Description
The PM-3033 series is part of a range of Powerful, cost-effective & advanced Smart Power Meters, that gives you access to real-time electric usage for three-phase power measurement. With its high accuracy (<0.5%, PF=1 ), the PM-3033 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.
Direct input from “secondary side 1A/5A” type CTs. Dedicated CTs are no longer needed, which lowers the cost of implementation. It operates over a wide input voltage range 10 ~ 500 VAC offering maximum compatibility. It also supports Modbus RTU, Modbus TCP or CANopen protocols for easy integration.
Features
- True RMS Power Measurements
- Energy Analysis for 3P4W, 3P3W, 1P3W, 1P2W
- Direct input of secondary side 1A/5A CT
- Voltage Measurements Up to 500 V
- W Accuracy Better than 0.5% (PF=1)
- Supports RS-485, Ethernet (PoE) or CANopen Interface
- Supports Modbus RTU, Modbus TCP or CANopen Protocol
- Total Harmonic Distortion (THD)
- IEC 61010-1 and EN 61010-1
