The DKM-401 is a low cost precision instrument designed to display various AC parameters in a 3-phase distribution panel.
The standard unit is designed for 230/400V network. A different version is available for 120/208V systems.
The unit fits into a standard 92x92mm panel opening.
The unit features a 32-bir ARM based microprocessor. Thanks to its sampling rate of 4096s/s it reaches 0.5% precision range.
Due to its economical price, it finds a place in every AC distribution panel.
