Characteristics
- Fast response time
- Low leakage current
- Low clamping voltage
- Wide range of voltages available
- Almost no energy consumption in stand-by mode
- After a surge impulse the varistor works immediately in normal mode so there is no slip current
- Excellent absorption at surge impulses
- Operating temperature:–40 ºC to +85 ºC for types up to 95 VRMS–40 ºC to +125 ºC for types from 115 VRMS
- Response time < 25 ns
- UL1449 3rd File E332875
- 14mm HighSurge and all 20mm Types greater or equal to 50Vrms are certified for use in Type 2 SPD applications (a few parts are still in progress)
- CSA File 224856
- VDE File 40016986 and 40016998 incl. IEC60950-1 Annex Q
Applications
- 12–48 VDC distribution
- 110–400 V power supply
- Leakage of voltage peaks
- Surge protection in accordance with EN 61000-4-5
