| RiRaRi:
I want to get good 30V 5A programmable DC power supply and was looking at Sigilent 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 reccomend in this price range? |

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...... |

Thanks. Now i dont need extra channels. But in the other hand, it is not much more expensive so i might choose that one. I also heard that 3ch one is better built quality and has better IC inside. Is that true? |

A cheaper option is this one: Manson at 200€ https://www.reichelt.com/de/en/programmable-laboratory-power-supply-unit-with-usb-interface-hcs-3202-p106617.html It comes with its own proprietary software so you need to check that the software can do what you want it to do. |
