WebMeter48™ S-Series

The WebMeter48S™ represents the next generation of affordable intelligent metering for your electrical network. The compact module is designed for installations into switchboards, distribution centers, MCCs, or any other UL Listed enclosure. The WebMeter48S™ accommodates up to 48 current transformers in any configuration from 40A-6000A up to 600V. Sampling at over 7KHz (electrical), the WebMeter48S™ delivers accuracy at the circuit-level and reports the information every 3-seconds to the CircuitMonitoring™ system. The WebMeter48S™ is a powerful electrical metering solution allowing for widespread granular monitoring for industrial, commercial, institutional and multi-residential installations. At a dramatically lower cost per circuit and with easy installation, the WebMeter48S™ is designed for economic deployment across a portfolio of facilities while metering down to the individual circuit and equipment level.
