VLT® Micro Drive
The VLT® Micro Drive is a general purpose drive that can control AC motors up to 7.5 kW. It is a small drive with maximum strength and reliability. RoHS compliant The VLT® Micro Drive is manufactured with respect for the environment, and it complies with the RoHS Directive. The perfect match for:
- Industrial appliances
- HVAC applications
Features and benefits
Product range
1 x 200–240 V AC 0.18–2.2 kW
3 x 200–240 V AC 0.25–3.7 kW
3 x 380–480 V AC 0.37–7.5 kW

VLT® Micro Drive is a genuine VLT® frequency converter with unsurpassed reliability, user-friendliness, condensed functionality, and extremely easy to commission. Terminal numbers are named in the same manner as in the rest of the VLT® family.
Despite the compact size and the easy commissioning, VLT® Micro Drive can be set up to perform perfectly even in complex application set-ups. Approximately 100 parameters can be set to optimize energy efficiency and operation.

Coated PCB standard
For harsh environments.
Real space saving side-by-side
A compact book style design allows real side by side mounting without derating.
Minimum penetration of dust
VLT® Micro Drive is designed to keep the forced ventilation away from the electronics. Printed circuit boards are well protected inside the drive.
Built-in RFI
Radio disturbance from motor cables is limited with the built-in RFI filter allowing for 15 m motor cables (screened). Meets EU norms.
Built-in brake functions
With built in DC and AC brake functions, VLT® Micro Drive can transform kinetic energy in the application into braking power to slow down the motor. A brake chopper is built-in the drives from 1.5 kW upwards.
