I am in need of a 80v buck converter that is adjustable rated 4 amps or better
Can anyone recommend a switching regulator or a buck converter that has these specifications
Input voltage 80 adjustable at least 4 amps or better Any information would greatly appreciated Thanks

Re: I am in need of a 80 buck converter that is adjustable rated 4 amps or better
What is the highest input Voltage do you need?
Is the 80VDC the minimum input Voltage?

Re: I am in need of a 80 buck converter that is adjustable rated 4 amps or better
From what I have seen when turning the power supply on that this voltage stabilizes at 70 to 75 volts and stay at this level until it is loaded and at 3.5 amps it is about 50 volts or so this is also stable
I would like to have some head room above the maximum voltage that I have seen so far |

What are the specs you are looking for? >80VDC 4A in, 50VDC 4A out?

But what I am really interested in is an adjustable output voltage at minimum of 4 amps Last edited by sam_sam_sam; 02-28-2021 at 06:20 AM.. |

Would this work

Re: I am in need of a 80 buck converter that is adjustable rated 4 amps or better
Is this for powering that big solenoid? Does it have a reverse-diode across it?
The raw DC is from a control transformer feeding a bridge-rectifier with no filter capacitor? Just trying to get clear on what the load and input power is. Because any buck-converter will not like input ripple. |

I found this and this would work also https://www.ebay.com/itm/FNIRSI-DC60...kAAOSwF5dfhtrW The only thing I have to figure out is how to make sure that the incoming voltage does not exceed 70 volts because I was looking earlier for a Zener diode to limit the voltage to 60 to 80 volts and could not find anything I could use Thanks Last edited by sam_sam_sam; 02-28-2021 at 03:39 PM.. |

Re: I am in need of a 80 buck converter that is adjustable rated 4 amps or better
Not adjustable but you may be able to modify the feedback circuit.
What is the adjustable range? https://www.amazon.com/Pro-Chaser-re.../ref=pd_sbs_4? https://www.amazon.com/High-Voltage-.../ref=pd_sbs_1? |
