Hello Sika and Alex, I'm looking for a hum free bipolar/dual power supply about +- 28V 2A. Could you comment on ripple/hum of your Raw DC Board? Thank you very much. - Jos
Hi, first sorry for late answer 🙂.
Regarding hum free request, look, CRC filter is CRC filter, you will get same filtering regardless of PCB used, only important is CRC values and quality of components used.
I believe there are calculator on forum for calculating PS performance with defined values.
Streghth of this board is (IMO):
- Minimized EM interference, achived with routing ala twisted pair.
- Layout is very flexible, you can use parts (rectifier diodes, capacitors) of different types, look at the PCB for details
- Price is very good IMO (25$ for 10 pieces (cca) shipping included)
- Manufacturing is realy well.
Use Duncan Power Supply calculator to see what values of caps and resistors will give you desired output.
