Gigabit converter with PoE PSE (30W, 24/48VDC)



Unmanaged Gigabit Ethernet media PoE+ converter that  acts as 30W PSE which may be powered from 24/48V supplies.

  • 10/100/1000Base-T and optical 1000Base-X Ethernet conversion
  • PSE (Power Source Equipment) provides 30W PoE+/PoE power over Ethernet
  • Supports dual rate (100/1000) SFP
  • DIP-Switch to set functions
  • IP30 rugged metal housing and fanless
  • Wide operating temperature -20~75°C
  • Supports Jumbo frame 9K bytes packet


IMC-1000S-PH12 is a family of unmanaged Gigabit Ethernet media converters that support conversion between electrical 10/100/1000Base-T and optical 1000Base-X Ethernet and as PSE (Power Source Equipment) provides PoE+/PoE power over Ethernet. The IMC-1000S-PH12 utilizes an SFP cage for 100/1000Base-X compatible SFP modules. Housed in rugged DIN rail or wall mountable enclosures, these converters are designed for harsh environments, such as industrial networking, intelligent transportation systems (ITS) and are also suitable for many military and utility market applications where environmental conditions exceed commercial product specifications.

Power Boost

Power Boost technology means that these units do not require special PSU's to deliver 50V regulated power to PD's (Powered Devices).  They have high effiency inverters which means they can be powered from standard 24 or 48V DC supplies.
