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
