• Electrical output via 4mm terminals
• Hand powered
• May also be a motor powered by 6 to 8V power supply

This model is mounted on a base plate 200 x 125 mm approx. which also carries a hand-drive pulley 125 mm diameter coupled to the smaller dynamo pulley by a rubber belt to give a step-up ratio. Electrical output is via a pair of 4mm sockets and a light emitting diode is provided as simple output indicator. The model may also be used as a motor on 6 - 8 V DC supply.
