Q1. Why is a 480V to 380V isolation transformer commonly needed?
The 480V-to-380V configuration is one of the most frequently requested in international industrial settings. North American facilities and equipment manufactured for the US/Canadian market typically operate on 480V three-phase power. This 6 kVA isolation transformer bridges that gap directly, allowing imported CNC machine tools, precision machinery, and electronic equipment to be powered safely without rewiring or replacing motors.
Q2. Is this transformer suitable for CNC and precision machine tool applications?
Yes — this is one of its primary design targets. CNC machine tools and precision equipment are especially sensitive to voltage fluctuations and electrical noise on the supply line. The isolation transformer's galvanic separation between primary and secondary windings, combined with its ≥ 50 MΩ insulation resistance and 3000V AC dielectric strength, ensures that control circuits receive clean, stable power isolated from the industrial grid. This reduces the risk of nuisance faults, PLC errors, and servo drive trips that are commonly caused by poor power quality in workshop environments.
Q3. What voltage options are available, and how do I specify them?
Both the primary (input) and secondary (output) voltages can be independently selected from 10 standard AC values: 120V, 190V, 208V, 220V, 230V, 240V, 380V, 400V, 415V, and 480V. This covers virtually all major grid standards used globally. You can specify your required voltage pair, winding material (aluminium or copper), enclosure type (open or IP 24 protected), and whether movable wheels are needed, all at the time of order. Custom configurations beyond the standard range are also available on request.
