Compatibility & Buying Information
Exact Part Number: This page is for Mitel part number 50006822, identified by Mitel as the L6 48V North American AC adapter.
48V / 30W Output: The adapter provides 48VDC at up to 0.625A for a maximum output of 30 watts. Use it only with Mitel equipment designed for the applicable 48V local-power input.
North American Version: Part number 50006822 includes the power adapter and the appropriate North American AC power cord. Mitel lists separate regional adapter SKUs for other markets.
Universal AC Input: The switching adapter accepts 100-240VAC at 50-60Hz, but the included AC cord is intended for North American installations.
PoE Alternative: Many compatible Mitel 6800 and 6900-series phones can instead receive power from an IEEE 802.3af or 802.3at PoE-capable network connection. The 50006822 adapter is primarily needed when local power is preferred or when the connected network does not supply the required PoE.
6800 / 6900 Compatibility: Mitel's current engineering documentation recommends this 48V power-supply family for all 68xx, 69xx, and 69xxw IP phones, including supported configurations with programmable key modules and DECT accessories.
6700 Series: Selected legacy Mitel 6700-series phones also use 48V local power. Because the 6700 family contains multiple generations and models, confirm the exact phone's power requirements before ordering this adapter specifically for a legacy 6700 installation.
Adapter Label: Mitel notes that the physical adapter itself may carry internal part number 85900031. That number identifies the adapter hardware without a regional power cord and is not the normal customer-orderable SKU. Order 50006822 for the North American adapter package.
Not a PoE Injector: This product connects directly to a compatible phone's DC power input. It does not inject power into an Ethernet cable and should not be confused with a PoE injector.
Best Fit: Mitel 50006822 is best suited to compatible 6800, 6900, and 6900w-series phones that require local AC power because PoE is unavailable, as well as service inventories that need an official replacement or spare Mitel power supply.
