    Variable Power Supply 0-24vdc 5A more...

    mihpa, I have built this circuit and it works fine. To feed this circuit you need a transformer (28V 8A) and a rectifier (20A). It is not necessary to stabilise this. Yes you can adjust the output voltage 2.5

    Led Strobe Circuit

    vainajala, They will have a very short life with 2A, a few seconds perhaps! It better not happen with the most expensive LED:s. :o Ante ::)

    Switching power supply

    vainajala, Then I would change the TIP 32A for a MJ 4502 or similar. The inductor and diode should be higher rated (10A+) and the voltage and current feedback resistors changed to give you the desired output. A bit larger caps is necessary and remember heavy wiring for the input / output path...

    Switching power supply

    vainajala, Welcome to this community. When rectifying and filtering 32VAC you end up with about 50VDC and this is to much for the TL494. Ante ::)

    UPS Question..

    Rhonn, The voltage at the bases can be adjusted between 6.5 to 11.5 volts if my calculations are right. The voltage at the collectors is about 25V, does this make any sense to you? The output will not charge a 12V battery, or am I missing something? Ante ::)
