Introducing TNC-PQR will bring the
following changes

01Prevention of disasters, and abnormal voltage and poor communication of platform safety facilities (safety door, etc.)

  • Prevention of electric shock disaster due to electrical impact

  • Prevention of electrical shock and fire of electronic wheelchair

  • Protection of abnormal voltage of platform facilities (safety door, etc.)

  • Satisfying international standards for equipotential and touch voltage of platform safety facilities

02Prevention of disasters, and abnormal voltage and poor communication of platform safety facilities (safety door, etc.)

  1. Complete prevention of electrical shock,
    electrocution, Arc fire hazard

  2. Stability of control system (PSD, safety footboard, etc.)

  3. Allowed voltage according to KEC
    EN technical standards: 60V
    (PQR allowed voltage: 2V or lower)

  4. Alleviation of potential difference between rail potential and platform facility

  5. Real-time remote monitoring(optional)
    (provided upon operator’s request)

  6. Free periodic inspection service (Warranty condition)
