I'm awaiting guidance from mods as to where to post this question but i'm looking for help asap so hoping some kind soul can help me out. I am aware this has likely been answered many times so apologies for duplication.
1. I have a wind turbine whose output I am testing.
2. I am using a data logging device that measures voltage of between 0-30v.
3. The wind turbine, is frequently generating more than 30v.
4. I need to build an overvoltage circuit that will protect the data logging instrument when the voltage goes above 30v, though realistically the cap could be between 24-30v for the purpose of my research.
5. I'm thinking zener diode is the way to go, with or without a fuse.
6. It's likely that at 30v+ the turbine is generating somewhere around 10a (guesstimate)
So my questions:
1. What wattage diode would I need, would 300w be sufficient? What would happen if the voltages go over eg: 400w?
2. Do I need a fuse and if so what size?
Many thanks for any help/direction.
