C64 FDD Dual PSU Tester - Commodore 64 + FDD 1541-II Power Supply Tester

Description

C64 FDD Dual PSU Tester
C64 FDD Dual PSU Tester - Commodore 64 + FDD 1541-II Power Supply Tester, Measures Voltages, Currents, Ripple, OLED Digital Display
Commodore 64 power supply unit (PSU) automated tester with an additional input for an FDD 1541-II/1571-II/1581 power supply. 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. Round DIN7 and DIN4 plugs matching the original C64 PSU and FDD PSU pinout.

Check it before it's too late
Power supply failures are among the most common problems among retro Commodore 64/128 systems. A C64 PSU failure can lead to expensive repairs, or even render the entire system useless. This is specifically why we have designed the C64 power supply tester. It runs a thorough test, minimizing the risk of damage due to an ageing factory power supply.
Voltage, current, ripple
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, 12V DC) 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.
Dual power supply
The C64 FDD Dual PSU tester has an additional DIN4 input for testing an FDD 1541-II/1571-II/1581 in parallel. The screen will cycle through measurement results performed on both power supplies.
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.
