These panel meters including voltmeters, ammeters, frequencymeteres, multimeters and analyzers (DV, DA, DM, DF, DVF and DKM series) are designed for accurate measurement of the AC RMS voltage, current, frequency, active power, power factor and many other parameters in single and 3 phase systems. Although they are mainly used in electrical panels, these devices can also be integrated in many other applications.
These controllers provide control and protection of screw or piston type air compressors driven by diesel engines and electric motors. The controllers incorporate all functions needed in compressor control panels.
