• True RMS measurement. • 3 Line 4 Digits ultra bright LED Display . • On site Programmable CT/PT Ratios. • User selectable CT Secondary 1A/5A. • User selectable 3ph3wire / 3ph4wire . • Storage of MIN / MAX values. • Measurement and Display of RPM, Run hours, On hours, No. of interruption. • Optional: MODBUS (RS485) Communication / Pulse output / Analogue output Dimensions in mm - 96 x 96 x 80 User selectable - 3 phase 3 wire / 3 phase 4 wire / Single phase Accuracy - 0.2s TNM3440 measures important electrical parameters and replaces the multiple analog panel meters. It measures electrical parameters like AC current, Voltage, frequency, active energy import and active energy export, Current Demand, kW Demand, kVA Demand and Max Current Demand, Max kW Demand and Max kVA Demand. The instrument has optional output as one pulse output or two pulse output for energy measurement. Product Features On site programmable PT/CT ratios: It is possible to program primary of external potential Transformer (PT), primary of external Current Transformer (CT) on site locally via front panel keys by entering into Programming mode or remotely via MODBUS (RS485) User selectable CT Secondary 5A/1A The secondary of external Current Transformer (CT) can be programmed on site to either 5A or 1A locally via front panel keys by entering into Programming mode or remotely via MODBUS (RS485)
