## Facts

- **LLM-F20**, **LLM-F30**, and **LLM-F50** LabelMark optical-fibre markers (default 220×220 mm lens, carton) share a barebone and are interchangeable. Finished machines are not always in stock; convert by swapping the laser source, and the 24 V PSU only if the one already in the unit cannot cover the new source.
- **LLM-F20** = barebone + **LF-20** (20 W pulsed source, 2 m fibre, head; 24 VDC 7 A) + **AE-POWER/24/10** (220 V in, 24 V 10 A out; up to 30 W fibre marker).
- **LLM-F30** = barebone + **LF-30** (30 W; 24 VDC 10 A) + **AE-POWER/24/10**.
- **LLM-F50** = barebone + **LF-50** (50 W; 24 VDC 14 A) + **AE-POWER/24/17** (24 V 17 A; up to 50 W fibre marker).
- 20 W → 30 W: change the laser power source only.
- Step up to 50 W: also change the 24 V DC supply unless the installed PSU is already large enough for the source draw.
