The appearance of the fake inverter and the motherboard are exactly the same as those of the real Delta. However, the power consumption of the fake base is low, and MOS tubes are used, which are really all modules.

It can also be verified by multimeter. First, set the multimeter at the "diode" position, and then use the red stylus and black stylus of the multimeter to detect according to the following steps: the black stylus contacts the negative pole P(+) of the DC bus, and the red stylus contacts R, S and T in turn to record the displayed value on the multimeter; Then touch the red stylus of N(-) and the black stylus of R, S and T in turn, and record the display value of the multimeter; If the six displayed values are basically balanced, the frequency converter is true, otherwise it is false.

Delta frequency converter has established a wide brand awareness in the industrial automation market. Each series of products are designed for different operation requirements such as torque, loss, overload and overspeed, and are adjusted according to different industrial machinery properties; It can provide customers with the most diverse choices and is widely used in the field of industrial automation control. It has the characteristics of high power-volume ratio and excellent quality, and can develop special products for different industries.
