Three-phase network analyser with a universal input for current transformers that can manage multiple current transducers (with voltage output 0÷333mV or current 1A or 5A and Rogowski probes); available in 3 versions with different measurements option.
The product has a 128x64 65536 colours TFT graphic display to visualise the quantities and settings of the product; the buttons on the side of the display allow the user to scroll through the available menus.
Equipped with Ethernet port, Wi-Fi and RS485 Modbus RTU output, it can be easily integrated into monitoring and acquisition systems. All sizes and functions are configurable Web Server with 3 interface modes Ethernet, Wi-Fi - AP and Wi-Fi - STA or with a third party Modbus master by acting on the dedicated registers.
It complies with class 0.5S (kWh) of EN62053-22 and class 0.5S (kVARh) of EN62053-24 and has an accuracy of ±0.5% RDG. The QC-ENERGY-3T can make TRMS measurements of distorted waveforms (voltage/current) and perform phase shift analysis.
The various outputs are isolated from the inputs (Ethernet, RS485 and the two digital outputs are galvanically isolated from both the power supply and the measurement inputs).
It has two digital contacts (open drain NPN) ) for pulse counting and alarm.
