These Delta VFD-M AC Drives are suitable for both, low-power and high-power applications. Offered AC drives being custom engineered solutions; result in low-volume production, long lead time as well as compared to low voltage drives, higher cost. The designs even have introduced more standard AC drives options, as well as bought latest in high-voltage semiconductor technology which lowered the cost of electronics, still Delta VFD-M AC drives are significantly more expensive and less readily accessible compared to low voltage drives.
