VLT drive replaces expensive high voltage drive

VLT low voltage drive replaces expensive high voltage drive

19 August 2009
A standard low voltage VLT drive has successfully replaced an expensive medium voltage drive in an Indonesian crude oil deep well pump application.
The VLT drive delivers great performance with respect to the required throughput and pump protection. By adjusting the pump speed, it is now possible to extract crude from the well without rapid depletion, thereby optimizing the production and prolonging the application life time.
VLT Soft Starter MCD 500

The new intelligent VLT® Soft Starter MCD 500

The Danfoss VLT Soft Starter MCD 500 is a new soft starter in the power range from 7.5 to 800 kW (21 - 1600 A) with sofisticated start- and stopfunctions. 

New in the MCD 500 is the Adaptive Acceleration Control (AAC) function. This function developed by Danfoss adds intelligence to the soft starter. By continuously measuring the motor current and calculating the actual load, the MCD 500 fully automatically adjusts the start and stop profiles to obtain the best possible acceleration and decelaration for your application.
