The World Pro Audio Single Power Supply pcb allows for quick and slick build of linear power supplies requiring 1 output voltages, such as with Pro Audio, Hi-Fi or instrumentation equipment. Good for tube filament supplies, bias supplies or microphone phantom power.
Dimensions: 4.32 x 2.34 inches, 0.86 oz FR4 0.059 in / 109.6 x 26.77 mm, 24.37 gm / FR4 1.5mm
Power Supply and Voltage Regulator pcb for 1 output voltage
Voltage Regulation up to 52 volts (depending on type of regulator) and current supply up to 1.5 Adc.
Output voltage is floating so it can be used for positive or negative voltage
Smart design, fast and easy component assembly - DIYers dream come true
Features large pcb traces for good current handling and to minimize rectifier noise in ground.
