Description
Commodore 64 128 Stock Power Supply High Efficiency Low Noise 5V 9VAC C64 C128 PSU Replacement
It replaces the internal board with a high efficiency / current capability, low noise, fully protected buck regulator.
Works with 100~240V and 50/60 Hz transformers.
Double footprint to accomodate different diode bridges.
Nominal 5V output is adjustable up to 5.25V to compensate the power cord line drop (recommended 5.15V).
Thermal, under-voltage, over-current, short-circuit protections are available.
It also implements overload protections on AC lines (polyfuses).
(12V input, room temp)
95% efficiency @ 5.15V / 1.5A.
90% efficiency @ 5.15V / 4.0A.
Suitable for C64 (all models, + accessories, expansions) and C128.
