wouldn't be the first time i bought a product that has been discontinued. the other issue is not being certified by canadian version of UL if i understand it correctly, not something i'm worried about at all being south of the canadian border.
the cost was comparable to the power adapter i was looking at so it's an acceptable level of risk for me.

I have ran mine off of my checkpoint charger many times. I use the motor check mode at 7 volts.

brief update. both the tire truer, power supply and ec3 connectors arrived so i took care of all those little bits today.
the ec3 connectors are easy to install.
i saved the gator clips and reused them just in case. made a connection cable with banana plugs as well so i'm covered.

Did you get the hudy adapter. If so you will want to try and get a hold of a pn one. The hudy does not spin the tire true. Just watch it and you will see the wheel wobble.

turned it all on today and discovered the adjustable power supply isn't so adjustable. the effective ranged is limited to 11.9v to 16v. even at 11.9v the tires heat up quickly. i was hoping to start at 5v and work up from there to a sweet spot.
looks like i will have to continue searching...

well, for those that commonly run at 12v, this power supply is both cheap and provides a digital readout on the output. it just happens to run at a bit higher range than i was hoping for. i still think it's nice but i'll still be looking for something within the 5-12v range.

ok, i've kept up my search and run across some things on ebay that look promising but i don't fully understand the function of the devices. i'm not proficient in electrical engineering so please excuse my lack of knowledge in this area.
item number: 400521278194
3~35V to 3.5~35V 100W Adjustable DC-DC Step-up Boost Voltage Converter Module
i assume that DC-DC in the title means it will not serve my purpose of converting AC to DC. the information isn't the best on this listing but that seems fairly self explanatory.
item number: 121056548481
1.5V - 40V/ 5A adjustable regulated Linear Power supply Transform Board
the product description provide info on converting AC to DC so this seems to fit the bill.
anyone with experience in this field care to comment, provide some insight, etc.?

You could use a 5v power adapter (ex: iphone/ipod charger) with a usb cable and solder the + and - wires to the truer's motor. A 2s lipo pack makes the sanding drum and wheel spin very fast. Just make sure the watt output is high enough. Or you could just wire 6aa/aaa holders together to achieve 7.2v and use nimh batteries.

An iPod cable will not give enough amps. Most are .5 and iPads are 1 amp

the 2nd item has a rating of max 5a output. that combined with adjustable voltage is what looked promising. just want to make sure something like that is suitable. could be an easy job to put it in a box and call it a day. it already has the port for a standard power cord.

ok, traded the lcd adjustable unit with bill for the non lcd version which you can go down to about 11v. it's a bit bigger but adjust to a lower point which is what i'm looking for.
i also ordered the thing form ebay
Quote:
This kit provides a variable output power supply ranging from 1.5 to 40 V @ 5 A. It uses Low Dropout Positive Regulator LM1084-ADJ in TO220 package for delivering variable output voltage.
Input - 110-240 VAC
Output - variable output from 1.5 ~ 40 V @5 A Regulated low ripple DC voltage
Heatsink for regulator IC
On board bridge rectifier to convert AC to DC
Zener trimmed band gap reference, current limiting and thermal shutdown (provided by IC feature)
Power Battery Terminal (PBT) for easy input and output connection
Onboard PCB mounted Potentiometer (POT) for varying the output voltage
Filter capacitors for low ripple DC output
Four mounting holes of 3.2 mm each
PCB dimensions 63 mm x 112 mm
|
it should arrive in about 2 weeks and if it works as i hope it will, it will be much smaller and greater range of adjustability that will fit just about anywhere in my box and plugs right into any outlet.

12v supply and 0.5ohm resistor in series with the lathe motor. Has been working like a charm for over 6 months in our club lathe that is used on daily basis. Easier on the power supply and limits the power just perfectly so you can't heat up tires easily.
