High voltage DSS

Features

  • Small size and high DC spark-over voltage (2700V, 3000V).
  • The DSS-272M passes 1200VAC - 3s and 1000VAC - 1min test; the DSS-302M passes 1500VAC - 1min withstanding voltage test.
  • Quick response to surges, low limiting voltage.
  • Small capacitance and excellent insulation resistance ≥ 100MΩ
  • Stable for repeated discharge tests and for wide environmental fluctuations.
  • No polarity.
  • No dark effect.
  • UL1449, CSA, and TÜV recognized.
