220V to 380V AC Voltage Converter - High-Quality Solutions from China Factory Suppliers
Reduce Initial Investment and Operating Costs
Replacing traditional dedicated transformer solutions saves over 60% in initial investment. For example, a 5kW converter driving a three-phase motor significantly lowers costs compared to applying for dedicated power lines. During long-term operation, stable voltage reduces equipment failure rates, extends the lifespan of critical components like motors and controllers, and lowers maintenance and replacement costs.
Cross-Border Equipment Adaptation and Market Expansion
Resolves compatibility issues for 60Hz equipment (e.g., imported machine tools from Thailand or Japan) operating on 50Hz grids. A case study of a multinational corporation's imported equipment adaptation demonstrates that the converter enabled seamless operation without frequency-related failures, supporting the company's international market expansion.

Frequently Asked Questions
Q
What is the BZT-40KW AC-DC-AC power converter used for?
The BZT-40KW is designed to convert single-phase 220V AC input into three-phase 380V AC output, enabling 50Hz/60Hz equipment to operate seamlessly on different grid frequencies. It is widely used for driving three-phase motors, industrial machinery, and imported equipment that requires frequency or voltage adaptation.
Q
How much can the BZT-40KW converter save compared to traditional transformer solutions?
Replacing traditional dedicated transformer solutions with the BZT-40KW can save over 60% in initial investment. It also reduces long-term operating costs by minimizing equipment failures and extending the lifespan of critical components such as motors and controllers.
Q
Can the BZT-40KW converter support equipment imported from countries with different grid frequencies?
Yes. The BZT-40KW supports both 50Hz and 60Hz output (±0.05Hz), making it ideal for adapting imported equipment — such as machine tools from Japan or Thailand — to local 50Hz grids, or vice versa, without frequency-related operational failures.
Q
What input voltage options are available for the BZT-40KW?
The BZT-40KW supports a wide range of input voltages including 110V, 120V, 220V, 230V, 240V, 380V, 415V, 440V, and 480Vac, all available as optional configurations to meet various global power supply standards.
Q
What protection features does the BZT-40KW converter include?
The BZT-40KW is equipped with comprehensive protection functions including input under-voltage, over-voltage, output over-current, short circuit, and overheating protection. Note that short-circuit protection does not support automatic recovery — the machine must be manually restarted after a short-circuit event.
Q
Can the BZT-40KW be customized to meet specific application requirements?
Yes. The BZT-40KW parameters listed are for reference only. Custom configurations are available to match user-specific voltage, frequency, power, and dimensional requirements. Please contact the manufacturer directly to discuss your project specifications.
