Ready.'s Commodore 64/128 heavy duty PSU
The specs:
- can run C128+1541-II or c64+1541-II and several other hardware such as REU, 1541-Ulitmate2, .... all together
- +5V line amperage exceeds 3A (3A garanteed, on the C128 version. 2A for the c64 version)
- +12V line amperage exceeds 1A
- 9VAC line max amperage 1A
- +5V and +12V are overvoltage, overload and shortcircuit protected (PSU self resets after power OFF in case of any event of these)
- overvoltage can be tested with a button by the user to make sure it works
- voltage ripple far below 50mV under all working conditions on 5V and 12V lines
- soft voltage rise/fall at start up/power off without overshoot/undershoot (gentle on electronics)
- fuse protected on the mains side with 500mA T (retarded fuse), which should blow only in case of big failure
- low pass filter and surge protection on the mains side to reject high frequencies and voltage spikes
- transformer with double insulation between primary and secondary circuits (grounding not required)
