Latest technology has given rise to highly functional electronics gadget with many advance features and facility. This has also made the electronics gadget expensive and sophisticated, requiring special care and support in order to function smoothly for a longer period of time. All this have created a space for standby power solution that provides safe and proper level of power supply to expensive electronics gadget. Sudden power failure can cause damage to the electronics gadget and in order to protect electronic equipment from damage standby power solution is quite helpful.

Standby power solution not only provides power to the equipment at the sudden break of the main power but it also prevents the electronic equipment from sudden surges or drops in power supply. Standby power supply is efficiently designed to provide continuous power to electronics gadget and it also monitors the power supply of the devices. Detecting problems with the main power supply, it automatically converts to battery power. The transfer of power from main to battery is done in such short time duration that it allows uninterrupted supply of power to the electronic devices. Standby power supply got its name from its function as it is not continuously providing power to the equipment, instead it start operating when main power supply goes out and the moment the main power restored it is back to its standby mode.

Standby power supply is the least expensive form of power protection system having line power as the primary source and battery as the secondary source of power. Standby power supply operates noiselessly and flawlessly transfers power supply during power failures. It can continuously provide power for 72 hours to the electronics devices but the actual backup time of standby power supply depend on the wattage consumed during the power failure.

Standby power solution in its simple form consists of a diesel generator, a manual changeover switch. In the case of mains failure the generator is manually started and by operating the changeover switch power can applied to the attached load. Complex form of standby power supply consists of both UPS and generator and is controlled by a fully automatic mains panel. In this form of standby power supply automatic panel sense the loss of power and automatically start the generator and connects to the load. Standby power solution not only supports the essential load but it supports the complete infrastructure so that the entire load operates smoothly.

Residential Backup Generators

Can you answer jcmc64’s question about Generators?:

I checked the battery and it reads around 5.5 Volts DC. SO I think the battery is good, it just won’t power off the protected outlets, just the unprotected ones. So there must be something wrong with the strip itself and not the battery

Wind Powered Generators

The DC Power Supply is a rather fundamental electronic device, however there are hundreds of DC Power Supply products on the market from dozen of manufacturers. Narrowing down the best product for your application and budget can be a daunting task. This article addresses DC Power Supply differentiators, functions and the applications they are best suited for. The article’s focus is DC Power Supplies used by engineers, manufacturers, quality professionals and electronic hobbyists for the purposes of R&D, manufacturing and testing.

Power Supplies can range in price from $50 to $20,000 and the cost is often directly proportional to the amount of power the device outputs. The primary function of a power supply is to regulate output voltage and current. It takes an input power and regulates the output power as to enforce a constant voltage and current. In the case of DC Power Supplies, the input power is converted from alternating current (AC) to direct current (DC). There are two basic types of regulated DC Power Supplies: Linear and Switching.

Linear power supplies can never output a higher voltage than the input source. In theory, a linear power supply that is driven by typical 110V wall outlet could only output 110V, assuming the device were 100% efficient. Realistically, no power supply is 100% efficient because power conversion always results in energy loss, usually in the form of heat dissipation. Therefore, linear power supplies usually output voltage that is significantly less than the input.

Switching power supplies can step-up, step-down or invert the input voltage. Switching power supplies are usually larger, noisier and more expensive than their linear counterparts, however, switching power supplies are typically more efficient.

Choosing the right DC power supply for your application requires definition of some basic design specifications: voltage range, current range, number of outputs, power cleanliness (known as “ripple”) and programmability. In general, the higher the output voltage and the lower the ripple, the more expensive the DC Power Supply. Multiple outputs and programmability features will also add to the cost.

The least expensive DC Power Supplies are ideal for electronics hobbyists and basic electro-mechanical applications where only raw power is required. It is likely that the devices being powered in these applications already have power-conditioning features that eliminate the need for precision input power. Low power, single output, DC power supplies range in price from $50 to $200.

Mid-range power supplies are best suited for non-critical, laboratory projects involving more advanced electro-mechanical applications or basic board-level testing. Mid-range power supplies might have multiple outputs, higher power ratings, lower ripple and precision, digital metering (+/- .001V, +/- .01A). Mid-range DC power supplies can be linear or switching and could range in price from $200 to $1,000.

High-end applications requiring high output voltage, advanced programmability (GPIB PC Interfaces), numerous outputs and very low ripple should budget in excess of $1,000 for their DC power supply. Many laboratory, R&D and testing applications could easily spend $5,000 to $10,000 per power supply.

This article has introduced some basic features and applications of DC Power Supplies. Before making your final purchase, be sure to consult the manufacturer and thoroughly understand all the specifications of a particular product. Choosing the best and most economical DC Power Supply for your application does not have to be a complex and time-consuming task. By identifying your design parameters, you will quickly narrow down product selection to a niche class of products from only a few manufacturers.

What are some good UPS BACKUP POWER SUPPLIES that is well worth its money? I need a strong power supply that will back up my 5 computers that is always running.

Standby Generator Reviews

From Chapter III of The Power of Yin:

Barbara: I would like to ask you, Jean, whether you have specific images of the future. Don’t use the word future if it is too linear.

Jean: I don’t even have to talk about my own images; I can talk about what is emerging. We don’t allow prophesy in our culture, so it goes underground and comes up as science fiction. In the 1880s and ’90s, the mode of science fiction was hardware science fiction: the ship to the moon, the ship under the sea, the laser. In the 1920s and ’30s, this becomes manifest. In the ’30s and ’40s, the cutting edge of science fiction is sociological science fiction: Brave New World, 1984.

And we’re well on our way to that. In the 1960s and ’70s, two dominant forms have been emerging: psychological science fiction and ecological science fiction. Consider Robert Heinlein’s Stranger in a Strange Land, or the books of Carlos Castaneda, or 2001. Wonderful science fiction! And they’re all about mutations or new ways of being.

Look at the characters of Castaneda - Don Juan - and Heinlein - Michael Valentine Smith from Stranger in a Strange Land. You find that they make use of different sense perceptions - synesthesias. They hear color; they see sound; they touch taste; they taste God; they smell time. They can look in the aroma of a desert flower and perceive galaxies billions of light years away. They have enormous freedom in time and space. They can experience five minutes as ten hours and thus review material that would normally take ten hours in five minutes. Their relationship to machines . . . all of these mythogems take place in modern times, but their relationship to machines is very different.

When Don Juan or Michael Valentine Smith are around, machines go haywire, break up, disappear. It’s as if they’re making use of a different symbiotic ecology to get things done.



I know, from the point of view of what I know about the instrumentation and the fraction that we’re using, that a lot of these so-called third-world modes of doing things - be it medicine, be it transportation, be it modes of communication - are resonant in us. But we are so tuned to ourselves as prosthetic extensions that we have lost this enormous amount of knowledge. Anything that you read in Castaneda or in Heinlein we can demonstrate for you in the laboratory. Including having Ford cars appearing and disappearing in the living room, as occurs in Castaneda. That’s a very simple thing to do.



Time: we could give you five minutes of clock time to experience hours and hours in which to rehearse your piano, or golf. Because of the very minute synaptical connections that would have been made in a trance state, with intensive imagery of rehearsal, and subjective time distortion, you would come out at the end of five minutes as if you had had ten hours of practice, and you would be that much better. This is something that musicians have always known. We can do this in the laboratory. The brain can process millions of images in microseconds: images have a different time. It’s like falling from a cliff, expecting to die, and in that very brief time reexperiencing your entire life - in its own time.



And another thing is that the remembering of the future may already be coded into the potential of ourselves.
