SPM206 AC Branch Circuit Power Meter

The SPM206 branch circuit power meter offers high-accuracy data monitoring up to class 1.0 (kWh) for one main circuit and 42 branch circuits. It is highly appropriate for data centers because it has a DI module for tracking the status of each branch circuit and a touch screen HMI.
