Accuphase PS-530 Clean Power Supply

Ooberpad announces the availability of the power-packed Accuphase PS-530 Clean Power Supply. Every audio component draws all of its energy from the power supply which in turn is connected to the AC power grid. The Clean Power Supply components from Accuphase are products that cut out noise and impurities from the AC power line through a pathbreaking new approach, resulting in a radical improvement of the sound and picture quality of connected audio and video equipment. Without depending on an oscillator, the reference waveform is created with further improved accuracy and is linked to the power section by a balanced connection to ensure incredibly low distortion in the output waveform. The PS-530 can pack punch with as much as 510 VA, covering the requirements of most standard audio components.

Key Features:

Low-distortion reference waveform generator To generate the 230 V (120 V) sine wave reference signal, the zero-cross point at the secondary winding of a measurement circuit transformer is detected by a comparator and used by the high-precision power supply to generate a square waveform. The square wave then is routed through a newly developed 50/60 Hz band pass filter and a six-stage band elimination filter (BEF). The filter frequency is switched in sync with the input frequency, for automatic 50 Hz and 60 Hz support. By routing the signal through another band pass filter, a low-distortion sine wave (reference signal) is created that is not dependent on the input voltage. Outstanding waveform compensation power The PS-530 incorporates power waveform shaping technology that uses a clean reference waveform and works in real time to provide exactly the required compensation and remove any unwanted components. Distortion is reliably eliminated and the result is a perfectly clean source of energy. Power supply waveform and clean PS-530 output waveform Almost all electrical devices used in a household convert the AC supplied by the outlet into a DC current for powering internal circuits. This task is performed by a rectifier. The rectifier load current has a pulse waveform with a large current flowing momentarily in the vicinity of the voltage peak. This causes a voltage drop, resulting in clipping of the voltage waveform. A clipped waveform with a high amount of distortion contains many unwanted frequency components, or harmonics. When entering the audio circuitry of an amplifier through the power supply, such harmonic components can interfere with the audio signal and cause intermodulation distortion which greatly affects sound quality. When passing through the PS-530, harmonics within the audible range are largely removed, and the result is a clean sine waveform. Exceptional current capability The power amplifier which performs the waveform adding/subtraction action is designed for ample waveform compensation performance and complete operation stability. The final stage employs bipolar power transistors rated for a maximum current of 15 amperes. These devices are connected in a 10-parallel complementary push-pull arrangement which boasts a rated output current of 2.22 A (4.25 A) and an instantaneous peak current (inrush current) rating of 40 A (80 A). This demonstrates the excellent current capability of the PS-530. AC voltage stabilizer based on waveform shaping technology The control circuitry of the PS-530 is performs addition/subtraction on the alternating current from the input and then passes it on. Most of the AC energy from the input is therefore carried over to the output. The introduced loss consists only of the power required for waveform compensation, resulting in much higher efficiency and lower heat generation than with conventional AC voltage stabilizers. The frequency follows the AC input, which means that no oscillator is needed as internal signal source, and therefore no high frequency noise is emitted by the unit. Strong power supply with high-efficiency toroidal transformer and large filtering capacitors The PS-530 uses a massive toroidal type power transformer with high output capability. Rectification and smoothing is performed by two large aluminum electrolytic capacitors rated for 22,000 µF and built for high sound quality applications. This provides ample leeway. Where to buy?
