Description
MagneTek F‑108U Power Transformer is an older product that has sat on our self a long time.
Briefly, it will accept 115 or 230V AC and convert it to24VAC – in the satellite world you may want external power for a LNA or LNB.
MagneTek’s “F‑series” control transformers followed a consistent pattern. Based on archived catalogs, the F‑108U most likely had:
- Primary voltage: 120 VAC (sometimes dual‑primary 120/240 VAC)
- Secondary voltage: 24 VAC
- VA rating: 20–40 VA (common for furnace control circuits)
- Frequency: 50/60 Hz
- Type: Foot‑mount or plate‑mount transformer
- Thermal protection: Internal fuse or thermal cutoff
- Class: UL Class 2
These values are inferred from MagneTek’s F‑series transformer line, which used similar numbering conventions.
