CNC Machine Tool 50KVA Three Phase Dry Type Voltage Transformer 380V To 220V Step Down

Our 50KVA three phase dry type voltage transformer is a precision power conversion solution designed to step down 380V input to a stable 220V output for CNC machine tools and precision manufacturing equipment. This SG series transformer combines a high permeability silicon steel core, high purity copper windings, and F class insulation to deliver clean, isolated, and tightly regulated power that keeps servo drives, spindle motors, and control systems running at peak performance. The oil free dry type design makes it safe for indoor installation next to sensitive equipment, while the compact enclosure and low noise operation allow it to be integrated directly into machining workshops without special foundation work or fire proofing. It is the trusted voltage transformer choice for machine tool builders, plant maintenance teams, and precision engineering companies worldwide.

• Precision Step Down for CNC: Converts 380V workshop power into stable 220V output specifically for CNC machining centers, automatic lathes, milling machines, EDM machines, and robotic production cells.
• Protection for Sensitive Drives: ±2% output precision and complete electrical isolation shield servo amplifiers and PLC controllers from voltage fluctuation, harmonics, and transient surges that cause positioning errors and board failures.
• Advanced Insulation System: F class insulation materials pass 3500V high voltage tests and 2500V dielectric strength testing, guaranteeing safe operation and long winding life even under continuous duty cycles.
• Real Time Digital Monitoring: Integrated digital display shows each phase voltage and current, allowing operators to verify power quality at a glance and detect abnormal conditions before they interrupt production.
• Ultra Quiet Operation: Optimized core stacking and precision winding techniques keep noise below 55dB, creating a comfortable working environment in modern machine shops.
• Oil Free and Maintenance Free: Dry type construction requires no oil changes, no leak inspections, and no special containment, cutting total ownership cost dramatically compared with oil immersed transformers.

This 50KVA voltage transformer is the ideal power companion for CNC machining centers, automatic turning lathes, vertical and horizontal milling machines, wire cut EDM equipment, laser cutting machines, industrial robots, and automated assembly lines. It is also widely used in precision instrument laboratories, medical imaging facilities, packaging machinery, and textile production lines where stable 220V power directly affects product quality and machine accuracy. Multi tap output options allow the same transformer to feed 220V, 200V, or 110V equipment from a single 380V supply, simplifying factory electrification projects and reducing the number of dedicated power sources required.

Standard export packaging uses a high strength carton for small quantities and a reinforced non fumigation plywood case for larger orders; the reference packing size is 55X48X80CM with a gross weight of approximately 150KG. All units are produced in our CE, ISO9001, and UL certified factory and pass complete performance testing, including insulation resistance, voltage ratio, no load loss, and temperature rise checks, before release. We provide OEM/ODM services, one set minimum order quantity, 3 to 7 working days delivery for standard models, and lifetime free technical guidance for installation and commissioning.
