Drives & Controls '99 - Danfoss enters low power sector with compact VLT
Here's just a foretaste of what you will able to see at this year's
Drives & Controls show, located once more at the Telford Exhibition
Centre - and rapidly outgrowing that venue, judging by the size of the
exhibitor list. The show runs from 16 to 18 March and there is much to
see. Make a date in your diaries!
The wraps come off a new low-power (0.37-7.5kW) VLT drive on Danfoss'
stand this year. The VLT 2800 is a compact, multi-purpose unit that can
be used in a variety of industrial applications, including variable
torque applications such as pumps and fans, and constant torque
applications such as conveyors and compressors. Despite its compact
dimensions, the new VLT packs a good deal of functionality. It has
built-in compliance with the 1A RFI standard and, thanks to an integral
dc link choke, it does not require any external line reactor. Advanced
features include automatic motor tuning and dc bus access, which enables
drives to share the load on multiple drive applications. A useful
feature, particularly for pump and fan applications, is an integral PID
controller. This ensures that the drive delivers full control during
closed loop operation and also saves on cabinet space. The new VLT can be
operated from a common hand held control panel, or over an RS485 serial
link.
