Danfoss' D-Frame drives feature back-channel cooling to keep electronics cool
Available in a power range from 125-450 HP (90-315kW) Danfoss’ D-Frame drives are designed to require less panel or wall space than previous models. This is intended to reduce installation costs and increase installation flexibility. These drives also leverage back channel cooling to remove 90% of the heat generated by the drive.
The drives are available with IP20, IP21 (NEMA 1) or IP 54 (NEMA 12) enclosure protection ratings. They also come standard with conformal coated printed circuit boards, which together with the optional heat sink access panel, are made to help extend drive lifetime and reliability. The units can be factory-fitted with optional semiconductor fuses. Additional factory-fitted basic input options such as mains disconnect, contactor and circuit breaker, eliminate the need to install these basic options externally. D-Frame drives also use Danfoss’ back-channel cooling concept to keep electronics safely within optimal operation temperatures.
