The PD-64 from SideProjectsLab (SPL) is a compact plug & play power supply as a direct replacement for the original Commodore 64 power supply. The PD-64 is powered by a standard USB PD power supply (not included, but can be ordered as an option) and uses highly efficient switching regulators. This sets the PD-64 apart from other comparable switching power supplies: It not only provides the DC supply voltage (5 V DC \/ 2 A), but also a genuine, galvanically isolated AC voltage (9 V AC \/ 1 A, 50\/60 Hz) – thus replicating the original power supply unit completely and authentically. <\/p>\n

Both outputs are digitally controlled and equipped with a comprehensive protection circuit (electronic fuses, overvoltage and overcurrent protection, thermal shutdown). This ensures that the C64 is supplied with a stable and safe voltage at all times. <\/p>\n

Plug&Play – simply plug in and get started. No soldering, no modifications to the C64 required. <\/strong><\/p>\n

Functions & special features<\/h3>\n
    \n
  • Direct replacement for the original Commodore 64 power supply – no modification to the C64 necessary<\/li>\n
  • Genuine, galvanically isolated 9 V AC output voltage (not a simple DC substitute)<\/li>\n
  • Switchable between 50 Hz (PAL) and 60 Hz (NTSC) for the correct TOD clock (Time-of-Day)<\/li>\n
  • Highly efficient switching regulators on both outputs (5 V DC & 9 V AC)<\/li>\n
  • Digital regulation of both supply voltages for maximum stability<\/li>\n
  • Comprehensive protection circuit: electronic fuses, overvoltage protection, overcurrent protection, thermal protection<\/li>\n
  • Power Button Lock: controlled power-on process to protect the C64’s internal fuses<\/li>\n
  • Status LEDs show the status of both outputs at a glance<\/li>\n
  • USB-C input (USB-PD protocol, 12 V \/ min. 2 A required)<\/li>\n
  • DIN-7 connector for direct connection to the C64<\/li>\n
  • Compatible with all motherboard revisions of the Commodore 64 and Commodore 64c (including modern replicas)<\/li>\n<\/ul>\n
