The PM-3133 is the most powerful, compact size, cost-effective, advanced Smart Power Meters. The PM-3133 series accesses real-time electric usage for three-phase power measurement. It has high accuracy (<0.5%, PF=1 ), the PM-3000 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 equipment in real time under operation.

The PM-3133series 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 ~ 500 VAC, allowing worldwide compatibility. It can be linked with sirens or lightings for alarm messages with its 2 channels relay outputs. The PM-3133 supports Modbus RTU, Modbus TCP or CANopen protocols for easy integration.
