Toroid find of the month!

[CJ900RR]

One of the biggest cost in a GC is the toroid. I have been waiting to buy a good one because i just wasnt able to spend that money right now.

But today, at work, we where going to send away a machine to the junkyard for recycling. I asked if i could take a look inside and my boss said, yeah just take what you need. I open it and what do i found?! A big toroid smileing right at me

I take out the PSU in the machine, hook it up and measures 1 x 15V, 2 x 25V and 2 x 27,5V! So perfect. I dont know how many VA it is but judgeing by size i would say its enough. It ways in at 10,5 kg (23.14 pounds?)

The psu also contained 7 ROE elyts at 22 000 uF/40V, and 3 heatsinks measuring about 25 x 40 centimeters (10 x 16 inch?), and a lot of resistors, caps and other stuff.

Guess who is lucky right now

Note, the United portable cd-player is in the pick as a size reference...

nice find! one of those secondary pairs might have a lot more current avaliable than the other. i am not sure how to tell unless one has fatter wires.

You know what else is good. Having a father that works for telus. Working in the server rooms / psu rooms where they have all the power supplies and generators and banks of batteries that run 2v @ about 5000amps per battery is pretty sweet. Pops has brought lots of heat sinks and caps and other stuff my favorite being heat sink's and Teflon wire. :P

I know that the machine need + and -35V so i think that the current is the same at both pairs. And all pairs including the 15V is equaly fat.

You should see the booster from where i got the 3 heatsinks, a PCB 2 foot wide and allmost 1 foot high full of stabs for power handling. Some Motorola MU14002, MU14003, something marked "J55 made in Japan" (no idea of brand) and some marked ST175 i think. All in TO-3 package. Dont know if they are good for anyone but if you need them let me know. Plus a lot of resistors 0,01% 5W and other good stuff.

You are one lucky guy! Scrapheap challenge

I'm just curious. Which was the function of such a machine?

[CJ900RR]

Hi Eva.

The machine where used for assembly surface mounted components on pcb's. Thats what i do at work. It's called MYData TP9 II and is only 10 years old, but allready to slow for production. It had a capacity of 4000 components/hour, but my new one, MYData MY15, can place 20 000/hour. You can read more att http://www.mydata.com
