    . standby supply. Electrical Equipment Handbook by Philip Kiameh Discusses: magnet pilot exciter. standby supply. earthing resistor. Electrical Power Systems Quality by Roger C. Dugan Discusses: triplen harmonic currents. static switch. exciter field. The Motorboat Electrical and Electronics Manual
  • Using Power Resistors as Heaters
    . They are especially useful in situations where the heat must be isolated or concentrated in a small area. For example, Riedon power resistors are used to eliminate condensation on outdoor security camera installations. Heat from the resistor keeps the lens temperature above the dew point
  • Using Power Resistors as Heaters
    the resistor keeps the lens temperature above the dew point. With small "footprint" resistors, heat is localized to optimize energy-efficiency of the system. Another application uses our resistors to warm and control the temperature of samples in blood analyzer systems. In electronic circuits, power
  • Introduction to Current Source Power Units
    ) is used in our battery operated power units to keep power drain to a minimum to prolong battery life. In our line-operated power units, we utilize a clamped base bi-polar transistor constant current circuit. (see Figure 2b) The value of emitter resistor Re sets the value of constant current. Dytran
  • Computer Power User Article - Probe Your PC
    A thermistor is basically a type of resistor in which its resistance changes depending on temperature. The change in resistance is what makes a thermistor useful as a temperature sensor. When English author and philosopher Sir Francis Bacon proclaimed knowledge is power some 400 years ago, we re
  • D/A Conversion Using PWM and R-2R Ladders to Generate Sine and DTMF Waveforms
    of complex analog waveforms.: (PWM and R-2R Ladder). Both the Pulse Width Modulation (PWM) and resistor ladders require only a few external components to create a D/A converter with the PICmicro? microcontroller series. These techniques can be used to generate dual-tone multiplexed frequencies (DTMF
  • Thermistors in Single Supply Temperature Sensing Circuits
    " originated from the descriptor. own power, the device operates in the voltage-versus-. THERMally Sensitive ResISTOR. The two basic types. current mode. In this mode, the thermistor is best suited. of thermistors are the Negative Temperature Coeffi-. to sense changes in the ambient conditions
  • If you can't conserve energy, stay out of the kitchen
    processor (MCE) dedicated to managing the PM synchronous motor. The chip implements a sensorless control algorithm that eliminates the need for feedback from Hall-effect sensors to manage commutation. A single shunt resistor is used for motor phase-current. If you can't conserve energy, stay out
