DTSU666 Smart Meter 3-phase direct measurement 80A 3-phase smart meter (direct connection up to 80A) for HYD 3-phase inverters, for monitoring electrical parameters in photovoltaic systems. Real-time display of parameters such as three-phase voltage and current, active and reactive power, frequency, positive energy, reverse energy and much more. All data is shown on an LCD display. Measurements of up to 80A are carried out using current transformers, which are available as a set. The measuring device communicates via an RS485 interface and is designed for mounting on a TH rail.
