Posiflex 21972080139 12V 80W Power Adapter
Overview
The Posiflex 21972080139 is a 12V DC, 80W external power adapter designed as the standard power supply for Posiflex XT, KS, and TP terminal series. This adapter provides regulated 12V DC output at 80W capacity — sufficient for single-terminal deployments where wall-mounted or countertop mounting eliminates the need for in-UPS backup. The model 21972080139 is the factory default power supply for XT3815 and XT4015 systems, making it the direct replacement for OEM configurations.
Compatibility
This adapter is the default power supply for the following Posiflex terminal models: XT3815, XT4015, KS7717, KS7217, KS7215, TX3000, and TX4200. Verify your terminal's part number before ordering — the 21972080139 is specific to these XT, KS, and TP series devices and will not function with other terminal families. If you are replacing an existing adapter, match the voltage (12V) and wattage (80W) to your current configuration.
Installation Notes
This is a wall-mount external adapter with a DC barrel connector. Verify polarity and connector size match your terminal's power input before connecting. The adapter draws standard AC mains power — ensure the outlet is grounded and rated for continuous operation. No additional tools or configuration are required beyond a standard power outlet. The 80W rating assumes moderate ambient temperature; avoid placement in direct sunlight or enclosed spaces that could restrict airflow.
