Title: Power supply Post by: tictoc21 on February 19, 2019, 07:34:50 PM Hi rc lovers
This is my new built 500watt bench top power supply made out of spare SMPS. The output voltages are, +12v at max 15 amp, +5v at max 20amps, + 3.3v at max 16 amp, -5 v at max 0.5amp, -12 v at max 0.3 amps Title: Re: Power supply Post by: K K Iyer on February 19, 2019, 08:55:16 PM Hi rc lovers This is my new built 500watt bench top power supply made out of spare SMPS. Interesting, but not quite clear! The output voltages are, +12v at max 15 amp, i.e, 180w +5v at max 20amps, i.e, 100w + 3.3v at max 16 amp, i.e, 53w -5 v at max 0.5amp, ??? -12 v at max 0.3 amps ??? Title: Re: Power supply Post by: tictoc21 on February 19, 2019, 09:50:03 PM 12v ×14 amp = 168 watt x 2 outputs= 336 watt ( see 3rd pic)
5× 20 amp = 100 watt 3.3v × 16 amp = 52.8 watt -5 v × - 0.5 amp = 2.5 watt -12 v × - 0.3 amp = 3.6 watt Total 494.9 watt Title: Re: Power supply Post by: Balakrishna Reddy on February 19, 2019, 11:28:31 PM 12V rail has two outputs?
You mean you have put two SMPS components in one box? BTW can you post ratings of SMPS itself. Title: Re: Power supply Post by: tictoc21 on February 20, 2019, 12:05:32 AM This is it!
