  • Soldering Jewellery

    Soldering can have many applications, one of them being jewellery making.

    Jewellery making is up there as one of the biggest businesses in arts and crafts, and soldering gives you the freedom to create unique pieces, as well as practise your technique.

    Methods

    There are two different methods to soldering jewellery: Continue reading

  • Difference Between Digital & Analogue Oscilloscopes

    An oscilloscope is a laboratory instrument commonly used to display and analyse the waveform of electronic signals. In effect, the device draws a graph of the instantaneous signal voltage as a function of time. The two basic types of oscilloscope are digital and analogue. Continue reading

  • Power Supplies - the difference between switch mode and linear.

    There are considerable differences between linear and switch mode power supplies.

    We stock both designs in our bench power supply range. Here is a handy table to provide you with an overview of the main differences:

     

    Linear

    Switching / Switch mode

     Strengths Low noise and EMC disturbances

    Good line and load regulation

    Fast transient response

    Can produce very low current output

    High efficiency (75% average with some around 95%)

    More affordable for higher power

    Lighter weight

    Can't supply low voltages and

    needs to supply a minimum current

     

     

    Weaknesses

     

    Low efficiency (30-40% average)

    Weight (transformer)

    Larger heat sinks

    More expensive for higher power

     

     

    More noise (including impulse noise and EMC disturbances)

    Much slower transient response compared with linear
