ICP DAS introduces the advanced, high-accuracy and cost-effective PM-3133i series, of isolated smart power meters, providing real-time measurements for three-phase power systems. With their high accuracy (<0.5%, PF=1 ), the PM-3133i series can be used on low-voltage primary circuits as well as medium/high-voltage secondary circuits, allowing users to obtain reliable and precise energy consumption data from their equipment during operation. These compact and cost-effective power meters are equipped with innovative wired clip-on CT (available in various types, supporting input current up to 400 A). They operate over a wide input voltages range of 10 to 600 VAC, ensuring compatibility with power systems worldwide.

The PM-3133i-CPS series are isolated 3-phase smart meters that supports CANopen protocol. They provide a CANopen interface that allows users to efficiently collect real-time power consumption data in any CANopen-based applications. By using the CANopen PDO event timer, the meters can automatically transmit measurement data at regular intervals, improving communication efficiency when large volumes of remote power information are required. In addition, the PM-3133i-CPS series feature an arbitration mechanism that avoids data collisions and enhances communication reliability.
