Description

40KuF Power Supply

Components

1. 1×680Ω resistor 1/4W.

2. 4×Diode 1N4007.

3. 3×2 pin XHB connector 2.54 mm.

4. 1×7805 +V Regulator.

5. 1×47uF capacitor 25V.

6. 1×2200uF capacitor 25V.

7. 4×10000uF capacitor 80-100V.

8. 3×Capacitor 0.1uF(104).

9. 1×LED 3 mm.

10. 1×Bridge rectifier GBJ2510.

11. 2×Fuse socket (10A).

12. 6×6.3 mm vertical PCB terminal.

Hello, I've made a 4-capacitor power supply board. This power supply provides ±70VDC, 15VDC, and 5VDC outputs. You can use this power supply up to 1500W amplifier.
