TMDSHVRESLLCKIT: About the specification of power supply

Genius 5840 points

Part Number: TMDSHVRESLLCKIT

Hello.

I would like to buy the external power supply as follows:

Could you tell me recommended power supply adapter or required specification?

・Voltage Input

・Voltage Output

・ID(mm)/OD(mm)

・Output Current

・Center Positive or not

Regards,

U-SK 

  • Hi U-SK,

    I looked at the BOM and the schematic for this design.

    I recommend the following for the auxiliary DC adapter:

    • Voltage input will need to be compatible with your mains voltage
    • Voltage output of 12-15VDC
    • Barrel plug ID(mm)/OD(mm): 2.10mm / 5.5mm
    • Output current greater than or equal to 500mA
    • Center positive

    Also note that there is a switch (M3-SW1) on the hardware that selects between an external 12V input from this adapter, or the 15V power from the onboard auxiliary supply.

    One more option is providing the 12V rail from a bench supply. The banana plugs BS3 and BS4 could be used for this purpose.

    Best,

    Clayton

  • Hi Clayton,

    Thank you for your reply.

    I understand.
