These 24V operated units are suitable for use on board large locos above O gauge size.
The engine noise effect is directly linked to track or regulator voltage, and varies from a rhythmic idle sound when the loco is at rest, to a full-bodied "roar" when the engine is in motion, with turbo "whine" if required. The idle speed is fully adjustable, as are maximum revs., turbo level, cylinder level, tone and volume.
Module size (L x W x H): 115 x 70 x 42mm.
24V dc operated, for ride-on locos using 24 volt battery supplies (2 x 12V). Approx. 5 watts power output, and 112 x 112 mm speaker (one more can be added in parallel for extra volume, cat. no SP3).
