SFC11Series AC variable frequency power supply
Single-phase input single-phase output series
SFC series variable frequency power supply is specially designed and manufactured for 60Hz import and export equipment. It can be used as power supply for imported 60Hz electrical equipment and production lines; it can also be used as test power supply for export electrical product production lines. Its main feature is to provide pure and reliable sine wave power output with low harmonic distortion, high frequency stability and voltage regulation rate. In addition, it can also support 400Hz high frequency avionics and military equipment. SFC series variable frequency power supply can solve almost all power supply problems, such as mains high voltage, mains low voltage, instantaneous voltage drop, damping oscillation, high voltage pulse, voltage fluctuation, surge voltage, harmonic distortion, clutter interference, frequency fluctuation, etc. Power problem.
■ Multifunctional AC source test equipment - simulates different types of power sources around the world, supports 400HZ frequency of national defense military detection, avionics, navigation, communications and other equipment.
■ Produces purified AC output power - powerful direct digital synthesis (DDS) sine wave generation, pure sine wave output with low harmonic distortion.
■ Excellent stability - output load voltage regulation rate ≤±1%, output frequency ≤0.01% (its output frequency is generated by quartz oscillation, so it has a very stable and accurate frequency).
■ Fast response - for 100% loading/unloading, the output load can be stabilized within ±1% within 2ms.
■ Multiple protection functions - with over-voltage, over-current, over-temperature, IGBT drive proprietary technology, the output short-circuit guarantees the user to ensure that it will not be damaged due to short-circuit of the load.
■ Strong overload capacity - allows 100% full load long-time use, the instantaneous current can withstand 3 times the rated current, and will not cause voltage drop, all kinds of loads can be used.
■ Good man-machine interface - digital display of voltage, frequency, current, power/PF measurement, the accuracy can reach 0.5 level, the source and meter are integrated, and the operation is simple.
