Does the 'step-down' function work with fluctuating 460V input?

Most models have basic voltage regulation to handle minor 460V input fluctuations, ensuring stable 380V output.

What installation conditions does this transformer require?

It usually needs a dry, well-ventilated area (avoid moisture/dust) and compliance with local electrical codes for wiring.

Does the product come with a warranty, despite its good price?

Most suppliers offer a standard 12-24 month warranty, covering defects in materials or workmanship (check with the seller for details).

AI-Powered supplier vetting

SummaryThe supplier is a limited company with five employees and a valid import/export license. It reports an annual production capacity of 60,000 tons and cooperation with Chinese national and local power grids, but the provided information does not independently verify these claims. The supplier offers sample, design, full, and minor customization, provides ODM services, and reports new product activity during the past year, with one R&D engineer identified. Service limitations include no overseas agents or branches, overseas warehouses, overseas showroom, inventory capability, or offline trade-show participation. Financial records are indicated for 2021–2023, but no financial figures or assessment results are provided. No formal certification, after-sales capability, or specific customer cases are documented.

Supplier typeThe supplier is legally identified as a limited company, not part of a larger company group, with five employees and a valid import/export license. Its stated business scopes cover mechanical equipment, wind turbines and components, rail-transit systems, environmental equipment, underwater systems, hardware, and other products, indicating a diversified trading and industrial-equipment profile.

R&D capabilityThe supplier reports new products during the past year, identifies one R&D engineer, and provides ODM services. However, it has no available SDK, and no R&D spending, patents, laboratory resources, or documented innovation results are supplied; the evidence supports some innovation activity but not a broad or strongly validated capability.

Production capacityThe supplier states annual production capacity of 60,000 tons and the ability to produce multiple product lines simultaneously while shortening production cycles. It reports one-month average lead times in both peak and off-season, but no inventory capability, no confirmed manufacturing-capacity contract, and no detailed product-specific tonnage are provided.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, and minor customization. It also reports ODM service availability, providing direct evidence of broad product-design and customization support.

Client casesThe supplier states that it is one of the cooperating manufacturers for the Chinese National Power Grid and local power grids. This is a stated customer-related reference, but no customer names, contracts, project details, order scope, or independent verification are provided; no other specific customer cases are documented.

Product Q&A

Q:What voltage conversion does this transformer support?

It steps down voltage from 460V (primary) to 380V (secondary).

Q:Is this transformer CE approved? What does that mean?

Yes, it is CE approved. This ensures it meets EU safety, health, and environmental protection standards (e.g., IEC 61558).

Q:Can this transformer be used for three-phase electrical systems?

Typically yes-most 460V-380V step-down transformers in this category are designed for three-phase applications (common for industrial use).

Q:What's the main advantage of its 'good price' positioning?

The 'good price' balances cost-effectiveness with core reliability (CE compliance, stable voltage conversion) without compromising essential performance.

Q:Is this transformer suitable for industrial equipment (e.g., motors, pumps)?

Yes, it's ideal for powering 380V industrial gear that requires stepping down from a 460V supply.
