i dont have time to build another one, or to repair my damaged recently built one SMPS. the earlier one with CC feature havent been completed, so i got fed up... enough rant... now i need a lab PSU quick, please recommend me to buy one thats is bang for buck, search in eevblog doesnt give specific what i need, mostly linear, or low power version. here is what i need...
i dont need super low noise output, but the lowest noise figure will help. i need high power because i'm thinking to power motors and power resistors with it etc, along with supplying low power digital circuit such as mcu etc which i can provide local low noise linear regulator to them such as 78L05, LM317 etc if i need low noise. so this calls for SMPS version PSU, lightness of it will give merit. spec is somewhere like 1V - 60V give or take, it can be 3-40V etc if 1-60V is not available in the market. the lowest the low volt range is better, the biggest volt for high range is better. amperage is preferably up to tens of ampere, maybe 30-60A? but if price too much, i can tolerate lower 10-20A. budget is somewhere from $0 - $500 (i dont mind 2nd hand as long as its working), constant current limit is much much much preferable. i dont need fancy constant power or constant resistance etc, only current limit and constant voltage (normal mode) will do. so basically the spec is like below (not very strict, i can tolerate a little bit of lower spec)
1-60V low - 30V range
30A max (preferably throughout voltage range)
CL, CV mode only.
larger spec at the budget will be golden. Thank you...
edit: more than one floated output in one unit is preferable so i can save lab space.
