High voltage DSS

Features

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