UCF-3.1 Universal Modem housing
The UCF-3.1 is a housing for 19″ cabinet mounting.
It is suitable for MuLogic products like the LLM-336R and LLM-336R.Eth card sets.
The modem and interface cards interconnect inside the UCF-3.1 housing.
The housing therefore has no back plane: all connections, including the power, are made externally.
The UCF-3.1 has no internal back plane: all connections, including the power, are made externally.
The screw terminal sockets (2 per panel), allow for a very flexible power supply arrangement such as “daisy chaining”, feeding from different sources, looping etc.
All MuLogic rack cards can be powered directly from 9..36Vdc (10..28Vac) or 18..60Vdc sources.
If these voltages are not available, external mains power supplies can be used (e.g. power adapters, DIN-rail mounted PSUs or AC transformers).
