User Guide
Made in U.S.A.
Thank you for purchasing an UpTone Audio UltraCap LPS-1.2.
This revolutionary and sophisticated ultra-low-noise 1.1-amp linear power supply uses
140 Farads of supercapacitors and optical isolators in a bank-switching arrangement,
controlled by software logic in an FPGA. While one bank of supercaps feeds the output
regulators, the other bank charges. At no time is the external AC>DC “energizing”
supply ever connected to the output of the LPS-1.2. 100% isolation from both AC
mains noise and, as importantly, complete blockage of detrimental leakage currents is
achieved.
In a quality music system, the UltraCap LPS-1.2 will, depending upon the components
powered, result in worthwhile sonic improvements. We suggest you prioritize using the
LPS-1.2 on devices which are directly in the analog or digital audio signal path, and/or
in locations where an isolated power supply is likely to be most effective.
The LPS-1.2 can be set by the user to output any one of four DC voltage levels: 5 volts,
7 volts, 9 volts, or 12 volts. The size of both the DC input and output barrel jacks is
5.5mm x 2.1mm, and the center pin is positive. The LPS-1.2 ships with a 70cm long,
16awg coaxial DC cable with 5.5mm x 2.1mm plugs at both ends.
During manufacturing, each unit has been carefully tested under full load to assure
reliable performance within its limits. Your LPS-1.2 is covered by a 3-year warranty.
Do contact us if you ever have difficulty or need advice or service.
Please read this entire instruction booklet to learn important information
about installation and operation of the UltraCap LPS-1.2.
Installation and use of the UltraCap LPS-1.2 is simple:
Charging Power:
The DC power input requirements of the UltraCap LPS-1.2 are not related to your in-
tended output voltage and load. The quality of the output of the “energizing” supply
does not at all affect the quality of the LPS-1’s output to your component. However,
the LPS-1.2 does require that the AC>DC supply feeding its charging circuits fall into
a specific voltage range and with enough current for the task.
All LPS-1.2 units are shipped with a fully certified, world-voltage compatible, 7.5 volt
/ 4.8 amp AC>DC adapter. This 36-watt adapter is a higher wattage model than that
supplied with either UpTone’s REGEN products or the first generation LPS-1. The
expansion of output voltage range (to include 9V and 12V) with the newer LPS-1.2
necessitates use of an “energizing”/charging supply capable of at least 36 watts.
If you choose to charge the LPS-1.2 with an AC>DC supply other than the one we
include, then it must be a regulated power unit that falls within the following output
ranges: • 7.5 volts / 4.8 amps, • 9 volts / 4.0 amps, • 12 volts / 3.0 amps, • 18
volts / 2.0 amps, or • 24 volts / 1.5 amps.
Do not attempt to charge the LPS-1.2 with a supply of less than 7.5V or more than
24V. Be certain that the AC>DC unit is capable of at least 36 watts (higher is okay).
During use, it is normal for the case of the LPS-1.2 to become very warm–perhaps
even hot–under full load. Do not worry at all. Even when hot, all parts are operating
at less than half their thermal ratings.

Startup and Operation:
It is recommended that during the first days of use you place the LPS-1.2 with its
back panel facing where you can see the POWER LED lamp. The lamp changes color
to indicate status.
1) Set the blue rotary switch to the desired output voltage using the included screwdriver.
2) Attach the supplied DC cable to the device you wish to power and then to the
“OUTPUT” jack of the LPS-1.2.
3) Plug the supplied AC>DC power adapter into the “+DC IN” jack.
4) Fully press the Power Switch button of the LPS-1.2.
4) Wait while the LPS-1.2 performs all its startup/reset calibrations; The light will be
red, then orange, and finally green. Depending upon the output voltage selected
and the prior state of charge of the unit, the red>orange>green boot time will take
between 15 seconds and 120 seconds.
Meaning of the Power LED Colors:
GREEN: • Normal operation; the LPS-1.2 is outputting the DC voltage it is set to and
the current load of your attached device is not exceeding 1.1 amps.
RED: • Flashing red (five red pulses, then a brief pulse of green) means that your
connected device is drawing more than a continuous 1.1 amps. The LPS-1.2 will shut
off its output voltage and then return to solid green once the load is reduced.
• Solid red means the LPS-1.2 is not outputting any voltage. Unplug the AC>DC sup-
ply from the input, wait until the red light goes off completely, then plug the charging
supply back in and wait through the entire red>orange>green boot cycle.
We hope the UltraCap LPS-1.2 enhances your music system.
