Import Dc Drive Stack Controller — Buy in Bulk from Supplier in India

This is a compact digital controller designed for retrofitting analog-controlled DC drives, manufactured by Sprint Electric UK and distributed by Vaishnavi Electronics. The unit supports both 2-quadrant and 4-quadrant DC drives with a power range from 100 kW to 1000 kW, featuring an integrated field controller rated up to 32 A. Physically, it weighs 8 kg and measures 300 mm x 200 mm x 175 mm, making it suitable for industrial panels with limited space.

Constructed for industrial environments, the controller interfaces with existing DC drive systems to modernize control schemes without full replacement. Typical applications include material handling, textile machinery, and metal processing where precise speed and torque control are required. The digital architecture allows for programmable acceleration, deceleration, and current limits, which are standard features in contemporary DC drive retrofits.

Primary buyers include OEMs upgrading legacy equipment, system integrators, and maintenance teams in factories running older DC motor installations. The unit is particularly valued for its ability to extend the lifespan of existing machinery while improving energy efficiency. For bulk orders, buyers should confirm compatibility with their specific drive models, as the controller is designed to match Sprint Electric’s reference architectures.

Vaishnavi Electronics operates from Bangalore, Karnataka, with a registered address at 271 1st A Cross, 2nd Phase, 6th Block, BSK 3rd Stage. The company specializes in industrial automation components, including drive controllers and retrofitting solutions for legacy systems. Its focus is on providing technical products that bridge gaps between older machinery and modern control requirements.

The supplier’s profile does not list active trust signals such as response rates or verification badges, which indicates a passive presence in digital channels. Buyers are advised to contact Vaishnavi Electronics directly to assess technical support capabilities, lead times, and after-sales service. The company’s product offerings cater primarily to Indian industrial markets, with potential for export to regions requiring Sprint Electric-compatible hardware.
