Hi-Fi
ultra-low-noise DC power supply processor PS1 |
|
Power supply is the
mother of sound while sound is generated from power supply
“Playing Hi-Fi is playing power supply”
We think most of the sound problems can be solved on the
basis of power supply |
|
 |
|
What
is PS1? |
* PS1 is
a ultra-low-noise DC power processor,
* PS1 is a bank-alternating, isolated and “floated”
ultra-low-noise DC power supply.
* PS1 uses 2pcs 4S 14.8V 75C RC LiPo battery alternating
output.
* PS1 is a bank-switching, microprocessor-controller, RC
Lipo battery-based, ultra-low-noise external DC power
supply.

What
is important in power supply design?
|
* We
use 4S 75C 1800mAh RC battery in PS1, the battery
maximum output current can exceed 100A, We do not
consider the need of 100A high current. Instead, what we
think over is that the higher current is available, the
lower ESR will be obtained while the lower ESR can bring
about faster transient response. Very low ESR
(equivalent series resistance) much lower than other
type batteries, and also more lower than multiple
ultracapacitors in series，and they can discharge very
fast, thus delivering a lot of energy quickly. These are
important attributes for an audio component power
supply.
*
Speed and ultra-low output impedance over a broad
bandwidth: The power circuit with low ESR, equipped with
the Audio Note electrolytic capacitor and the V-cap CuTF
(Copper Foil Fluoropolymer Film) series Film Audio
Capacitors, compensates the high and low frequency band
to ensure that full frequency band of audio has
consistent and low enough ESR. This brings about the
obvious improvement of full-frequency sound quality as
well as excellent two-end extension.
*
As the power supply has low full-frequency ESR,
real-time transient response can be achieved for the
power requirements of full-frequency loads, and lower
noise is also easier to be realized. With parallel 6 pcs
LT3045 low-noise regulated chips, the output noise is
lower than 1uV.
*
100% galvanic isolation from the AC mains at all times.
While one bank of battery is supplying output, the
another bank is charging. The output is never connected
to the bank that is recharging, and the sophisticated
design ensures silent and smooth transitioning from one
bank to the other.
*
DC output cable is also very important, We uses ATLAS
Hyper Silver plated OFC 75 Ohm digital cable and The
Oyaide DC 2.1G highest quality DC plugs make the DC
output cable, Because we've tried to compare a lot of
cables, the 75 ohm coaxial cable is cleaner. ( If we has
find a better cable in the future, we will replace it
without notice. )

 |
| Output
voltage and plugs can be customized |
* Although it only has one power output,
the output voltage of PS1 can be customized.
* Users can customize and modify output
voltage to 5V, 7V, 9V or 12V, and even any voltage which
is not higher than 12V. All the voltages can provide 2A
and even short-time 3A output current.
* Parallel output of an USB A port will
be provided on the machine where output is modified to
5V.
* Besides the customized voltage, we also
provide customization of the output plug of DC cable,
please leave a message in the order form after your
purchase: namely brand and model + voltage of the
product to be powered. For example, QLS QA100 + 9V, We
will get the output plug information according to the
name brand and model. you can also send email to us for
consult.
* By customizing voltage and plugs, PS1
can supply power for any DC input devices whose voltage
does not exceed 12V and actual use current does not
exceed 2A.

DESIGN FEATURES |
* Always be 100% isolated from electric supply
(including the isolation from global and local ground
loop), completely blocking the interference of noise of
electric supply.
* PS1 uses 2pcs 4S 14.8V 75C RC LiPo
battery (the battery maximum output current can exceed
100A) bank-alternating output.
* Use 6pcs LT3045 low-noise LDOs for parallel output,
which only has 0.33ｕV theoretical noise.
* Use the Audio Note electrolytic capacitor and the
V-cap CuTF (Copper Foil Fluoropolymer Film) series Film
Audio Capacitors to compensate low and high frequency
band in order to ensure full frequency of audio has
consistent and steady low ESR of power supply.
* Use multiple microprocessor-controller to
intelligently manage the balancing charge and
bank-switching of batteries.
* Use dozens of N-MOS or P-MOS with super low
internal resistance and high current for the switch of
battery sets and output sources.
* When a set of batteries is supplying power, only
another set of batteries which is completely isolated
will be charged.
* Precise design can provide quiet, steady and
seamless switch from one to another battery.
* Provide a switch to batteries or DC input as output
source. With the seamless switch, battery output can be
selected for music listening; when there is no need for
music listening but long time power supply, DC input can
be selected, and it is directly outputted by the input
power after being denoised by PS1 without consumption of
battery life.
* It can be connected to input AC power in daily use,
but also supports mobile use when being separated from
AC power supply, and the life time depends on the power
consumption of load, for example, the life of power
supply for QA390（about 0.5A) is from 5 to 6 hours.
* The internal batteries have 3A charge current. When
the power switch is turned on, the power supply for load
can be disconnected manually to fully charge the two
batteries in turn so as to prepare for the mobile use
when being separated from AC power supply, the total
charge time of which is around 2 hours.
* Internal batteries provide fully balanced charge
for overcharge, over-current and over-discharge
protection.
* The output voltage is steady and with over-current
protection in order to avoid back-end devices from
over-current or over-voltage damage.
