Just curious what would i have to do to make a usb power point from a 36v system? sorry to post technical questions in here but i am not allowed to post in the techie forum for some unknown reason

 

[rosjen]

You need a converter from 36 volts to 5 volts, preferably capable of supplying the standard 500 mA for a USB outlet.

These are an oddity and I can only find one at Powerstream in the USA at $30.75. Scroll down the page to the block of four DC/DC converters from 24 to 120 volts and click on the centre link. Then click on the 48 volt version numbered PST DAA 4805. This handles a 36 to 60 volt input for 5 volts output. On the second page of the buying process, make sure you scroll down a bit and select a lower price post option, the USPS Express option is what I use, about 12/15 days to delivery.

To wire the USB socket that you use to supply power from the converter[FONT=Arial, sans-serif], view the mouth of the socket where you plug in, with the four metal contacts above the plastic centre support, then the contacts are numbered 1 to 4 from left to right, so you wire to contacts 1 and 4.

[FONT=Arial, sans-serif]Contact 1 = +5v [/FONT]

[FONT=Arial, sans-serif]Contact 2 = USB - [/FONT] signal

[FONT=Arial, sans-serif]Contact 3 = USB + [/FONT] signal

[FONT=Arial, sans-serif]Contact 4 = - (Negative/ground)

Thanks flecc

Elaine I saw that already, seems you need to mount a dynamo - which would be wasteful on an ebike

Steady on Flecc you should know the (your age/2)+7 rule. She doesn't look 42 to me.

That calculation answer should be 44 Harry, I'm 74 this year.

Anyway, I'm rich enough to ignore that rule!
