Quick PSU diagnostics

Power supply failures are among the most common problems among all retro computer systems. Our power supply tester series for Commodore C64, C128, Amiga 500/500+/600/1200, Atari XL/XE, and ZX Spectrum +2A/+2B/+3 was created specifically to address this issue. Diagnosing a PSU failure can prevent expensive repairs or even save your hardware from a total damage. The power supply tester runs an automatic yet thorough test, measuring currents, voltages, and even voltage ripple.

Características

• Automatic testing for C64, C128, Amiga, Atari, ZX Spectrum PSU families
• Forces a constant current from the 5V, and 9V or +/-12V PSU outputs (depending on version)
• Measures voltages, currents, and ripple
• Results displayed in real-time on digital OLED display
• Heat sink for dissipating power during long-term tests
• Plug and play easy usage, no setup required

Check it before it's too late

Power supply failures are among the most common problems among all retro computer systems. Our power supply tester series for Commodore C64, C128, Amiga 500/500+/600/1200, Atari XL/XE, and ZX Spectrum +2A/+2B/+3 was created specifically to address this issue. Diagnosing a PSU failure can prevent expensive repairs or even save your hardware from a total damage. The power supply tester runs an automatic yet thorough test, measuring currents, voltages, and even voltage ripple.

How it works

The C64 PSU tester measures the primary +5V DC output voltage and ripple at a constant current of roughly 400mA...500mA. Secondary voltages (9V AC or +/-12V DC depending on the model) are measured at a lower current, typically 50...150mA. Measurement results are updated on a digital OLED display in real-time, allowing a live evaluation of the power quality.

Long-term testing

The power supply tester has an aluminum heat-sink allowing to dissipate excessive power and perform long-term testing. It's designed to work both as a quick diagnostic tool, and for long-term stability tests.

Perfect match

Our power supply testers are a perfect match for our retro C64, C128, Amiga, Atari and ZX Spectrum power supply series. Our C64 PSU and Amiga PSU design are well established architectures, produced and sold in hundreds of units monthly. Both series are designed to be mutually complementary.
