Low power VLT micro variable frequency drives
Danfoss Drives’ VLT Micro Drive is now available in an M4 frame size covering the three-phase 380 – 480 VAC, 15 – 20 HP range. The M4 is just 250mm tall (292mm with flange) x 125mm wide x 241mm deep. They feature conformal coated PCBs per IEC 60721-3-3, class 3C3, and provide serial communication via RS 485 Modbus RTU and FC protocols. A detachable Local Control Panel (LCP) with or without a potentiometer, an LCP copy function, as well as a panel-front mounting kit for the LCP, all facilitate ease of use. In addition to the new frame size, VLT Micro Drives are also available in single-phase 200 – 240 VAC, 0.25 – 2 HP; three-phase 200 – 240 VAC, â – 2 HP; and three-phase 380 – 480 VAC, 0.5 – 3 HP power range configurations.
