Based on “precise wave modification technology”, by means of real time monitoring AC power wave and modifying any distortion from aberrancy from decent sine wave at high speed, Dussun X500/X800/X1200 Pure AC Power achieved to reduce AC power wave distortion, eliminate interference and stabilize voltage in order for a highly pure AC power supply. 

   Mainly consisting of low inner resistance high speed amplifier, digital low distortion basic wave producer and high energy reservation power supply, the “precise wave modification system” modified the AC power wave at real time, continuously and precisely at a response speed several thousand times faster than wall AC power supply frequency, in order to ensure X500/X800/X1200 to output the perfect sine wave with ultra low wave distortion, ultra high voltage stabilization. 

   Adopting low distortion pure sine wave as reference, X500/X800/ X1200 not only modified the distorted input AC power wave, but also removed the DC component of the wall AC power supply in the mean time, in order to make the positive half sine wave and negative half sine wave are equivalent precisely. This process reduced the transformer hum noise of high-end large power amplifier caused by DC component from wall AC power supply down to below the threshold of human aural sensitivity. 

   X500/X800/X1200 isolated input circuit from output circuit by high performance high quality transformer. The isolated power supply system reduced largely or eliminated ground creepage interference took place broadly in audio/visual equipment or precise measure instrument, ensured the purest audio/visual quality or precise and authentic measure result.

X500/X800/X1200 output Apparent Power was related with power load with maximum continuous output power of 500VA/800VA/1200VA on the condition of good ventilation, as well peak output power as high as double of maximum continuous output power. With ultra low inner resistance, X500/X800/X1200 output voltage varied little within their specified output power range, which eliminated the voltage fluctuation due to power supply circuit inner resistance while power load changed. Their ultra strong transient power supply capacity and stable output voltage provided the most accurate dynamic response. Their agile response speed surpassed overwhelmingly that of all traditional AC power, eliminated prevalent “dynamic compression” which complained widely from normal AC power. Their electric efficiency exceeded 80% within rated power output range, much higher than that of linear reproduce type (AC-DC-AC) AC power supply. With lower heat produced, X500/X800/X1200 delivered higher power output than the former did with same size (or weight). 

   Operation as total linear model, X500/X800/X1200 reduced distortion from original AC power wave largely. Based on the inborn advantage of total linear model, the output power voltage of X500 /X800/X1200 did not contain any high frequency noise and EMI (electro magnetic interference) radiation normally produced by PWM (pulse width modulation), which was inevitable if by switch type power supply. 

   X500/X800/X1200 adopted Dussun patented “synchronized wave process” technology, which maintained frequency and phase of output power voltage and input power voltage are consistent precisely. Applied for audio/visual system, it will eliminate video rolling bar or speaker cone zero position swing. Applied for measure system, it will eliminate differential beat interference upon measure result display stably from power supply frequency difference.

   X500/X800/X1200 working model from “precise wave modification technology” possessed very strong noise suppression capacity. Equipped with built in input dual module input filters and output differential module filters, the performance they reduced circuit interference came true immediately. Helped by visual precise measure instrument (like Dussun CT-1 AC power quality meter), the big change of AC power quality between the highly contaminated AC power supply before X500/X800/X1200 processed and after processed, usually drove the observer to review AC power supply seriously. 

   X500/X800/X1200 were equipped with built in high stable digital indication meter, which could display “input AC power voltage”, “Output AC power voltage” and “Output AC power current” at real time. “Input AC power voltage” indication was not only for observing input AC power voltage, but also for observing the circuit voltage fluctuation when large power supplying. “Output AC power current” indication helped you observe the power consumption of your equipment indirectly. All of operations are very convenient. 

   Equipped with huge Aluminium/Magnesium Alloy heat sink, X500/X800/X1200 released heat produced proportionable to output power  when operation by means of silence totally. If the ventilation condition was not good and the temperature of heat sink exceeded the alarming level, the unit will power off automatically. Comparing with industrial AC power processor with fan, X500/X800/X1200 possessed higher reliability and stabilization. Under the requirement for strict noise control environment, X500/X800/X1200 pure AC power is the best choice to replace fan-type power processor.  

   X800/X1200 provided 2 groups of AC power output sockets after independent filters (4 sockets per group), in order to reduce the interference to the minimum level among these equipment connected to the 2 groups of sockets. Usually we suggested to connect analogue equipment and digital equipment to different groups of sockets respectively, or connect low power consumption equipment and large power consumption equipment to different groups of sockets respectively, in order for the lowest interference. X500 provided 4 AC power output sockets.  

   X500/X800/X1200 design met safety regulation at all. Built in high power voltage surge suppression system could suppress high voltage surge and voltage peak (eg. thunder surge) impact effectively. Their Aluminium/Magnesium Alloy case connecting to safety grounding, ensured safety protection at any time. When output power reached or exceeded the designed limit, the beeper will be alarming. If overload extremely, they will cut off power supply in order for no harm took place. Then it needed manual re-power on for power supply resume, in order to attract user’s attention.

   X500/X800/X1200 are suitable to application for high quality AC power supply and no noise interference, like high-end audio/visual audition/appreciation room, precise laboratory, etc.. For precise measure requirement, X500/X800/X1200 could be used as standard AC power supply to provide pure AC power. X500/X800/X1200 could be used as solo, or used as mutli to form a larger AC power system. Usually, one of X500/X800/X1200 could provide pure AC power for a full set of audio system or home theater system.
