i-meter® 45

Multi-Customer or Multi-Load Metering Made Easy!


The i-meter® 45 is a Multi-Customer Metering System. Capable of metering up to 45 single elements the compact design is great for applications where Tenant or Energy Cost allocation is important. The i-meter® 45 provides critical KwH as well as the ability to monitor Volts, Amps, KiloWatts, Power Factor, Frequency and Harmonics (V, I, kW, kVA, PF, Hz, THD (V/I)). The i-meter® 45 Rail option provides both the contractor and the Installer the ability to save time and money.

  • Innovative Metering Solution
