Compact VLT® Micro Drives

Aug. 26, 2009
Danfoss Drives has added an M5 frame size to its VLT® Micro Drive family.  The M5 frame size is 11.5 in. H x 6.5 in. W x 9.8 in. D, and covers the three-phase 380 – 480 VAC, 25 – 30 HP range.   The drive offers true side-by-side mounting without any derating due to its compact book-style design.  An Automatic Energy Optimizer function allows the drive to consume less energy while the Automatic Motor Adaptation feature leverages the motor’s full operating potential.  Users will also benefit from up to 150% more torque for up to a full minute, eliminating the need to oversize the drive.In addition to the new M5 frame size, VLT Micro Drives are also available in single-phase 200 – 240 VAC, 0.25 – 2 HP; three-phase 200 – 240 VAC;  three-phase 380 – 480 VAC, 0.5 – 3 HP; and three-phase 380 – 480 VAC, 15 – 20 HP power range configurations.   The VLT Micro Drive is a genuine VLT variable frequency drive with high reliability, user-friendliness and condensed functionality that is extremely easy to commission.  Users simply connect the motor and power cables, turn the control knob, and watch the motor speed change. 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.
