The inverter power supply adopting AC→DC→AC conversion is defined as single-phase to three-phase power supply, which is different from frequency converters specially used for motor speed regulation.
Core function: Convert civilian single-phase 220V mains electricity into standard three-phase 380V sine wave industrial power supply.
It features stable output voltage & frequency with low waveform distortion, performance close to ideal power supply.
Ideal for remote sites where three-phase industrial electricity application is unavailable. The maximum output power is limited by the input current of 220V single-phase mains.
ALD-100 series takes microprocessor as the main control core, equipped with IGBT power module, SPWM modulation, instantaneous value feedback, digital frequency division and D/A conversion technology. Built-in isolation transformer ensures stable overall operation.
Complete protection functions including short-circuit, over-current, overload and overheat protection, automatic fault trip to guarantee long-term safe operation.
1.Adopts mature AC-DC-AC circuit structure and SPWM control technology to convert household single-phase electricity into standard industrial three-phase power.
2.The converted three-phase power maintains standard 120° phase angle with total harmonic distortion less than 2%, fully compliant with national power quality standards, compatible with all kinds of loads.
3.Solve common troubles including difficult three-phase electricity application, complicated wiring renovation and power rationing issue in factories, construction sites and rural areas.
Motors, conveyors, roller shutters, machine tools, welding machines, three-phase water pumps, cutting machines, mixers, printing machines, feed machines, crushers, air compressors, textile machinery, central air conditioning.
1.The whole series supports common DC bus parallel connection scheme.
2.Parallel connection of multiple units reduces power consumption of braking resistors. Only inrush current and input grid capacity need to be calculated during installation.
