ICP DAS brings the most powerful, cost-effective, advanced Smart Power Meters PM-3133i series that gives you access to real-time electric usage for three-phase power measurement. With its high accuracy (<0.5%, PF=1 ), the PM-3133i series can be applied to both low voltage primary side and/or medium/high voltage secondary side and enables the users to obtain reliable and accurate energy consumption readings from the monitored equipments in real time under operation. These compact size and cost-effective power meters are equipped with revolutionary wired clip-on CT (various types, support input current up to 400 A). It operates over a wide input voltages range 10 ~ 600 VAC which allows worldwide compatibility. Built-in AC isolator protection, this means total isolation between the AC measurement side and the control side.

  • 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
