● The entire system’s electrical control cabinet is an indoor welded cabinet with an IP40 protection rating.
● The main power supply to the electrical control cabinet is a three-phase, five-wire system with a rated voltage of AC380V, a rated frequency of 50Hz, and a maximum load current of 100A.
● The black wire inside the cabinet is the AC380V power line, the yellow wire is the AC220V control line, the blue wire is the DC24V control line, and the yellow-green line is the ground line.
● The main components inside the cabinet include a molded case circuit breaker, a miniature circuit breaker, an intermediate relay, an AC contactor, a frequency converter, and a PLC.
● The frequency converter inside the cabinet uses the SD100 series, which utilizes the next-generation IGBT module. The product’s appearance, internal hardware, and structural design are more streamlined, resulting in higher overall reliability.
● The cabinet features buttons, indicators, and an advanced operation panel, which connects to the electrical components inside the frequency converter cabinet. This panel displays the operating status of the frequency converter cabinet and also controls the start and stop of the frequency converter.
