The UP28V is a special power supply, which is used to power preamplifiers BOTEG 20 db and 40 db from a computer's USB port. Electronics can increase the voltage to the required 28 V with a very stable course (without interference). The input voltage to this source may be in the range 3-20 V. The output current is dependent on the capabilities of the input power source, which may be a computer or other source of electric voltage. The status LED indicates the presence of an output voltage of 28 V.

The source on the input side has a standard USB-B (due to the higher mechanical resistance) and on the output side pair of Jacks 5 mm x 2,1 mm.
