The PM-5133 series is a touch-type 3-phase smart power meter designed for industrial automation and energy management applications. Equipped with a 3.5” high-resolution color TFT touch screen, users can intuitively monitor power information and control power demand to comply with contracted capacity requirements, supporting carbon inventory and ISO-50001 energy management. The product provides comprehensive power measurement capabilities, including a voltage range of up to 500VAC, clip-on CT (supporting various types with input currents up to 400 A), bi-directional kWh measurement, True RMS measurement, and energy consumption analysis with multiple wiring options. The meter also provides power measurement accuracy better than 0.5% (PF=1). In addition, the PM-5133 series supports Total Harmonic Distortion (THD) measurement, enabling high-precision and visualized energy monitoring. The PM-5133 series also features time-stamped power information logging, 1-hour demand trend display and contracted capacity alerts with relay alarm linkage. It supports the display of up to 32 event and alarm records, helping users effectively predict and manage power demand while enabling flexible system integration and remote monitoring applications.
