Danfoss VLT Drives' D-Frame VLT Drives

D-Frame VLT drives in 125–450 hp range require less panel or wall space and use back-channel cooling to remove 90% of the heat generated. With IP20, IP21 (NEMA 1) or IP54 (NEMA 12) enclosure ratings, they can be factory-fitted with optional semiconductor fuses, mains disconnect, contactor and circuit breaker.
