Cisco 341-100594-01 48V 1.042A 50W AC Adapter for 8800 Series IP Phones

Product Description

Cisco 341-100594-01 48V 1.042A 50W AC/DC Power Adapter is a genuine Cisco external power supply used with compatible Cisco enterprise IP phones and other supported Cisco equipment requiring 48V DC power.

The adapter accepts 100–240VAC, 50–60Hz input at up to 1.2A and provides a regulated 48V DC output at 1.042A, delivering approximately 50 watts of power.

Cisco documentation identifies P/N 341-100594-01 as a compatible Power Cube 4 adapter for Cisco 8800-series IP phones including models such as 8811, 8841, 8845, 8851 and 8861, depending on deployment and accessory requirements. Cisco

This adapter is suitable as a replacement for a missing or failed original Cisco power supply, or as a spare for compatible Cisco phone installations.

There are also third-party and secondary-market references that associate the same Cisco part number / 48V 1.042A power architecture with Aironet 2800 / 3800 series access points and Cisco Cius Media Station; however, because Cisco’s phone documentation provides the strongest direct confirmation, I would keep those as secondary compatibility terms rather than making them the main title claim.
