High voltage DSS Series
The high voltage DSS Series for communication lines has excellent AC withstand voltage, and some products are certified by UL1449, CSA, and TUV.
Useful informationFeatures
- High DC spark-over voltage in spite of compact size (2types; 2700, 3000V) .
- DSS-272M and DSS-302M each correspond to 1200V rms 3seconds or 1000V rms 1minute and 1500V rms 1minute AC withstanding voltage tests respectively.
- Quick response for surge voltage and low limiting voltage.
- Small capacitance and excellent insulation resistance (100MΩmin)
- Stable for repeated discharge test conditions and environmental fluctuation.
- No polarity.
- No dark effect.
- This Series are recognized under UL1449, CSA and TÜV.
- Operating temperature limit : -40 ~ 85°C
- Storage Temperature Range : -55 ~ 125°C
