  • How to disassemble an integrated power supply

    How to disassemble an integrated power supply

    In this video, we dive deep into the guts of a standard ATX power supply unit (PSU), showing you exactly how to disassemble it safely and effectively. As it contains many electronic components that might be useful for your Electronics hobby, it can be worhwhile to dismantle it. Desolder whatever components can. How do i disassemble this PSU without frying myself? I really want the switch since it's perfect for a side project and I got this old pc for free! However I don't know how to really discharge the capacitors safely. This submission has been allowed provisionally under an expanded focus of this sub. The task of a PC power supply is to convert the power from the wall (120 or 240 volts AC) into stable power at the DC voltages that the computer requires. To achieve these goals, power supplies use a. Ken Shirriff performs another thorough teardown and reverse engineering, this time on a computer power supply. It's not possible to pry it open without heavily damaging it.

  • What are the reasons why stripping pigtail fibers can easily cause scratches

    What are the reasons why stripping pigtail fibers can easily cause scratches

    Contaminated connector end-faces (dust, oil, or scratches). Improper splicing techniques (e. Excessive bend radius violations (>10mm for standard SMF)., UPC. One begins with making a tiny scratch on the side of the fiber, e. with a sharp diamond, carbide or ceramic blade, before or while some defined tension or bending is applied to the fiber. This causes the fiber to break, starting at the mentioned fracture point. Those are problems anyone can identify with visual inspection and learn from the inspection how to do it correctly in the future. Consequently, these imperfections can lead to significant signal loss (attenuation), back reflections, and catastrophic failure. What happens if you damage the fiber during this production step? A tiny scratch or nick in the optical fiber is like a time bomb.

  • Do power lines affect fiber optic cables How should they be connected

    Do power lines affect fiber optic cables How should they be connected

    There are no interference problems with fiber optic cables and power cables. Fiber uses light for data transmission. OPAC cables can be installed on existing ground wires or phase conductors, even OPGW or OPCC to expand communications capacity. Special devices are required to prevent coronal discharge near towers and at drops for splicing because the high-electric fields around high-voltage. One way round this is to install aerial fiber cables close to power lines, such as on mixed use poles which also carry electricity. Obviously, these fiber cables need to be resistant to electricity, which can be difficult as many aerial cables contain high tensile steel (HTS) for tensile strength. ntly, there are a limited number of industry documents that address the requirements for optical fiber cables near high voltage circuits. This strength member can be made of steel or insulating material.

  • What dB is considered normal for a light power meter

    What dB is considered normal for a light power meter

    The normal value of an optical power meter is 12dbm. An optical power meter is an instrument used to measure the absolute optical power or the relative loss of optical power passing through a section of optical fiber. ” Loss is a negative number (like –3. The dBm scale is logarithmic, meaning a small numerical change represents a large change in actual light power. Above 0 dBm is considered "high power", and specially adapted units may measure up to nearly + 30 dBm ( 1 Watt). Engineers use the decibel-milliwatt (dBm) to quantify the absolute.
