact LED Controls to discuss stock availability or a suitable replacement.
The Lovato DMG900TD048 is designed for applications where an electrical measurement instrument must operate from a low-voltage DC control supply. This makes it well suited to battery-backed switchboards, automation panels and utility installations where monitoring must remain operational during interruptions to the main AC supply.
Integrated RS232 and RS485 interfaces allow measurement data to be transferred directly to supervisory systems without a separate communication module. Detailed harmonic, neutral-current and energy measurements support power-quality investigations, predictive maintenance and continuous optimisation of electrical installations.
