TechnoBuzz

The sound characteristics of this power board: the background is very dark, the resolution is extremely high, the positioning is accurate, the sound field is open, the bass is deep, the strength is flexible, the treble is lingering, and the sound penetration is high.

(Declaration: The WIMA film capacitor on the board is an imported disassembly machine.)

This power supply is built with a lot of money: as shown in the figure:

The power board can be used as a front-end power supply, headphone amplifier power supply, desktop power amplifier power supply, etc.

The introduction of this power board is as follows:

1. Board size: 18CM×11CM;

2. Output current: 1A

3. Output voltage:

6 independent voltage regulators, respectively as follows:

Output voltage +V1: The default is +15V, the voltage can be adjusted, the adjustment range: +9V to +22V,

For use in amplifying circuit;

Output voltage +V2: The default is +15V, the voltage can be adjusted, the adjustment range: +9V to +22V

For use in amplifying circuit;

Output voltage +15V, this voltage is provided by Zener diode for servo circuit use;

Output voltage +V: The default is +24V, the voltage can be adjusted, the adjustment range: +20V to +45V,

For use in amplifying circuit;

Output ground: GND

Output ground: GND

Output voltage -V: The default is -24V, the voltage can be adjusted, the adjustment range: -20V to -45V,

For use in amplifying circuit;

The output voltage is -15V, this voltage is provided by the Zener diode for the use of the servo circuit;

Output voltage -V2: The default is -15V, the voltage can be adjusted, the adjustment range: -9V to -22V

For use in amplifying circuit;

Output voltage -V1: The default is -15V, the voltage can be adjusted, the adjustment range: -9V to -22V,

For use in amplifying circuit;

Note: +V1 and +V2 are in the same group, -V1 and -V2 are in the same group,
