DSS
Features
•High DC spark-over voltage in spite of compact size (2types; 2700, 3000V) .
•DSS-272M and DSS-302M each correspond to 1200volts rms 3seconds or 1000volts rms 1minute and 1500volts 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 UL 1414, UL1449, CSA and TÜV.
