1610 pure AC power supply

The fluctuation of power supply voltage is the biggest killer of the service life of electronic products, and the quality of power supply will seriously affect the real performance of advanced audio-visual equipment. Therefore, the power supply is the root of high-end audio-visual equipment.

The Desson X series pure AC power supply based on "precision waveform correction technology" reduces the distortion of the power supply waveform, eliminates interference, and stabilizes the voltage by monitoring the AC waveform in real time and correcting any deviations from the sine wave track in the waveform at a high speed. Pure AC power.

The "precision waveform correction" system with low internal resistance high-speed amplifier, digital low-distortion reference signal source and high energy storage power supply as the main components performs the power waveform correction at various points in time with a response speed thousands of times faster than the mains cycle. Real-time, continuous, and accurate waveform amplitude correction, so as to ensure that the pure AC power supply outputs a perfect sine wave with very low waveform distortion and extremely high voltage stability. Its agile response speed is unmatched by traditional AC voltage stabilizers, and there is absolutely no dynamic compression phenomenon criticized by ordinary AC voltage stabilizers. The electrical efficiency at the rated output power exceeds 80%, which is much higher than the linear (AC-DC-AC) regenerative AC power supply. Not only does it generate low heat, it can provide more powerful power output than the former under the same volume (weight). .

The X series pure AC power supply uses low-distortion pure sine wave as the reference standard. It accurately corrects the input distortion waveform while removing the DC component in the mains voltage, so that the positive and negative half-waves of the output voltage are exactly equal. The transformer noise caused by the DC component in the mains power of the high-power advanced amplifier has fallen below the hearing threshold of the human ear.

The X series pure AC power supply completely isolates the input and output circuits through high-performance and high-quality transformers. The isolated power supply can greatly reduce or overcome the ground leakage interference that is widely present in audio-visual systems or precision measurement systems to obtain pure audio-visual quality or accuracy. Measurement results.

Desson X1610 is the latest upgraded product after X1600. Compared with Desson's previous X series power supplies, the technical performance and practical performance of X1610 have been greatly improved:

◆The output power is more pure

The most important "distortion + noise" indicator for measuring the purity of power supply output voltage, X1610 has been greatly increased by 5 times from <0.5% of X1600 to <0.1%.

The "distortion + noise" index (THD+N) of AC voltage indicates the percentage of harmful power supply harmonics, clutter and noise in the power supply voltage to the total voltage. The lower the value, the purer the power supply. The THD+N index is not only used It is used to measure the quality of mains power, and it is also used to measure the power equipment's ability to purify AC power.

For AC power, it is not easy to get low (THD+N) pure power, and it is even more difficult to get high-power pure power! Compared with the power quality standard of 5% harmonic distortion of the national low-voltage power grid, the power output after X1610 processing will be more than 50 times purer than before. The newly launched X1610 has in fact ranked the commanding heights of current power purification equipment with its excellent indicators.

For the comparison of the clutter content in the voltage before and after processing, the distortion tester in the X1610 machine can give the user a clear display of the value, and there is no need to rely on empty text to guide the user when it is impossible to see it. Users believe in and accept the actual ability of X1610 to improve power quality.

◆The output voltage is more stable

The output voltage stability index of X1610 is doubled to 0.5% on the basis of 1% of X1600.

The stability of the power supply voltage is the primary guarantee for the dynamics of audio power equipment. Unless the original home power supply line has a full-time stable voltage within the range of 0.5% (220V ± 1V) under kilowatt-level loads, the addition of X1610 will always show positive effects. . No matter how much the dynamics of the user's audio equipment is compressed due to power supply, after adding X1610, any deviations and fluctuations of the original line voltage will be eliminated, and the compressed audio dynamics will be restored immediately.

Note:

The value obtained by multiplying the reading of the ammeter on the display panel and the output voltage (220V) is called "apparent power PAV" in electrical engineering;

The actual power consumption of electrical equipment is called "active power PW";

The relationship is: PW = PAV×Cosφ.

Cosφ: power factor, φ: phase difference between load current and voltage...

When the load is pure resistance, its power consumption (active power) is the same as the "apparent power", when the load is not pure resistance, the actual power consumption is less than the "apparent power", and the difference depends on the power of the electrical equipment Factor.
