Using the UltraCap™ LPS-1.2 in a quality music reproduction system will yield surprisingly audible improvements.
The LPS-1.2 is a single output, 1.1-amp linear power supply intended for powering a wide range of audio and computer devices. Examples include: UpTone's own ISO REGEN, the Sonore microRendu and ultraRendu, SOtM streamers, small DACs and headphone amps, USB>S/PDIF converters, specialty computer USB cards, SSDs, fibre media converters, PS Audio LANRover, SqueezeBox Touch, etc.
A switch on the back of the LPS-1.2 allows for setting of the output voltage to 5V, 7V, 9V, or 12 volts. This broadens the range of devices that can be powered. Maximum guaranteed output current at all voltages s still 1.1A
The output voltage regulators have been changed to the truly extraordinary (0.8µV/RMS!) Linear Technology LT3045 a pair of them paralleled in a configuration that further lowers output impedance. We are down into the 3mOhm (10Hz-100KHz) range now!
The input and output jacks of the are standard 5.5mm x 2.1mm size DC barrel connectors.
A power on/off switch has been added. Some people prefer to turn off the supply at times. Now you can do so without having to unplug any cables
The LPS-1.2 can run off chargers from 7-24V. The new 9-volt and 12-volt output settings on the LPS-1.2 necessitates the use of a higher wattage AC>DC power supply to “energize”/charge the unit. The strict requirement for the charger is now 36 watts but flexible with regards to the voltage of the charger but the charger voltage times its current capability MUST equal 36W or greater. (So 7.5V/4.8A, 9V/4A, 12V/3A, 18V/2A, 24V/1.5A are all acceptable charger ratings.)The UltraCap LPS-1.2 has a small, 3-pin (standard 0.1” header pin spacing) port for measuring output voltage and device current draw. Typically measuring the current draw of a device requires putting an ammeter in series with the power cable (DC or AC) feeding it. But this clever port provides a measurement of current with a voltage: 1 Volt equals 1 Amp. So if you measure 0.2V (across the pins labeled G—for ground—and I—for current), that means the device you have attached to the output is drawing 0.2A or 200mA. The pin labeled V always outputs the voltage that the LPS-1.2 is set to. Included
Customer comments:''Hooking up the LPS-1.2 power supply to our USB Regen resulted in a MAJOR AUDITORY BREAKTHROUGH. Also our Mac mini sounds significantly better when powering the USB Regen from the LPS-1.2!''''Regarding the LPS-1.2 I can only say that it has lifted my entire setup to a new level. I now have a much better instrument and voice separation, blacker background, and a wider & deeper soundstage. It has worked wonders with my SoTM SMS-200''
- One 70cm, DC cable with 5.5mm x 2.1mm plugs at both ends (correct for REGENs, the Sonore Rendu and many other popular devices which use that size)
- A 7.5V/4.8A/36W world-voltage-compatible tabletop SMPS for "energising" the UltraCap™ LPS-1.2. Optional local AC power cable (IEC 'kettle' connector)
