Power Supply Woes

i blew everyting off, including the power supply. I tried a varistor, but it was too strong I think because it was letting 120v go through but I don't think it was letting enough current through cause it wouldn't Just not sure if it is safe or not to not have that component there and be replaced by a short.

The switching power supply inherently has more harmonics because the waveform is not purely sinusoidal. You don't have a UPS, do you?

  1. Amateur radio operators are scattered all over the world and if you happen to see a home with a lot of antennas or towers, you may be in luck.
  2. If you know of a friend or neighbor that is an amateur radio operator, he will most likely be able to help you out and may not even charge you for
  3. Also my power supply is very small and lightweight.

If installed reversed, the capacitors will actually explode and leave a real mess around the board. It's just that some have hash and noise issues.

QUESTION?

yes I have what they consider a small transformer box coming for the pump to be housed in and we are looking into a shielded cable for the 6 foot run In both types of supplies there are filter capacitors.

Two connectors provide the power to the main board and the display board. I also paid a lot less when they had a sale on, so it's often worth shopping around. See what happens. I got mine from here: http://www.nevadaradio.co.uk/amateur.../nevada-psw-50 where there is a little more information regarding this particular order supply.

Have you checked all connections inside the PC (drives, motherboard, PS, etc)? this contact form Wattmeters, amplifier, too.Check your coax (including jumpers) too. They come in various sizes and most of them are covered with a thin plastic layer either black, dark or light blue with leads coming out of either one end or Again, electronics like power applied slowly. (The naive will say that low voltage is destructive.) We add an inrush current limiter to extend /increase electronics life expectancy.

It means that your ESQ1 is most likely over 15 years old and you are operating on borrowed time. The higher input voltage overcomes the power supplies ability to regulate. before i blew it out, it worked well.

There are three voltage regulators, 7805 for the 5 volt supply, 7812 for the +12 volt supply, ans 7912 for the -12 volt supply.

These capacitors are like small storage devices like batteries that remove any voltage ripple components from the mains AC or the switching frequency. They are usually only about 50% efficient. They are a little pricier than the Astron ($155 vs $130), but well worth it in my opinion. 73, Ray, K9DUR Like Comment 0 people like this 2016-02-04T15:25:11+00:00 David Warnberg 429 Don't take anything for granted.tada -----Willy Flag Permalink This was helpful (0) Collapse - Not Necessarily The PS by sunwatcher / July 14, 2008 12:43 PM PDT In reply to: yeah

Brian Cooley found it for you at CES 2017 in Las Vegas and the North American International Auto Show in Detroit. It is the one part of any piece of equipment that has to work the hardest. Use the ATX one I just bought a new corsair one with all the latest connectors and grounding the green wire worked on it just fine. Check This Out This means that if your equipment requires 45 watts of power, there is about 45 watts of heat given off.

So far, it's rural enough that my noise floor is -125 dBm. The psu works fine, shorted out there, but I am wary that that might blow something else up if it runs like that. These voltage regulators are physically bolted to the rear fin heatsink.

The extent of the behavior will be determined by the designers ability to "over design" the power supply to accommodate the continuously degrading values. I had a catalog of a military surplus store in Lima, Ohio that sold used electronic equipment (this was before the internet) & the name of the company is Fair Radio
