Hi,

quick question... when I add the resistors as on your pictures... will it work? Or should be modified somehow the software?

Thank you for clarification

If you set the power supply output voltage to 14.4V, use resistor values as follows: OVP1: approximately 17k, OVP2: 22k, OUTPUT: 22k. If you set the power supply output voltage to 14V, use resistor values as follows: OVP1: 22k, OVP2: 28k, OUTPUT: 28k. Attention: Please note that the resistor paralleled with OVP1 is prone to lifting pads during soldering. Therefore, replacing it with a 0603-size resistor would make soldering easier.

thank you for answer... I need something about 14,8V. On my shop floor is present hot air gun and special equipment... I prepared OVP1 12K OVP2 22K and Output 22K is that correct? which formula to use for calculation?

[darwinbeing]

To achieve a 14.8V output with the resistor values OVP1 ~ 15.5kΩ OVP2 ~ 19.2kΩ OUTPUT ~ 19.2kΩ

I am just preparing components... and thinking.. do you mean to replace whole resistor placed on board for OVP1 17k?? when I replace it, will it be OK? I found only 16,9K 0603 resistor...

concider that 14,4V will be good enough for me

[darwinbeing]

Yes, both options should work. You can either parallel another resistor to achieve a value close to 16.9k, or you can replace it with a 3k 0603 resistor.
