voltage (i.e. 9vdc, 12vdc, 24vdc, 48vdc), and suitably rated output current (i.e. 100mA to

500mA).When connected to a 48 V centralized dc source these products shall be provided

with a Listed 5 A DC fuse in the supply circuit.

AC POWER SUPPLY ( using an external power adapter):

All models have an (8-15)VDC output with 6ft long cord

and a 2.5mm ve jack. The

power supplies are temperature rated to match the Media Converter Switch ratings.

Office Ratings (0 to 40°C)
North America models.

Input: wall plug, 12ovac at 60 Hz.

International models

. Input: 240vac at 50Hz with

IEC 320 connector for the user-supplied AC power cord.

Output:12vdc, 1Amps

Factory Floor Ratings (-25 to 60°C)
North America(-Hd) models.

Hardened, factory floor temperature rated. Input: 6ft AC

power cord to IEC 320 connector on the 100-240vac 47-63Hz external power adapter.
