Citizen 35AD2-U AC Adapter
Overview
The Citizen 35AD2-U is an AC power adapter designed to supply the Citizen CT-S310 thermal receipt printer and related PPU power supply modules. This adapter bridges wall outlet power to the printer's internal power management system, replacing OEM units that fail or wear out. Use it when the original power supply has degraded or when provisioning a replacement unit in the field.
Compatibility
The 35AD2-U is engineered for the following Citizen products: CT-S310 compact thermal receipt printer, PPU-700 external power supply unit, and PPU-231 power management module. Do not use with other Citizen printer series or third-party equipment — connector and voltage specifications are proprietary to these models.
Installation Notes
Connect the adapter output directly to the printer or power supply unit's input port. Ensure the wall outlet is grounded and rated for the adapter's input specifications. Verify the output connector seats fully before powering on. Keep the adapter away from moisture and direct water spray to maintain safe operation. If the adapter fails to deliver power or shows visible damage to the cord or connector, do not attempt repair — replace with a factory-new unit sourced directly from the manufacturer or channel partner.
