Dual Rail Linear Regulated Power Supply Board Base on Sigma11
Before purchase please Note :
1. This SIGMA11 (Sigma) kit is only suitable for players with a certain electronic foundation and soldering iron soldering ability. If you do not have the ability to use it, please do not buy it.2. Due to different purchase batches, some components will be replaced without any notice under the guarantee of quality.3: PCB size: 100*75MM1.6mm1 OZ
4. When R10 is 10K, the output voltage is 23~24V (also the default output voltage of this kit), and the other is equipped with a 50K 3296 adjustment.5. The AC voltage supplied by the board should not exceed AC35V.6. For other output voltages, there is a rule of thumb that, under load, a voltage drop of approximately 8V-9V should be maintained through the mosfet.7:The rectifier diode can be insulated without insulation when it is used for heat dissipation. However, if the chassis is used for heat dissipation, it must be insulated (including the power supply adjustment Transistor).
10. For the convenience of the player, equipped with a 5V, 12V voltage regulator
11 This kit does not include the main filter electrolytic capacitors.
