Choose the Right Electronic Load

Written on August 20, 2015 at 7:20 am, by

Electronic loads have many different applications, including testing power converters and modulating a current supply while performing other tests. They are easy-to-use and provide much higher throughput than resistors when varying loads are needed. When choosing an electronic load, the most important specifications that you need to consider are the voltage rating, current rating, and […]

EN61000-3-2 Sets the Standard for Harmonic Currents

Written on August 4, 2015 at 11:22 am, by

While switch-mode power supplies have many advantages, one of their disadvantages is that they are a non-linear load, and because of that can inject harmonic currents into the electrical distribution system. Devices with switching supplies include domestic appliances (TVs, microwave ovens, lighting equipment and dimmers), and office equipment (PCs, printers). Motor-driven equipment can also cause […]
