Smallest high power drive in its class

Third Quarter 2005 Electrical switching & drive systems & components

High efficiency components and innovative designs make Danfoss VLT high power drives compact as well as easy to commission and operate. These high power drives are designed for side-by-side mounting in standard Rittal cabinets. The IP00 enclosed VLT drives are robust and sufficiently protected for a host of applications.

The modular design of the largest VLT drives provided maximum flexibility to satisfy a wide range of application needs. The drive inverters use the same power components as the standalone drives, reducing the number of spare parts required. In the event a repair is necessary the modular drives are designed to allow front door access to all key components, minimising downtime.

Intelligent cooling design optimises operation. Accessories allow for easy installation of IP00 high power VLT Series units in standard Rittal TS8 enclosures. The kit is available for 1,8 and 2 m high enclosures. The minimum depth of the enclosure is 500 mm and the minimum width is 600 mm for a single frequency converter to be installed. Multiple drives can be installed side by side in larger Rittal TS8 enclosures of same height.

Standardised mounting

The options provide a mounting solution in standard Rittal TS8 enclosures where the customer can utilise the cooling attributes of the high power drives. The design provides:

* Quick and easy installation with standard options saving time and cost.

* Utilisation of the internal fan of the drive to remove the heat, avoiding cost of additional fans in the Rittal enclosure.

* Provides removal of up to 85% of the heat of the drive through the ductwork keeping internal components cooler.

* Separate cooling air for the power components keeps the interior of the drive clean of environmental contaminants.

* Protection up to IP54/NEMA12.

* Consistent style of installation if other components are installed in standard enclosures.

Dedicated filters

Dedicated filters are available to minimise potential harmonic disturbance to other sensitive equipment that is connected to the same power supply. Harmonic disturbance is an issue to be considered with high power applications. All Danfoss drives have built-in DC coils that minimise harmonic disturbance, but if additional filtering is specified Danfoss offers a full line of filter solutions.

Fieldbus and software tools

Danfoss offers numerous serial communication options and software programs to support a wide range of applications. Since all units in a VLT drive series utilise a common control principle, the fieldbus or software tool used to control one VLT drive can be used to control any VLT drive - regardless of power or size.
