Product Description

    • It's often the case to sue the electronic machine parts when transforming the electrical system into the machinery system of a device.
      ln this case, the inductance of the coil creates the pulse counter voltage of high energy.
      Let's suppose the case in which the contact point  of circuit switches on and off.
      lf there's voltage involved in the contact point, there is current when the contact point is closed.
      When it's open, the counter electromotive force of inductance creates voltage along with sparks, glows and ARC.
      ln addition, the vibration of high frequency will potentially interfere with the electronic circuit.
      Due to the sparks, the contact points get to be exhausted.
      transformed or desposited, the increased oxidative contact resistance on the surface and contact defects will reduce the life.
      The circuit inserted between the contact points in order to prevent sparks is called the spark quench circuit, and it's parts are called SPARK KILLER(SPARK QUENCHER).

    • Characteristics

      1. lt has a great durability of overload.

      2. The effects of chattering and contact point vlbration on the surge voltage are huge.

      3. It's effects on exterior surge vltage are great.

      4. Since it's impedavce against the high counter frequency is very small, it can control the high frequency noise of low levels.

      5. lt protects SCR and SSR and lmproves dv/dt, contributing to having the CR time constant.

    • Use

      - Various electric circults for opening and closing

      - Machine tools

      - Automatic machines

    • Precautions for use

      When high frequency power is input to the spark killer(Spark quencher) Due to the high heat from the resistor by conduction phenomenon of the capacitor in the CR circuit Temperature increase of the spark killer(Spark quencher) in use, so a spark can occur or more or less so that the killer 5℃ We should use and inspection is essential.
