  • Advantages of Semiconductor Laser Diodes Versus Helium Neon Gas Lasers
    Although HeNe gas lasers offer exceptional reliability and optical quality, users are quickly replacing them in their OEM applications with semiconductor laser diode technology. Laser diode modules offer many physical and electronic advantages over HeNe lasers. HeNe gas lasers provide superior

  • Technical Article: Electronic Tap Switching Voltage Regulator
    The typical electronic tap switching voltage regulator works very much like the mechanical tap switching regulator - except that it replaces mechanical servo drives and brushes with solid-state semiconductor switches. Rather than using a motor to move brushes connected to the regulator output
  • Technical Article: Electronic Voltage Regulator Characteristics
    Electronic voltage regulators are typically designed for indoor, low voltage applications and are air-cooled (i.e. using dry-type transformers instead of oil-filled). Other characteristics of tap switching and double conversion EVRs differ substantially so they are listed separately below
  • Technical Article: Double Conversion Electronic Voltage Regulator Operation
    capability and higher cost than a true double conversion or tap switching electronic voltage regulator. Like the full power semiconductor EVR, double conversion electronic voltage regulators have a very low tolerance to high load currents above the normal rating of the unit. Double conversion EVRs
