Hi, I think a benchy psu would be very handy but can't spend too much on it. I found this one for which I also have a €10 discount code. Do you guys think this is good enough? https://www.eleshop.nl/0-30v-0-3a-labvoeding-met-verlicht-lcd.html Or should I go with a 5 amp one like this one? https://m.reichelt.nl/laboratoriumvoeding-0-30-v-0-5-a-gestabiliseerd-rnd-320-kd3005d-p212040.html?&trstct=pol_7 Or do you guys have better recommendations? Thanks. |

I suggest that you do some study, yourself, on power supplies. It is good etiquette. It is best that you develop the skills to do basic research. After that, we would be glad to help with any remaining questions. But, you certainly need some direction, to even know where to start. Factors to consider 1) Type of supply; Linear, or Switching. Each has its place. 2) Wattage needed; Depends on the type of work it will be used for. But, 30v and 3a is typical, of basic models. 3) Does it have course and fine adjustments? 4) Digital readout, or analog meters? 5) Does it have Constant Current and/or Constant Voltage? 3) Number of Outputs; Single, Double, Triple... 4) Quality 5) Budget Start with a search, within this forum. There are other threads on this subject. And, maybe look at some YouTube videos. Let us know, what you discover. Then, for any questions that you have, give us the details, of what you plan to do with it, etc. Don't be discouraged, we will help you. And, I was given this same advice, when I started posting here. It paid off. :-) |

You can buy it as 2nd or 3rd one and use for battery charging, etc. --- Quote ---Or should I go with a 5 amp one like this one? https://m.reichelt.nl/laboratoriumvoeding-0-30-v-0-5-a-gestabiliseerd-rnd-320-kd3005d-p212040.html?&trstct=pol_7 --- End quote --- Korad is quite ok for this money. It is digitally controlled (knobs are rotary encoders), linear power supply. There is also a version with more buttons/features (memory, output on/off, etc) available, KA3005. |

One thing both of the linked models seem to lack is an on/off switch for the output. That's a really handy feature, personally that's a must for me in a power supply. Reichelt actually has the better version of the Korad (KA3005P) on sale for ~€94 right now. I ordered one on Sunday, personally I would pay a little more to get that one. |

I use three of these: https://www.ebay.co.uk/i/183449223050?chn=ps 0V to 30V (you can never have too much voltage capability) 0A to 10A (you can never have too much current capability. Linear design, not switch mode Low noise output (10mV) Simple construction using basic circuitry Precision Voltage and Current coarse and fine controls Compact and fit on your bench without taking up too much room Sturdy construction Digital read out for voltage and current Silent until fan comes on automatically for high power demand, but then not too noisy. £50UK, but no doubt available in your country (you do not indicate where you are). Why go for anything else 8) |
