Product Detail

SD90 series general type of frequency inverter is based on EH600A, it is based on vector quantization V/F control technology, covering EH600A series all software functions, and use the latest generation of Infineon IGBT module. Product appearance, internal hardware and structure design are more reasonable, so that the machine reliability is higher. SD90 series inverter are widely used in textile, metal, plastic, wood, chemical, ceramics and other ancillary equipment; Heating, water supply, central air conditioning, air compressor and other energy-saving projects.
