The PM-3033 series is the most powerful, cost-effective, advanced Smart Power Meters. This series gives you access to real-time electric usage for three-phase power measurement. With its high accuracy (
Direct input from “secondary side 1A/5A” type CTs. Dedicated CTs are no longer needed, lowering the cost of implementation. It operates over a wide input voltages range 10 ~ 500 VAC which allows worldwide compatibility and supports Modbus RTU, Modbus TCP or CANopen protocols for easy integration.
