Multiuse Regulated & Unregulated Power Supply Board
This board provides both regulated and unregulated DC outputs for electronic circuits and audio applications. This is a bare PCB and supports multiple regulator configurations based on components used.
Regulated Outputs:
+5 V DC, +12 V DC, -12 V DC (using L7805, L7812, L7912)
Optional: +15 V DC, -15 V DC (using L7815, L7915)
Maximum output current: up to 1.5 A (combined, depending on regulator selection, load, and heat dissipation)
Recommended transformer: 12-0-12 VAC, 1 A to 2 A (step-down)
Unregulated Output:
Maximum DC voltage: up to 50 V DC (no-load condition)
Maximum current capacity: up to 10 A (depends on transformer rating and load)
Rectifier: GBU1010 bridge rectifier
Filter capacitors: 2200 µF or 4700 µF / 50 V × 4
Recommended transformer: up to 30-0-30 VAC (step-down)
Configuration:
Supports operation using either a single transformer or two separate transformers for regulated and unregulated sections
Output voltages depend on the regulators and components installed on the PCB
Intended Use:
Power supply for audio amplifier circuits (e.g., subwoofer and multi-channel audio systems)
Bench power supply for electronics testing and development
General-purpose DC power source for hobby and DIY electronic projects
