[GreenKeys] Fusing Requirements for Loop (Model 26)?

[Ralph Mowery]

They are easy to find if you know what  to look for.

 

Look for PICO fuses.  There are plenty on ebay.  Here is some 125 ma which is probably what you may want to start at.  If you try using some 60 some ma fuses they will probably blow like popcorn.

Here are you r American brand name 63 ma fuses if you insist in trying.

Here are some rated for 250 volts

I'm going to be setting up my model 26 with a laptop power supply, eBay boost converter (boost to 97v) resistor for my loop supply (60mA) and the usb/tty board (Thanks Jordan!) 

 

I'm trying to find a good supply of the 63mA dc fuses to run this, I'm not trying to burn up my magnet, and don't really know if say 100mA fuse would work or if the magnets are so delicate that I should just keep looking for that "right" fuse. 

 

DC fuses are as in previous conversations, a pain to find and not nearly as plentiful as the blade fuses or glass fuses.

 

 

Thanks,
