Usage Instructions
Small hand crank generator is mainly used for charging small batteries. Therefore, the generator needs to convert AC to DC, requiring rectification and filtering. The circuit diagram is as follows:
F: Generator, where the three output wires can be connected to diodes (D) in any order, regardless of phase.
D: Diode, recommended model 1N4001.
C: Capacitor, with a capacity range of 470μF to 2000μF and a voltage rating of 50V.
After rectification, the DC output voltage is higher than the AC output voltage. The DC voltage is approximately 1.3 times the AC voltage. For example, if the unloaded AC output voltage is 8V, the corresponding DC output voltage will be around 10.4V.
