Fact Sheet: VLT® Enclosed Drives
Extended functionality and real LHD for high-performance operation
VLT® Enclosed Drives have been designed to meet the most demanding requirements for flexibility, robustness, compactness and service-friendliness, making them a smart choice for diverse applications. They are ideal for low harmonic drive (LHD) usage, with outstanding harmonic mitigation performance.
|
|
VLT® Enclosed Drives are |
|
|
|
configurable with input/output filters, |
|
|
|
control and enclosure options to meet |
|
|
|
practically all requirements of the |
|
|
|
application, eliminating the need for an |
|
|
|
extra enclosure. |
|
|
|
Selectable input/output filters ensure |
|
|
|
highest quality of the voltage on |
|
|
|
motor terminals, as well as the lowest |
|
|
|
harmonics content of mains currents – |
|
|
|
TDD <3% and it is a best choice, when |
|
|
|
harmonics frequencies above 2 kHz in |
|
|
|
the power supply network is a concern |
|
|
|
to fulfil the IEC 61000-2-4 requirements |
|
|
|
for harmonics up to 9 kHz. |
|
|
|
Back-channel cooling |
|
|
|
A unique ducted back-channel passes |
|
|
|
cooling air over heat sinks with minimal |
|
|
|
air passing through the electronics area. |
|
|
|
There is an IP54/Type 12 seal between |
|
|
|
the back-channel cooling duct and |
|
|
|
the electronics area of the VLT® drive. |
|
|
|
This allows 90% of the heat losses to |
|
|
|
be exhausted directly outside of the |
|
|
|
enclosure, improving reliability and |
|
|
|
prolonging life by dramatically reducing |
|
|
|
temperature rise and contamination |
|
|
|
of the electronic components. Input/ |
|
|
|
output filters also use the IP54/ Type 12 |
|
|
|
-rated back-channel for cooling. |

Benefit
Eliminate the need for an extra cabinet when options are required. Save cost on equipment and reduce space requirements.
Reduce the scale of air conditioning required for the room, and even reduce the room size, for savings in up-front cost and operating expenses.
Improve efficiency of the drive and reduce audible noise.
Know one drive, know them all. Save time and cost for training, service, ordering and spare parts logistics.
Ensure highest quality of the voltage on motor terminals, as well as the lowest harmonics content of the mains currents.
Safe accessibility to control terminals, also during operation of the drive.
