    35 Ampere power supply Board

    Features of Unicornis Power Supply Board

    • High Output Current -  35 Ampere, Capacitor Dia Ø 30mm max.
    • Unregulated power supply - Capable of  delivering high peak currents with low ripple as demanded by Amplifiers.
    •  Amplifier usability - Designed for High power audio amplifiers.
    • Advanced Features - Dual Reservoir or Pi Filter capable supply.
    •  Protection devices - fuses are provided on each supply rail for preventing burnout in case of fault or short circuit.  
    • Standard Components - standard branded components which are available online or at your local electronics store.
    •  No SMD components used - only through hole components are used in the pcb, this makes soldering and replacement of components hassle free. 
    • Metal Tab Connectors or Screw Terminals - Metal Tab Connectors or Screw Terminal of 5mm pitch can be used at input and output to handle High Currents.


    How the Audio Power supply circuit works - Brief description

                                                                                 Click Here to download 35 ampere power supply circuit diagram 


    This power supply is designed for Hi fi Audio applications.


    C1 & C2 capacitors to filter higher frequency noise from the transformer

    secondary AC lines at the diode bridge.


    AC input received from transformer is converted in to DC by Bridge rectifier D1. 

    Always use heatsink with bridge rectifier because without heatsink the bridge rectifier will gets hot.

    So use suitable heatsink to get full output current from the bridge rectifier.


    C3, C4, C5 & C6 are in parallel with the bridge diodes to reduce high frequency noise and ringing of the diode.


    C7 & C8 capacitors to filter higher frequency noise right at the DC output of

    the diode bridge.


    C9, C10, C11 & C12 are the large reservoir capacitors to supply large current demands and stabilize the supply rails to minimize low frequency fluctuations.


    C13 with R1 & C14 with R2 are to decouple the large electrolytic capacitors and reduce

    impedance.


    C15 & C16 are Film capacitors to filter high frequency Noise.


    LED D2 with R3 & LED D3 with R4 are to indicate supply status.


    JP1 & JP2 are Wire Jumpers of Copper wire of Suitable Gauge.


    As we can see in the circuit diagram, C9 and C11 is separated by jumper JP1, C10 and C12 is separated by JP2. in normal case a simple wire connector is sufficient. 


    Advanced Features -


    • Dual Reservoir - We can use 0E22 5 / 10 Watt wire-wound resistor in place of JP1 & JP2, it will further reduce the ripple at output as C9, C11 & C10, C12 will work as dual reservoirs. this is a very cost effective method of reducing ripple.


    • Pi Filter - using 10mH inductors of suitable wire gauge in place of JP1 & JP2 will provide best ripple rejection and very clean DC. wire gauge of inductors or we can say their current capability depends on the load current. More the load, Bigger the inductor ( some times as big as the main transformer ).
