Protect Your Hardware with a Modern Sinclair QL Power supply replacement / Converter
The original Sinclair QL “brick” was a marvel of 1984 engineering, but by today’s standards, it’s a liability. This modern, custom-designed QL Power Converter replaces the ageing AC/DC internal components of the original with modern, efficient circuitry.
Why Upgrade Your QL PSU?
- Cool Operation: Modern switching technology means this unit barely gets warm, unlike the original which acts like a room heater.
- Component Safety: Provides stable, ripple-free power to protect your sensitive ZX8301 and ZX8302 chips.
- Compact Design: Much smaller and lighter than the original, making your desk setup cleaner and more portable.
- Plug & Play: Specifically terminated for the Sinclair QL’s unique power socket—no modifications required.
- Ease of use: A power ON/standby switch is provided which means the converter can be left plugged into the QL – no more pulling the plug to power down the QL
- Protection: Protection is provided with the converter returning to standby if excessive power draw is detected, or if the external power supply is of insufficient power rating.
Technical Specifications:
- Input: 12V input from a customer supplied power supply (plug pack or other suitable power source with a 2.1mm DC plug – either positive or negative centre contact.)
- Output: converts this single voltage into the DC and AC voltages the QL requires.
Build: Housed in a durable, custom 3D printed enclosure designed for long-term use.
