Plantronics 9V 500mA Power Adapter

This Plantronics SSA-5W-090050 adapter supplies 9 volts at 500 milliamps to compatible headset bases. It serves as a direct replacement for lost or damaged original units. The unit is new and finished in black.

Fixed 9V Output Limitation

The adapter delivers a fixed 9V output at 500mA and cannot adjust voltage or current for other devices. It uses a proprietary connector sized for the listed Plantronics models only. Polarity and tip dimensions are not interchangeable with generic barrel plugs.

Powers Listed Headset Bases

The 4.5-watt capacity comfortably runs Plantronics S11, S12, CT11, CT12, CT14, T20, CS540 and W740 bases. It will not support devices that require higher current or a different voltage. Buyers needing to power multiple bases simultaneously or units with different power ratings cannot use this adapter.
