I want to get good 30V 5A programmable DC power supply and was looking at Siglent SPD1305X and Rigol DP711. These two have low noise and are linear which is very good since i deal with solid state radios. Which one would you recommend in this price range?
Knowing the Siglent PSU's quite well I would spend a little more for the 3ch SPD3303X-E and use it in Parallel channel mode for its 6A capability and in Serial mode for 60V capability.
Should you need more, several units can be placed in series for elevated voltages.
We do sell the odd 1305X but many more SPD3303X-E.
Then there are the hacks......
