DSA Series
The DSA Series has a wide lineup of DC spark-over voltages and has excellent AC withstand voltage to protect the electrical circuits of various AC power sources.
Useful informationFeatures
- The Models of this Series are extensively used as surge-protecting elements for electronic equipment in low-voltage and low-current circuits such as telecommunication equipment and sensor lines.
- Excellent for protecting signal lines that require low capacitance.
- The DSA-A-type combined with varistor or a cement resistor can be used as surge-protecting elements in power supplies.
- Allows performing the AC withstanding voltage test without removal of the surge absorber.
- DSA A-type Series displaying the “MMCC”trademark (except 402MA, 452MA)are UL-recognized protectors when connected to the appropriate varistor (UL recognized) or a cement resistor (RGBS5 3ΩK) in-Series. (UL1449 File No.E318314 )
