Switching power supply from china are no good the caps are under rated for Temperature and power factor and voltage.

Add to watch list Remove from watch list. Please enter a number less than or equal to 8. The ‘extra’ electronics is for regulation. No additional import charges at delivery!

The 2SD is the series regulator transistor. Select a valid country. D That there’s funny! Linear meaning that everything happens at line frequency, 60 hertz. This is the 2sd977 you want to return the control to when you are done applying contact cleaner and working the control back and forth a bit.

United States and many other countries See details. Other offers may also be available.


Thanks for all the education!: Skip to main content. That is why a switching type power supply, like in computers, have much smaller transformers and capacitors as they first simply rectify the line voltage to get high voltage DC then 2sf797 that at a much higher frequency, 40, tohertz, so that the transformers need much less iron to perform properly.


Hi all I have work in electronics for over 40 years, in aerospace for 9 years. Thanks Robin, even I could understand that explanation. This item will be shipped through the Global Shipping Program and includes international tracking.

A cheap analog meter is probably best for this test. Have one to sell? 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.

A simple calculation is needed for such a resistor. Also, that power supply has remote sensing regulation. So a single 36 Ohm, 8 or 10 Watt resistor will allow you to operate that coil.

Read more about dattasheet condition. As long as it’s somebody else’s toes that is.

A 5 Watt resistor would work but I would step up to 8 or 10 Watts for 2sd779 little headroom which would give longer life. Please enter 5 or 9 numbers for the ZIP Code. Operating Junction Temperature Tj: This is a little more than the cliff notes version but I hope it helps. Since 24V at 2.

Please reduce my ignance and educate me; the Cliff Notes version.: The regulator ic in there, theis a decent regulator. OK, nudder edumacation wanted just sayin’. 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 Without regulation the voltage will not be stable with varying load currents.


That will be your voltage adjust.

Looks like I got my money’s worth; that’s a pretty decent piece of equipment. Very simple to do and you end up with one supply source for all the control, and if they do not require regulation then simple bridge and caps are all that are needed.

You datashdet put that resistor in series with the coil: Sell now – Have one to sell? Perhaps a small CNC device with some of the little stepper motors I’ve got ratted away around here somewhere Image not available Photos not available for this variation.
