  • Special Thermistors Limit Inrush Current
    High inrush current can be produced when equipment is turned on. If steps are not taken to minimize this inrush current, it can damage power devices and reduce equipment life. A safe and cost effective way to reduce inrush current is to use an inrush current limiter (Surge Limiter), which
  • Mechanical torque limiters still make sense
    overload protection. Electrical overload protection has been used since the days of the first industrial electric motors. Back then it simply protected motors against thermal overloads. Today, however, protection devices monitor many parameters - such as current, voltage, force, torque, rotation
  • Why Use Mechanical Torque Limiters in a Servo Drive System?
    Electronic current limiting is not always a 100% effective way to prevent torque overloads in a mechanical system
  • Power supplies for the next generation of CompactPCI systems
    out voltage fluctuations and interference. Also important for the. system is an output current limiter for safety purposes. This prevents, for example, a. damagingly high current flow in the event of a short circuit on a board. Other technical. requirements for PSUs are overvoltage protection
  • Green Technology: How to power an energy-efficient light
    the tube gas by applying a high voltage to heat the filaments. The ballast also serves as a current limiter when the lamp is on. The problem with old-style ballasts was one of both bulk and inefficiency. CFLs only took off with the advent of electronic-ballast circuits that were both economical
  • Designs on the Winner's Circle
    the limit. "The IRL limiter is called a hard limiter because when it activates, it shuts down the entire ignition system, " says GM Racing engineer Ned Baker. "It's like an on-off switch. When the limiter is activated, engine output drops to zero. The limiter doesn't restore current to the ignition
  • Design and Development of Medical Electronic Instrumentation
    to perform volume-conductor experiments with a voltage-to-current converter. and physical models of the body. In Chapter 7 we look at the principles and clinical applications of electrical stimulation. of excitable tissues. Projects include the design of stimulation circuits for implantable. pulse
  • MICRO: The Hot Button
    . Although it appears the damascene tandem will continue to push down the scaling roadmap for awhile, alternative interconnect options will be needed in the not-too-distant future. This issue 's Hot Button participants weigh in on the background, current and near-term outlook, and longer-term challenges
