Servo Drive 3000VA Single Phase Control Transformer 380V To 220V Step Down

Our 3000VA single phase control transformer is a high capacity power solution engineered to step down 380V input to a stable 220V output for servo drive systems, CNC machine tools, and industrial automation equipment operating on three phase plants with single phase control loads. This JBK series control transformer provides ample reserve capacity for servo amplifiers, spindle drives, brake rectifiers, and auxiliary equipment, preventing voltage sag during peak current demand. The high permeability silicon steel core and high purity copper windings deliver ≥90% working efficiency with low temperature rise, while the dry type air cooled enclosure ensures safe, quiet, and maintenance free operation inside electrical cabinets. With ±2% output precision and Class F insulation, this transformer guarantees stable and safe power for precision automation applications worldwide.

• High Capacity 3000VA Output: Generous power reserve supports servo drives, spindle motors, and multiple auxiliary loads simultaneously without output voltage sag or thermal overload.
• 380V to 220V Conversion: Dedicated step down configuration converts 380V plant supply into 220V single phase power for equipment designed for lower voltage markets.
• Stable Precision Power: ±2% output precision and zero additional waveform distortion protect sensitive servo amplifiers and CNC controllers from voltage irregularities.
• Superior Thermal Performance: High efficiency core and winding design keeps temperature rise below 80K and working efficiency at ≥90%, extending insulation life and reducing cabinet heat load.
• Heavy Duty Construction: Reinforced terminals, high purity copper windings, and premium silicon steel core materials are selected for continuous industrial duty and long service life.
• Versatile Customization: Input and output voltage combinations, terminal arrangements, and enclosure sizes can be customized to match specific machine tool and automation system requirements.

This 3000VA control transformer is widely deployed in CNC lathes, machining centers, servo press machines, injection molding machines, and automated production lines where 380V plants supply single phase 220V control and drive circuits. It is also used in elevator control cabinets, textile machinery, printing presses, and packaging lines that require a dedicated high capacity control power source. Custom voltage taps, center tapped secondaries, and shielded windings for electromagnetic compatibility can be added for OEM applications, and bulk orders receive priority scheduling with flexible lead times.

Units are packed in reinforced non fumigation plywood cases with internal foam protection; the reference packing size is 24X24X24CM with a gross weight of approximately 28KG. Our factory is certified to CE, ISO9001, and UL standards, and every control transformer passes full process quality inspection including raw material verification, winding resistance testing, insulation testing, and rated load temperature rise testing before shipment. We offer OEM/ODM services, a minimum order quantity of one unit, and lifetime technical support with optional on site engineering service for large projects.
