Commodore / Amiga / ZX Spectrum / Atari power supply unit (PSU) automated tester. Forces a constant current from the power supply and measures voltage levels and ripple. Results are displayed in real time on a digital OLED display. The tester features an aluminum heat sink to perform long-term tests.
Power supply failures are among the most common problems among retro systems. A PSU failure can lead to expensive repairs, or even render the entire system useless. This is specifically why we have designed the power supply tester. It runs a thorough test, minimizing the risk of damage due to an ageing factory power supply.
Measurement results are updated on a digital OLED display in real-time, allowing a live evaluation of the power quality.
Commodore C64 PSU TesterThe C64 PSU tester measures the primary +5V DC output voltage and ripple at a constant current of roughly 400mA...500mA. Secondary voltages (9V AC) are measured at a lower current, typically 50...150mA.
Commodore C128 PSU TesterThe C128 PSU tester measures the primary +5V DC output voltage and ripple at a constant current of roughly 400mA...500mA. Secondary voltages (9V AC) are measured at a lower current, typically 50...150mA.
Amiga 500 PSU TesterThe Amiga 500 tester measures the primary +5V DC output voltage and ripple at a constant current of roughly 400mA...500mA. Secondary voltages (+12V DC, -12V DC) are measured at a lower current, typically 50...150mA.
Commodore C64 + FDD 1541 PSU TesterThe C64 FDD 1541 Dual PSU tester measures the primary +5V DC output voltage and ripple at a constant current of roughly 400mA...500mA. Secondary voltages (9V AC, 12V DC) are measured at a lower current, typically 50...150mA.
ZX SpectrumC64 PSU TesterThe Sinclair ZX Spectrum tester measures the primary +5V DC output voltage and ripple at a constant current of roughly 400mA...500mA. Secondary voltages (+12V DC, -12V DC) are measured at a lower current, typically 50...150mA.
Atari XL/XEPSU TesterThe Atari XL/XE tester measures the primary +5V DC output voltage and ripple at a constant current of roughly 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.
