Heya folks. I need some advice on protecting my power supply from accidental shorting.
Here's the situation:
I built a multi-output power supply, which is basically 3 different power supplys which run independantly, stuffed into a single enclosure. The outputs are:
1. Regulated 5VDC positive and negative
2. Regulated variable output (both positive and negative)
3. Regulated 12VDC
The supplies will only be capable of about 1.5 amps for each output.
The voltage output is fed to a 7 segment display which is driven by a ICL7107 in order to display the output voltage and amperage.
Currently, there are 2A fuses in between the mains and the transformers. (3 fuses, 3 transformers)
Now, the power supply is a prototype of a PS that will be used by students. With that said, there may be accidental shorting of the output leads from the power supply.
Are the mains fuses capable of protecting the entire circuit from these probable shorts? If not, what is the best way to protect the power supply from accidental output lead shorting?
I appreciate your time, and any assistance that you may provide.
