Q1: What is the difference between a 3-phase autotransformer and an isolation transformer?
A 3-phase autotransformer uses a single continuous winding for both input and output voltage transformation, making it more compact and cost-effective. An isolation transformer has separate primary and secondary windings and provides electrical isolation. For voltage conversion applications like 380V to 220V step-down, an autotransformer is typically more economical and efficient.
Q2: Can this 1 kVA autotransformer support other voltage combinations?
Yes. Besides the standard 380V to 220V/200V, other voltages such as 120V, 230V, 240V, 400V, 415V, or 480V can be customized. Please confirm your input/output voltage and frequency requirements before ordering.
Q3: Is this dry-type autotransformer suitable for continuous industrial operation?
Yes. With H-class insulated copper windings, silicon steel core, and reinforced terminals, this 3-phase autotransformer is designed for stable long-term operation in CNC machines, automation systems, and laboratory equipment.
