FAQ
Frequently Asked Questions
Quick answers before you submit transformer selection parameters.
Voltage conversion means changing one voltage level to another so that the power supply matches the required operating voltage of the equipment. In industrial applications, this is usually done with a step-up, step-down or isolation transformer.
Transformer capacity is usually selected according to the total load power, equipment starting current, operating conditions and safety margin. Please provide the load capacity in kVA or kW, equipment type and working duty so Winzele engineers can recommend a suitable transformer.
Yes. A properly designed step-down transformer can convert 480V to 380V or 400V for imported industrial machines and factory equipment. The final design should also confirm phase, frequency, load capacity, installation environment and protection requirements.
An isolation transformer provides electrical separation between input and output circuits, which can improve safety and reduce the transfer of electrical disturbances. An auto transformer is usually more compact and cost-effective, but it does not provide full electrical isolation. The right choice depends on your safety requirements, equipment type and application conditions.
Please provide input voltage, required output voltage, single-phase or three-phase, frequency, load capacity, equipment type, installation location, isolation requirement, cooling method and working environment. These details help us recommend the correct transformer specification and quotation.
