1. Product Overview
2. Core Competitive Features
✅ Single 220V to Balanced Three Phase 380V Conversion
Converts ordinary single-phase household/shop power into standard symmetrical three-phase 380V power, enables normal operation of three-phase motors, CNC lathes and injection molding machines without three-phase grid wiring renovation.
✅ Complete Electrical Isolation Winding Design
Independent primary and secondary isolated windings block power grid harmonic interference, suppress voltage surge spikes, effectively protect precision industrial equipment from unstable mains damage.
✅ Wide Full Power Range 1kW–100kW
Complete power specifications cover small light-load machinery to heavy industrial equipment: 1kW, 2kW, 3kW, 5kW, 10kW, 15kW, 20kW, 30kW, 50kW, 80kW, 100kW to meet all workshop load demands.
✅ Multi Digital & Analog Real-Time Monitoring Panel
Two high-definition digital screens display input voltage and output current; analog pointer meter tracks real-time three-phase output voltage for intuitive power status observation at a glance.
✅ Independent Working & Overcurrent Protection System
Green WORK running indicator lamp, red PROTECT emergency protection button, built-in overcurrent overload auto-shutdown circuit to prevent transformer burnout under abnormal heavy load.
✅ Mobile Wheeled Cabinet with Portable Handles
Four heavy-duty silent rolling casters under the cabinet plus dual top lifting handles, easy to move the transformer to different machine stations without complex disassembly.
✅ Fully Customizable Input & Output Voltage
Support custom single-phase input voltage (110V/220V) and three-phase output voltage (208V/380V/400V/440V) to adapt to global regional power grid standards.
✅ Built-In Input & Output Circuit Breakers
Independent air switch breakers on input and output terminals for safe quick power cut-off during equipment maintenance or fault troubleshooting.
✅ Factory Spot Stock & OEM Customization Support
Direct factory supply without intermediate markup, abundant ready stock for fast shipment; accept customized voltage parameters, cabinet size and private logo printing for overseas bulk export orders.
