DATAKOM DKM-405-S analyser, 96x96mm, THD

The DKM-405 is a low cost precision instrument designed to display various AC parameters in a 3-phase distribution panel. The unit features a 32-bir ARM based microprocessor. Thanks to its sampling rate of 4096s/s it reaches 0.5% precision range. The standard unit is designed for 230/400V network. A different version is available for 120/208V systems. The harmonic analysis is available for up to 31 harmonics. THD values of both voltage and current inputs are available. FEATURES: • True RMS measurements • Total harmonic distortion display • Max demand display • Energy pulse output capability • Optically isolated, configurable digital input • Active-reactive power counters • Hour counter • Voltage transformer ratio for MV applications • Front panel programming • Reduced panel depth • Wide operating temperature range • Sealed front panel (IP54) • Plug-in connection system TECHNICAL SPECIFICATIONS: Power Supply Input: 170 - 275VAC, 50 - 60Hz nominal (+- 10%) Different AC supply voltages available.
