In today's era of rapid industrial automation, drives serve as critical components ensuring the stable operation of numerous mechanical systems. Their performance directly impacts the efficiency and quality of production processes. Leveraging deep technical expertise and continuous innovation, V&T has meticulously developed the DTS800 series of multi-drive inverters. With distinctive technological advantages, a comprehensive product portfolio, and broad applicability, the DTS800 series delivers reliable and high-performance power solutions across a wide range of industrial sectors, significantly contributing to industry advancement.

The DTS800 series is V&T’s self-developed multi-drive inverter platform, featuring proprietary Direct Torque Control (DTC) technology. It offers fast torque response and superior speed regulation accuracy, supporting both encoder-based and encoderless DTC operation. Thanks to its unique DTC algorithm, the drive maintains high low-frequency torque and rapid torque response even without an encoder, satisfying the requirements of most industrial applications.

The V&T DTS800 drive family includes:

• DTS800-H series: Single/multi-drive inverter units
• DTS800-D series: Basic rectifier units
• DTS800-S series: Parallel slave inverter units
• DTS800-R series: IGBT rectifier/regenerative units
• DTS800-MCB: Parallel master control unit

The DTS800 series supports both single-drive and multi-drive configurations. It also enables multiple inverter units to operate in parallel to drive a single motor, facilitating scalable power capacity through parallel operation. Available in two voltage classes—three-phase AC 380V and AC 690V—the series covers a wide power range from 75 kW to 2,240 kW.
