Network analyzers (harmonic measurement 2-31, RS-485 communication, 2 relay outputs, 1 digital output)

The TPM-01ESH is a multifunction three-phase power analyzer designed for comprehensive monitoring of electrical systems. Compatible with 3P4W (three-phase with neutral) configurations, it allows for real-time measurement and analysis of key electrical parameters, facilitating energy control and anomaly detection.
This device offers detailed measurements of voltage, current, active, reactive, and apparent power , as well as power factor (PF) and cosφ per phase. It also incorporates voltage and current harmonic analysis up to the 31st order , enabling the evaluation of power grid quality.
The TPM-01ESH includes RS485 Modbus RTU communication , allowing its integration into SCADA or BMS systems. It also features a digital input and two configurable relay outputs , enabling control, alarm, and automation functions based on electrical parameters.
Its high-visibility LED display shows multiple electrical values and system states, including minimums, maximums, averages, and energy demand.
