------ Special high-precision frequency power can be customized

[Applications] mainly for the manufacture or export trader of electricity export to detect electrical products, debugging and precision instruments for power supply. Widely used in home appliances manufacturing, electrical, electronics manufacturing, IT industry, computer equipment, laboratories and the like; electrical, electronics manufacturers such as: switching power supplies, transformers, electronic ballast, AC fan, uninterruptible power systems, chargers, relays, compressors, motors, passive components and other products of the test power; aviation / institutions such as: airport ground facilities, shipbuilding, aerospace, Institute of test power. [Features] variable frequency power supply using sinusoidal pulse width modulation SPWM design, with imported Japanese Mitsubishi, Siemens or Infineon 1GBT, drive circuit promote independent self-developed, stable and reliable, long life; with the flow, short circuit , overvoltage, undervoltage, overload protection and alarm fault display function, to ensure the safety of electrical equipment and power inverter products; three-phase power can be adapted to any unbalanced load: main circuit and control circuit according to three independent single-phase power supply design, LCI structure, three single-phase inverter circuit output difference between each 120 °, three-phase unbalanced voltage not exceeding 1V, independent of each other in the transformer primary electrical output connected into a star, any phase can be As a stand-alone single-phase power, and can adapt to any unbalanced load; high stability, due to the structure of the double-loop feedback circuit transfer aviation power products development, inner current guarantee linear load waveform distortion. ★ rated power: 3 --- 6400KW output single-phase voltage: 0 --- 300V, three-phase: 0 ☆ --- 520V continuously adjustable output frequency: 50/60/100/200 / 40--70HZ frequency stability : fixed-frequency ± 0.01%, ± 0.1% FM
