Danfoss D-Frame VLT Drives can leverage back channel cooling and can be fitted optionally with semiconductor fuses. Smaller size reduces installation costs and increases flexibility.
Danfoss D-Frame VLT Drives are available in a power range from 125-450 hp (90-315 kW) and up to 68% smaller than previous generation D-Frame drives. This reduces installation costs and increases installation flexibility. These drives also leverage back channel cooling to remove 90% of the heat generated by the drive, reducing up front and ongoing costs and making them an ideal panel building solution, the company said.
The new 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, help to extend drive lifetime and reliability. The new units can be factory-fitted with optional semiconductor fuses to further reduce installation costs. 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 back-channel cooling concept to keep electronics safely within optimal operation temperatures. The big advantage of back-channel cooling is that system installation and operating costs can be dramatically reduced, according to the company.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
