    0-30 Vdc Stabilized Power Supply

    Hello everyone! I'm going to make this very nice power supply, mainly after lot of modifications to improve its quality! I was thinking if is possible to use a 15+15 VAC xformer... but with a relay to switch beetween 15Vac or 30Vac to feed the AC input and keep it away from excessive heat...

    Re: 0-24V/0-5A Lab Power Supply

    Pretty nice project ! What you use to make the indicators ? (voltage and current) ICL7107 ? Could you share the gerber of your board ? I was thinking about make the 0-30v 3A project, but after see yours... I change my mind ! going to make your design. Thanks alot !

    0-30V Stabilized Power Supply

    But I can't just use 24VAC and get a maximum output of 25VDC ? I'll need to make modifications to the circuit ? thanks !

    0-30V Stabilized Power Supply

    AudioGuru, I'm going to make the circuit of this thread (posted by Redwire and your partlist with red comments) is this ok ? My transformer is 12+12VAC How much current can I drive of each output transistor ? thanks Marcelo

    0-30V Stabilized Power Supply

    Hello Guys ! I have a 24Vac x 25A transformer... What I need to make to have more than 0-3A at output ? Let's say 0-5A How much DC regulated can I expect with 24Vac at input ? I'll make two boards and have a dual output power supply... there is a lot of "Amps" from my xformer :) Thank you!
