TPM-01 ES Energy Analyzer with 4×4 Digit LED Display

Tense TPM-01 ES Three Phase Digital Energy Analyzer

The Tense TPM-01 ES is an industrial grade, panel mounted digital energy analyzer designed to measure, monitor, and record comprehensive electrical parameters across complex three phase power networks. Outfitted with an expansive, high visibility 4×4 digit LED display matrix, this advanced multimeter provides real time tracking of load variations, grid voltages, line currents, power factors, and consumption variables. Equipped with built in RS485 Modbus RTU communication protocols, the TPM-01 ES acts as an intelligent data terminal, seamlessly transmitting system harmonics and energy metrics to central PLCs or building management networks.

Key Features

High Density 4x4 Digit Display: Designed with a specialized four row, four digit red LED grid that displays simultaneous multi phase values, eliminating the need to manually cycle through screens to view primary line data.
Advanced Harmonic Tracking: Measures and analyzes total voltage and current harmonic distortion (THD-V / THD-I) up to the 31st harmonic, allowing engineers to identify dirty power signatures and protect sensitive components.
Complete Power and Factor Analysis: Tracks per phase metrics including active power ( $P$ ), reactive power ( $Q$ , inductive/capacitive), apparent power ( $S$ ), $cosvarphi$ and true system power factors ( $PF$ ).
Integrated RS485 Modbus Communication: Built with remote communication capabilities using the RS485 interface, facilitating automatic telemetry logging and remote performance reporting.
Comprehensive Parameter Logging: Automatically registers minimum, maximum, average, and peak demand metrics while tracking totalized active import/export energy ( $sum kWh$ ) and reactive energy arrays ( $sum kVArh$ ).
