Voltage Drives

Our offered Product range includes Elevator Drives and Medium Voltage Drive.

Elevator Drives

Elevators are necessary for transporting passengers and goods within buildings. Besides providing lift, the primary functions for an elevator are safety and a comfortable ride. Delta's elevator drives are equipped with a 32-bit high speed CPU providing fast response, large output torque, precise positioning control and many excellent features to ensure the elevator levels perfectly with each floor every time the door is opened. In addition, it features fast response to calculate the required starting torque when different weights enter the elevator to provide a smooth lift, and can precisely determine the car load to prevent null-speed slipping of the elevator. For additional energy-savings, Delta provides a power regeneration device, the Active Front End Unit AFE2000 Series. The AFE2000 is capable of improving system power quality and collecting the regenerative energy of the elevator to convert into reusable electricity for other facilities to use. For different industrial needs, Delta has also introduced the Integrated Elevator Drive IED Series which combines a host controller and drive function into one drive unit which simplifies the procurement and maintenance process and also provides reliable and safe rides. An elevator solution using the AFE2000 Series with Delta's elevator drive and permanent magnet motor provides energy saving results of more than 40%.

Medium Voltage Drive

Drives are used for controlling speed torque or power on motor shaft by converting fixed voltage and frequency of the supplied input . Around 65% of the world's Industrial electricity is consumed by electric motors and industry account for one-third of the worlds electricity consumption, therefore the energy saved by using ac drives would be substantial. Delta medium voltage drive is a high-efficiency, compact, high reliable and energy-saving solution. According to demand of different motors and loads, Delta provides general type and vector control type MVDs, which have a broad range of applications in segments such as power generation, oil & gas, mining, metals, cement, and public facilities. MVD is used to drive medium voltage motors loaded for instance by fans, pumps, compressors, mills, crushers, mixers, and extruders. MVD provides process control, so it can increase production efficiency, reduce energy loss, improve equipment protection, and reduce maintenance cost. Delta provides customers complete solutions with easily operated variable frequency drives.
