Citizen 36AD3-U AC Adapter with Power Cord

Overview

The Citizen 36AD3-U is a direct-fit AC power adapter with integrated power cord designed for Citizen's CT-S6XX and CT-S8XX thermal receipt and label printer series. This accessory delivers stable AC-to-DC conversion for field deployments, replacements, or secondary printer setups where the original supply has failed or become unavailable. The 36AD3-U is a factory-new genuine component sourced direct from the manufacturer, ensuring compatibility and reliability across the supported printer families.

Compatibility

This adapter is engineered specifically for the Citizen CT-S6XX series (CT-S601, CT-S603, CT-S605, CT-S651) and CT-S8XX series (CT-S801, CT-S851) thermal printers. Do not use this adapter with other Citizen printer models or non-Citizen hardware — cross-compatibility risks printer damage or power supply failure. Verify your printer model number before ordering to confirm correct fit.

Installation Notes

Connect the barrel connector firmly into the printer's power input port until you hear a click or feel firm seating — a loose connection will cause intermittent power loss or failure to boot. Route the power cord away from thermal print heads and moving mechanical parts to avoid damage from heat or abrasion. Use a standard grounded wall outlet (120V or 240V AC, depending on regional supply); do not connect through unregulated power strips or daisy-chained adapters. Allow 30 seconds after power connection before the printer begins self-test.
