Features & Benefits

Product Range

1 x 200–240 V AC 0.18–2.2 kW
3 x 380–480 V AC 0.37–22.0 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.

Display options
