This working model dynamo is mounted on a 200 x 125mm base plate, which also supports a 125mm diameter hand-driven pulley. The pulley is coupled, via a rubber belt, to a smaller pulley on the dynamo shaft, providing a step-up ratio of rotational speed. Electrical output is via a pair of 4mm sockets and a light emitting diode is provided as a simple output indicator. The model can also be used as a motor when connected to a 6 to 8V DC supply (not included). * Electrical output via 4mm terminals * LED output indicator * Can be used as a demonstration motor (requires 6 to 8V DC power supply) * Includes instruction manual * Eisco type PH1246 https://elecena.pl/product/27244110/eisco-demonstration-dynamo-hand-pulley 2024-11-12 https://elecena.pl/product/27244110/eisco-demonstration-dynamo-hand-pulley 2025-04-07 https://elecena.pl/product/27244110/eisco-demonstration-dynamo-hand-pulley 2025-05-25 https://elecena.pl/product/27244110/eisco-demonstration-dynamo-hand-pulley 2025-08-11
