Product Description
There are some features of the Computer Power Supply which should be consider when buying or replacing your old Power Supply. Here is a power supply features to be considered:
  • The mean time between failure (MTBF) or mean time to first failure (parameter MTBF (Mean Time Between Failures) or MTTF (Mean Time To Failure)). It’s estimated the average time interval in hours, during which the expected that the power supply will operate correctly. MTBF power supplies (such as 100 thousand hours or more) usually is not determined by empirical tests, and otherwise. In fact, manufacturers have used the previously developed standards to calculate the probability of failure of individual components of the power supply. In calculating the MTBF for the power supplies are often used data on the load power supply and ambient temperature, which carried out the tests.
  • The range of input voltage (or the operating range) , which can operate the power supply. For the voltage range 110 V input voltage values are typically between 90 and 135, for input voltage of 220 V – 180 to 270 V.
  • Peak inrush current . This is the highest value of current provided by power supply at the time of its incorporation, expressed in amperes (A). The smaller the current, the less thermal shock tests the system.
  • Time (in milliseconds) to keep the output voltage within a precisely defined voltage ranges after disconnecting the input voltage . Typically, 15-25 ms for the modern power supplies.
  • Transient response . The amount of time (in microseconds), which requires a power supply to set output voltage in the well-defined range after a sharp change in current output. In other words, the amount of time required to stabilize the output voltage after switching on or off the system. Power supplies are designed for uniform (to a certain extent) the current consumption of the devices on your computer. When the device does not power consumption (for example, the drive stops the rotation of the disk), power supply may apply too high output voltage for a short time. This is called the ejection, the transient response – this time, which expends power supply to ensure that the voltage had returned to accurately set the level. In recent years, achieved considerable success in solving problems associated with the phenomena of emission sources of supply.
