Enclosed IP21 or IP54 drives
14 June 2016
The VACON 100 range of AC variable speed drives from Danfoss Drives, has been extended to include standard enclosed drives supplied ready for immediate installation and commissioning.
With a choice of IP21 or IP54 ingress protection ratings, the new drives include an auxiliary front door to provide safe access to control circuits.
Access to the control section of the drive can be reached through a small auxiliary door in the front of the enclosure, without the need to open the full-height main door. In this way, the low voltage area can be reached without the safety risks associated with exposing the high voltage sections of the drive.
The new drives also incorporate an interesting cooling channel design. Integrated du/dt filters and common mode output filters enable efficient back channel cooling to be used and, in the IP54 versions, no additional air filters are needed in the main cooling airflow.
The IP21 versions of the drives, which are intended for installation in control rooms and similar environments, and the IP54 versions, which can be used in demanding environments without further protection, are both available with power ratings up to 630 kW on 400 V supplies and 800 kW on 690 V supplies.
VACON 100 drives also feature, as standard, integrated support for ModBus TCP and Profinet I/O connectivity. Plug-in option cards are available to provide support for other popular communication and fieldbus standards.
