The Cisco 341-0502-01, manufactured by LiteOn, is a dual-output external AC/DC power adapter that provides 53.5V at 1.55A and 12V at 3.5A through a 4-pin connector. It is commonly used to power specific Cisco routers, wireless controllers, access points, and certain service modules that require this unique voltage combination.

This compact yet powerful brick-style adapter converts standard 100-240V AC input into two regulated DC outputs (53.5V for PoE or main power and 12V for auxiliary electronics). It is an official Cisco spare part, often referenced under the alternate part number 341-100399-01. The adapter is widely used with Cisco ISR series routers, Aironet wireless controllers, and some Catalyst or ASR components that do not use standard internal PSUs.

• Dual-output design: 12V @ 3.5A (main system power) + 53.5V @ 1.55A (PoE rail)
• Total power: 125W (combined output)
• Universal AC input: 100–240V, 50/60 Hz
• 4-pin proprietary DC output connector (splits to router + PoE)
• Active PFC for reduced harmonics and better efficiency
• Over-current, over-voltage, over-temperature, short-circuit protection
• Status LED for power/fault indication
