ICP DAS PM-3133i Isolated 3-phase Smart Power Meter

The PM-3133i Isolated 3-phase Smart Power Meter from ICP DAS gives access to real-time electric usage for three-phase power measurement.

With an accuracy of <0.5% (PF=1) the PM-3133i series can be applied to the low-voltage primary side and/or medium-/high-voltage secondary side, enabling users to obtain energy consumption readings from the monitored equipment in real time under operation. The power meter is equipped with wired clip-on CT (various types, support input current up to 400 A). It operates over a wide input voltage range of 10–600 VAC, which allows worldwide compatibility. Built-in AC isolator protection means total isolation between the AC measurement side and the control side.

Product features include: true RMS power measurements; energy analysis for 3P4W, 3P3W, 1P3W, 1P2W; current measurements up to 400 A with different CT ratio; isolated voltage measurements up to 600 V with clip-on CT for easy installation; supports Modbus RTU protocol; multiple data format.

It is recommended that the CT and reference voltage of the meter be installed on the primary side of the ‘AC Filter’ with an EMI ferrite core to minimise the interference effects of the inverter.
