Details:

The circuit is based on the Swiss STUDER power circuit

Ultra-low noise hifi linear power supply

Very high output accuracy, ultra-low ripple

Circuit maximum current 1.5A

The output voltage can be selected between 5V-24V.

It can provide high-precision, low-noise constant power supply for turntables, precision instruments, decoding DAC, preamplifier, etc., with short-circuit overload protection.

The output is the ON transistor15030

Adjustable resistor for US BI

The board reference voltage regulator uses a dual op amp TL072

PCB size: 94X72MM

RB:
if need DC5V output,pls use AC9V input,RB install 1K
if need DC9V output,pls use AC12V input,RB install 4.7K
if need DC12V output,pls use AC15V input,RB install 10K
if need DC15V output,pls use AC18V input,RB install 15K
if need DC18V output,pls use AC21V input,RB install 18K
if need DC24V output,pls use AC24V input,RB install 22K
