Danfoss VLT AHF 005 Design Guide

4 Product Overview
4.1 VLT® High-power Drives
The Danfoss VLT
®
drives described in this manual are available as free-standing, wall-mounted, or cabinet-mounted units.
Each VLT
®
drive is congurable, compatible, and eciency-optimized for all standard motor types, which avoids the
restrictions of motor-drive package deals. These drives come in 2 front-end congurations: 6-pulse and 12-pulse.
Benets of VLT
®
6-pulse drives
•
Available in various enclosure sizes and protection ratings.
•
98% eciency reduces operating costs.
•
Unique back-channel cooling design reduces the need for more cooling equipment, resulting in lower installation
and recurring costs.
•
Lower power consumption for control room cooling equipment.
•
Reduced ownership costs.
•
Consistent user interface across the entire range of Danfoss drives.
•
Application-oriented start-up wizards.
•
Multi-language user interface.
Benets of VLT
®
12-pulse drives
The VLT
®
12-pulse is a high
eciency AC drive that provides harmonic reduction without adding capacitive or inductive
components, which often require network analysis to avoid potential system resonance problems. The 12-pulse is built with
the same modular design as the popular 6-pulse VLT
®
drive. For more harmonic reduction methods, see the VLT
®
Advanced
Harmonic Filter AHF 005/AHF 010 Design Guide.
The 12-pulse drives provide the same benets as the 6-pulse drives in addition to being:
•
Robust and highly stable in all network and operating conditions.
•
Ideal for applications where stepping down from medium voltage is required or where isolation from the grid is
needed.
•
Excellent input transient immunity.
