UPS Selecting >>>>>
Help and Tips for Cost Effective Uninterruptible Power System

            First, use our guide How to Specify a Cost Effective UPS system, in order to decide  UPS 
            Type, Size, and required Backup Time. Next, consider the following helpful tips before 
             concluding your Power UPS buying deal.     
  • Connect to the UPS only critical loads which need to be protected. Certain malfunctions in consumers connected to the UPS may cause total output shutdown.


  • Increase UPS capacity to allow for future load capacity expansion.


  • Take in account that rated battery backup time refers generally to new batteries and deteriorates during battery's life time.


  • Consider selecting the next UPS size to increase Backup time. Rated Battery backup time refers generally to full load, increasing  almost threefold at half load.


  • Consider air conditioned location. Battery lifetime is strongly temperature dependant.
            Battery Life decreases by 50 percent with every 10 degrees in temperature rise.  
  • Don't buy backup time that you don't need. Longer autonomy time does not mean  better equipment.


  • When considering Online UPS, prefer systems with extended battery option and with   ability to increase power by adding parallel units when more power is needed.


  • Unless you use a Distribution Board at the output of the UPS, make sure that the UPS is equipped with the required types and amount of output receptacles.


  • If you do not see a clear advantage for your application, don't pay more. Higher price does not necessary  mean a better or more reliable unit.


  • Don't buy any extras if you are not sure that they  are needed for your application. Most can be added in the future whenever required.


  • Some manufacturers provide 6-figure guarantee to cover damage to  your equipment the enormous sums are seldom meaningful, you won’t generally  be paid above the value of your backed up hardware. The main items, such as loss of data, or  discontinuity of service to your clients are not always covered.


  • Make sure that the UPS comes with software which shuts down gracefully and  automatically all backed up computers.


  • Make sure that the UPS includes surge protectors on input and communication lines.


  • Make sure that the UPS  performs automatic battery tests, warning whenever the batteries should be replaced. Otherwise you will discover that your computer goes down when the  lights turn off.  Don't be tempted to buy manually initiated test. Nobody remembers to keep the routine.


  • Avoid falling into a trap of misleading terms. Smart UPS should regulate output Semi-sinusoidal output is not sinusoidal. On -Line must be  Double Conversion and able to regulate output frequency. Note that  "Automatic self-test " does not always mean battery test as well.


  • Prefer hot swap-able Batteries. The batteries of some systems are not accessible by
      the operator and should be replaced by a qualified technician.
  • When purchasing the UPS, make sure that after sales service is in good hands. Check
      who provides the service, how fast it is, and whether it is provided in your premises.
  • Check  Guarantee Duration, Where and When it is provided. It is not uncommon to get several  years guarantee, 7 days per week at your premises.


  • Check the make of the UPS you are going to buy. Check that manufacturing company is at least ten years in the UPS business. Get recommendation if the company is unknown, or check listing in our  UPS Manufacturer's directory.


  • Some UPS systems may not function properly with specific loads. Unless you have professional consultation  we strongly advise to make sure with the UPS  
     supplier that offered equipment works properly with your specific consumers.
     And that you are covered against any malfunctions due to possible inadequacy
     of the offered UPS with your critical hardware.

What Is Ultrasound

What Is Ultrasound An  ultrasound scan , also referred to as a sonogram ,  diagnostic sonography , and ultrasonography , is a device that uses high frequency sound waves to create an image of some part of the inside of the body, such as the stomach, liver, heart, tendons, muscles, joints and blood vessels. Experts say that as sound waves, rather than radiation are used, ultrasound scans are safe. Obstetric sonography is frequently used to check the baby in the womb. Ultrasound scans are used to detect problems in the liver, heart, kidney or the abdomen. They may also be useful in helping the surgeon when carrying out some types of biopsies. The word "ultrasound", in physics, refers to all sound with a frequency humans cannot hear. In diagnostic sonography, the ultrasound is usually between 2 and 18 MHz. Higher frequencies provide better quality images, but are more readily absorbed by the skin and other tissue, so they cannot penetrate as deeply as lower fre

Electronics Ciruits : Mosquito repellent circuit

Image
Electronic mosquito repellent schematic circuit This  electronic mosquito repellent schematic circuit  diagram based on the  555 timer IC  is a simple and useful  mosquito repellent circuit  . This mosquito repeller circuit generate an ultrasonic sound with a high output frequency that  allows spreading mosquitoes within a wide radius . The circuit is quite simple and require few external components . The oscillation frequency is given by the value of the R1, R2 and C1 components and can be modified changing the value of components or replacing the R2 fixed resistor with a variable resistor ( potentiometer ) . The actual oscillation frequency of this electronic mosquito repeller circuit is around 45 KHz ( 46.5 KHz) so you need to use a good high frequency speaker , you can use a piezo speaker . The circuit can be supplied from a 9 V DC power supply  . This repeller circuit can be used for almost any animal , it works on  : cats , dogs , rats  . Even if you don’t hear the sound ge
