TLO-3-2 (ТЛО-3-2) neon luminophore tube is used as indicator, signal element in various electrical and electronic devices. The glow is ORANGE color. Tube can be used in AC and DC circuits, and they should be included in series with the ballast resistor, wherein the operating current is no more than 3mA.

Main technical characteristics:

  • Glow color: ORANGE;
  • Brightness: 50 candel/m2;
  • Type of current: AC/DC;
  • Maximum discharge current, mA: 3;
  • Discharge voltage, V: 185;
  • Working voltage, V: 220 and 380;
  • AC/DC ballast resistor is equal for 220V is 47 kOm; for 380V is 100 kOm.
  • Lifetime, hours: 5000;
  • Diameter: 15.6 mm;
  • Length: 41.5 mm;
  • Socket type: B 15s/18.

    The value of the ballast resistance at a different supply voltage can be calculated by the formula: R = (U1 - U2) / I, where:

    R - ballast resistance;
    U1 - power supply voltage;
    U2 - maintaining voltage;
    I - operating current.
