Однофазный преобразователь 220 В в трехфазный 380 В

Where It’s Used

• Workshops, home factories and commercial premises lacking three-phase service
• Rural, remote or temporary sites (farms, field operations)
• On-site renewables: convert PV or small wind output to three-phase for local loads
• Retrofit projects where applying for three-phase supply is impractical or costly

Key Benefits & Features

• True sine-wave three-phase output — THD < 2% for smooth motor and sensitive equipment operation.
• High conversion efficiency — SVPWM control and premium IPM deliver efficiencies > 93% and low no-load losses.
• Fast transient response — output stabilizes within 50 ms to handle load changes.
• Robust protection — built-in short-circuit, overload and over-temperature protection for safe continuous operation.
• Power frequency isolation transformer — isolates AC and DC buses to eliminate interference and improve safety.
• User display & diagnostics — LCD reports input DC voltage, output frequency/voltage, power (kWh), runtime and fault codes.
• Cost-effective — uses standard single-phase billing while supplying industrial three-phase loads — avoids three-phase application hassles and fees.
• Cleaner mains — filters out disturbances and provides cleaner power for downstream equipment.
• Long service life — industrial components and cooling design for extended reliability (design life > 15 years under normal conditions).

TECHNICAL PARAMETERS

How to Choose the Right Model

• Match continuous motor load (kW/kVA): pick a converter with continuous output ≥ the motor’s rated kW plus startup surge margin (motors often need 2–3× starting current).
• Consider duty cycle: frequent starts/stops or long heavy loads may require a larger unit or enhanced cooling.
• Check environment: outdoor or dusty sites require higher IP rating and filtered air intake.
• Verify supply capacity: the converter’s output is limited by available 220V input current — ensure mains can supply the required input amps.
• Installation & grounding: follow local electrical code; recommend a qualified electrician for wiring and earthing.

ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ

Q: Can this run induction motors and compressors?
A: Yes — the DZW is optimized for motor loads. Because it produces a low-distortion sine wave, motors start and run smoothly. For large motor starts, size the converter to allow starting surge (consult the technical sheet).

Q: How is this different from a rotary phase converter?
A: Unlike rotary converters, the DZW uses solid-state conversion (SVPWM inverter) to produce a stable, low-distortion three-phase sine output close to utility quality — better for sensitive electronics and variable-speed drives.

Q: Will it save me money?
A: It can be more economical than applying for three-phase service (installation fees, upgraded wiring). However, energy consumption depends on loads — the unit converts what you draw from single-phase mains, so size and usage determine cost.
