The PM-5133 Series is a family of intelligent three-phase energy meters with touchscreen control, designed for industrial automation, energy monitoring, and power management applications. The devices feature a 3.5-inch color TFT touchscreen display, providing convenient access to electrical network parameters and energy consumption data.
The meters enable real-time monitoring of energy consumption and tracking of contracted demand limit exceedances, making them an effective tool for energy management systems and for meeting the requirements of the ISO 50001 standard, including carbon emissions monitoring and control initiatives.
The PM-5133 Series supports comprehensive measurement of three-phase electrical network parameters, including voltage up to 500 VAC, connection to various types of current transformers with input currents up to 400 A, bidirectional active energy metering, True RMS measurements, and energy consumption analysis for different wiring configurations. Active power measurement accuracy is better than 0.5% at a power factor of PF = 1.
Additionally, the devices support Total Harmonic Distortion (THD) measurement, enabling advanced power quality analysis. For enhanced usability, they provide time-stamped parameter logging, hourly energy consumption trend display, power limit exceedance alarms, and an event and alarm log.
Thanks to the built-in relay outputs and remote monitoring capabilities, the PM-5133 series can be easily integrated into modern supervisory control and automation systems.
