How do you reduce 100Vdc to multiple outputs of 12vdc 24vdc and 48vdc?
I wish I had the perfect answer for you because it's actually a very interesting question. Typical responses might include using DC regulators that cannot handle your input voltage, or perhaps Zenier diodes to clamp the voltage down. Neither is a good solution. What you're trying to achieve has been done for many years in VCR's, TV's, and many new digital appliances. They are faced with a somewhat similar dilemma to you in that they have 120 volts AC (here in the US) and they need to reduce it down to some common levels such as +12 volts, -12 volts, and/or +5 volts. Here's how they do it: First, they recognize the uselessness (due to inefficiency and heat generated of just using a step-down transformer) by converting the 120 volts AC to DC (believe it or not) with a bridge rectifier. It is also filtered a bit with capacitors and perhaps even clamped a bit with a Zener diode. The new 120 volts DC is then fed to an oscillator circuit which drives a high-powered switching device (a transistor for example) into their own custom-made transformer. The output taps for the transformer are wound proportionally to achieve the desired voltage. Next, each output is rectified (because it's AC) to DC, filtered with a capacitor, perhaps regulated (with a regulator like an LM7812 for 12 volts). The now have their desired output voltages. Constructing such DC-to-DC converter would be pretty much impossible unless you plan on hiring an engineer to design it and expect to make millions selling it. Yea, I know this doesn't answer your question, but that is how it's done in the "real" world. Note that you can't use an LM317 voltage regulator because your input voltage exceeds the maximum of the device. Perhaps someone else will know of a regulator than can handle 100 volts, but I don't know of one. I would search the 'net for DC to DC inverters and see what you find. I haven't done any searching myself, so you may find nothing. As an interesting aside, why 48vdc? Are you building your own Telco switch? ;-) <><><> In many circuits, a voltage-dropping resistor or resistors are used for this function. This will work if the need is for a bias or voltage level (and not to supply power). You need to know the current to calculate the proper resistor value from Ohm's law, and also make sure the resistor can dissipate the power (heat) that may be generated.
What is the difference between microfilm and microfiche?
Both are used to store documents as photographic visual images. The images may be produced either via photography or by a special printer connected to a computer. Both need a viewer to display and magnify the images. The difference is in the physical layout of the images. With microfilm all the images are recorded in a single straight line one after the other along the film strip. The strip is very long (sorry don't know how long) wound on a spool and is typically (I believe) 35mm wide. With microfiche the material is made into separate sheets round about 6 inches wide by about 4 inches high. The images appear in columns on each fiche, typically 10 images in each column and 12 rows of columns, though this may depend on the application. Provided there is an index to the fiche so that you know one to look on it is quicker to locate required images on fiche than on film. Without an index it is hopeless. I once worked (for about 4 years) in an office with the filling on fiche, the fiche were in boxes each holding 2000, the boxes were in racks 10 high and there were around 30 racks. I earlier worked for Kodak in the research laboratory where the special fiche film was being developed.
What is the full form of IRG?
Tape storage is primarily used for archival storage. The recording medium is a thin polyester tape between 0.38cm and 2.54cm wide, about .025mm thick and coated with magnetic particles. The tape is wound on wheels of various sizes. Data is recorded sequentially, one byte after the other, from the beginning of the tape to its end. Access times for tape storage are much slower than for floppy diskettes or hard disks.The following diagram shows how data is stored on the disk. The read/write head is comprised of several tracks, 9 tracks being very common. This means nine bits are recorded across the width of the tape simultaneously. Using nine tracks, one byte of data plus a parity bit is recorded at a time (vertically). Characters are grouped together to form a record (often called a block). Each record is separated from the next record by a blank inter-record gap (IBG). Each record is preceded by a header field. The IBG allows the software to position the tape for recording or playing at specific record numbers. Physical markers are used to indicate the ends of the tape, and may be metallic foil, clear plastic or software markers encoded on the tape. Software encoding uses BOT(beginning of tape) and EOT (end of tape) indicators. IRG=IBG
What are the three things that are considered components of wound repair?
ligation, exploration, and debridement
What three criteria determine wound repair?
1. Length of the wound in centimeters 2.Complexity of the repair 3. Site of the wound repair
Why do you stop bleeding when you get a cut?
There are platelets in the blood that helps to plug and stop the blood flow. Compressing the wound for a few minutes will also help. keeping the wound clean and covered with a band aid will help to prevent an infection. Blood components are: red blood cells, white blood cells, and platelets.
What type of cells in humans are needed for constant repair in humans?
All of them. White blood cells attack disease and the red carry blood and oxygen to the wound. Red blood cells also repair the body.
Why would an open wound would need a bed of granulation for wound healing to occur?
Granulation tissue is tissue with good blood circulation and adequate blood supply is needed for a wound to heal.
What would normal vital signs be for a victim of chest gunshot wound?
If they are normal, they would be the same as if the wound was not there at all. But there is nothing that would be normal with gunshot wound. It would depend on where the wound is and how much blood is lost.
Why is imflammation helpful on a wound?
Inflammation and heat radiating from a wound site indicates an increased blood flow to the wound itself, this means extra nutrients, protein's, antibodies and other vital components for healing are reaching the wound enabling it to heal properly.
Why is pus good around cuts?
Because the white blood cells that have gone to repair the wound, have died. Resulting in pus.
How long does it normally take an open wound about 2cm deep and 2cm wide to heal?
If it's a simple wound, it would take about two weeks. It infection is involved, or if nerves and blood vessels require repair, it could take quite a bit longer.
What is the process your hand would go through repair the wound of a paper cut?
mitosis
Why can not apply methol to a bleeding wound?
It is a blood thinner and would prevent the blood from clotting, which would increase the bleeding.
Why would your partner smell blood and you are not having your menses?
may be they have a wound.
