Very frustrated. No matter how I arrange test leads, I cannot get any voltage out of the 15v side. So, for now, everything got chucked into a box that say "F--- It For Now" If anyone wants to offer to wire this little demon for me, I pay $20 plus shipping. I've had it with the cooling fan!!

I read you all hard time and waste time and figure...
you need a simples small package about 9 volts battery size
a smallest power transistor only easier hook five wire.....
Package is 4.5 x 1.5 x 2.5 cm ( 1.75 x 7/16 x 1.0 inches )
36 volts *(28-42v input => 12v 5% Volts output at 2 amp)
Thanks Craig, That is exactly what I am getting. But, dumb me couldn't even wire that correctly. I just don't get the wiring thing for some reason. Chas. Stevenson volunteered to do the wiring for me. Thanks for the input. Down the road, I may get a 48v controller from you to take this project to the last (and fast) level!
Bob, I have a similar dc-dc and I just skipped wiring the pot in and let the blower run at 15v. It blows a little harder.
I also hard wired the switch input to the dc-dc and have it switched by the main relay that runs the controller.
Thanks Fechter. Care to say that in pictures? :)
The Lucent JW030C1-M DC-DC Power Module Spec Sheet was a fileshare, and has been removed. If you still need it, I can send it to you or Fechter. We're in the process now of placing all of the fileshares, as well as the Help Tutorials where they will be easily accessible.

here specific sheet for Lucent JW030C1-M DC-DC Power Module Spec Sheet
i have scanned and send you a file to here ...... :jawdrop: :jawdrop: :jawdrop: :jawdrop: :jawdrop:
================ here is Simples hook up ==================
Deafscooter is Here...
I have one of best on 30v~60v input into 12v=8A
Here is Picture, That Craig have many of them From China's Large E-Scooter
Thanks Craig, I have one question on your drawing. What is the wire off the (-)sen terminal? Is it grounded to the frame?
FWIW, here is the
Lucent JW030C1-M DC-DC Power Module Spec Sheet again if you need it.

Sorry for not keeping up on the thread Bob,
I'd recommend hooking it up like this:
I'm just not sure about the switch connection since I can't seem to view the datasheet.
My Bad, the Lucent JW030C1-M DC-DC Power Module Spec Sheet link should be working now.
There is a lot of moving around right now trying to repair all the broken fileshare links.
OK, from the spec sheet, I can see that Chas had it right. You can use it either with or without the trim pot.
Without the pot, it looks like this:
If you have a pile of fixed resistors lying around, you could try various values between the trim pin and the output to lower the voltage if you want. Fixed resistors are much smaller and can fit right between the pins. The blower should be fine with 15v though.
I did the same thing you did the first time. If you look back at this thread I also had the on/off wire going to the positive then I read the spec sheet and noticed it had to go to the negative side of the power. Thanks for the conformation however. I have 5 of these and plan to pre-wire them for others to use. I plan to keep 1 and Bob gets 1, that leaves 3 for whoever.

Chas, this is Whoever, I only need you to save one for me. First I need to figure out what it does, and if I need one. That's the way we Pack Rats operate.
When I start running with the Big Dogs, I'll probably need something like that.
O.K. Gman, Now there are 2 left.
BTW did I tell you the price is $25.00 plus shipping.
As for what it does it converts your 36 to 75 volt battery voltage to a 12 volt output to be used for accessories, like charging your cell phone or running lights. I'm not sure how much it can be adjusted, I'll find out when I build one.
Here are a couple of pictures of how I installed a switch for my blower. Made from copper flashing.
And finally, many, many thanks to all that gave me suggestions. But, especially to Chas S. for doing the actual wiring for me "Gratis". If it weren't for this forum, I'd have a pile of nice looking heavy push scooters
Very nicely done. I will have to remember that idea for switch mounting, it's very functional and clean.
P.S. Glad I could help. ;)
For those of you who are wondering here is the know working wiring diagram, which may also be found in the EV DownLoad Library.
This is how I wired the ones Bob and I are using and they work well.
I take it the voltage adjust is because the individual DC-DC might not be producing exactly 12v and the adjustment is to get it on the mark?

That is correct, this unit is designed to be adjustable. If you do not add the adjustment pot the output is fixed at 15VDC.
Just checking in to see how the DC to DC converter is holding up for you. Hope all is well.
Just perfect. And I haven't forgotten that I promised to send you my unit that I accidentally arced. I have it all ready to pack and ship. This should get me to the post office!
