The World Pro Audio Single Voltage Regulator pcb allows for quick and slick build of linear power supplies requiriing 1 output voltage, and can be used in conjunction with WPA Power Supply pcbs to obtain additional needed filtered/regulated voltages. Can be used without rectifier and filter cap if fed from regulated dc supply.
Dimensions: 1.34 x 1.92 inch, 0.23 oz / 34.04 x 48.64 mm, 6.49 gm
Accomodates Rectifer, Filter and Voltage Regulator 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.
Feed from transformer secondary or regulated dc supply
Pads with ample hole size are provided for connection of input voltage, or 1 of 2 circuit screw type Euro terminal can be installed.
Output voltage leads can be soldered via pads with ample hole size, or 1 of 2 circuit screw type euro terminal can be installed
The Regulator design:
Uses full wave bridge rectifer for floating output. Can be used for positive or negative voltages. Standard full wave rectification can be easily implemented.
Multiple choice of filter capacitor size:
1 snap-in filter capacitor with 0.866 inch (22 mm) diameter, and 0.4 inch lead spacing
1 radial filter capacitor with up to 0.866 inch (22 mm) diameter and 0.3 inch or 0.4 inch lead spacing
2 radial filter capacitors of up to 0.45 in diameter and 0.2 inch lead spacing
Designed for TO-220 regulator, LM317 or any with equivalent pinout, such as LD1085 and LT1085
Up to 2 output filter caps can be installed
Voltage can be set with a trimpot or a resistor and trimpot.
Provision for voltage indicating led and led current set resistor
