The Bticino 346050 is a SELV-rated power supply for the Bticino 2 Wire door entry system, housed in a 6 DIN modular enclosure for rail mounting. It provides two SELV power supply outputs (one on TK BUS/IU BUS/SCS clamps, one on 1-2 clamps) which must be used alternately and not at the same time. Total maximum absorption across all outputs is 1.2A.

The 346050 has an integrated video adapter, eliminating the need for the separate 346830 module. It can also avoid the use of the A/V node F441 or Multi-channel Matrix F441M provided no more than three junctions are present (max 2 IU + 1 TK risers or 1 IU + max 2 TK risers). The unit can additionally serve as a standalone additional power supply via the 1-2 output. It is electronically protected against overload and short circuit - disconnect for 5 minutes after a fault event to allow automatic reset.

New, unused, old stock.
