Designed for high speed, high current, high power applications. The case of that regulator is probably not. This means that the 12 Volts you get at the coil is not regulated and you can not add additional devices at that 12 Volt point without changing the 12 Volts to another value.

Milton, The transformer is typical of that in a linear power supply. Refer to eBay Return policy for more details. Perhaps a small CNC device with some of the little stepper motors I’ve got ratted away around here somewhere Skip to main content.

This is the point you want to return the control to when you are done applying contact cleaner and working the control back and forth a bit.

Thanks for all the education!: Get the item you ordered or get your money back. D That there’s funny!

High DC current gain: Please enter a number less than or equal to 8. The regulator ic in there, theis a decent regulator. Hi all I have work in electronics for over 40 years, in aerospace for 9 years.


The two big precision power resistors off to the left are for that. I would not go to the bother of using regulators off of that supply. If you carefully mark the position it’s in, then rotate it a bit power off and stored charges dissipated, or unplugged for the night you will feel a point where the contact has made a tiny dent in the track.

They tend to develop an intermittent, which will throw things out of kilter- enough at times to cause damage in the supply, not to mention whatever load is attached.

Switching power supply from china are no good the caps are under rated for Temperature and power factor and voltage. Dwtasheet to watch list Remove from watch list. Be the first to write a review. Delivery time is estimated using our proprietary method which is based on the buyer’s proximity to the item location, the shipping service selected, the seller’s shipping history, and other factors.

VR2 is marked V. See other items More A simple dropping resistor will drop the extra 12 Volts and would be more reliable. I have little electronics knowledge but after datasbeet the weight of the thing, looking at size of the components and the hand soldering, I totally agree with you.


I think Max is right.

A 5 Watt resistor would work but I would step up to 8 or 10 Watts for a little headroom which would give longer life. Only downside is the engineers’ “rule of toe” – you can work out how many Amps it’ll deliver by dropping it on your foot, count the broken toes, that’s how many Amps Read more about the condition.

From what I have seen is that a linear power supply last minnie times longer then switching power supply and take power surges better.

If you want to get fancy and make nice neat PCB’s, there are some 2wd797 video tutorials on the “Eagle” PCB software – there’s a freeware version you can download that’ll do small PCB’s from circuit diagram to finished 2sx797 and even CAM files An error occurred, please try again.

Careful how you mount this thing.
