Glass Gas Discharge - RL302 Series
Features
• Compared with other surge absorbers having
similar functions has the fast response speed ,largest
withstand current and voltage but smallest size.
• All electrical characteristics are very stable even after
long period of charge and discharge. There is no need
for inspection and exchange periodically.
• Super capability to withstand repeated lightning
strikes.
• Stable and very Small electrostatic capacitance
(<0.8pf) and great isolation (>100MΩ).
• No pollution material.
• Bilateral and symmetrical.
• Completely insensitive to weather, temperature,
humidity and lightness.
Applications
• Power Supplies
• Motor sparks eliminating
• Relay switching spark absorbing
• Data line pulse guarding
• Electronic devices requiring UL497A and UL497B
compliant
• Telephone/Fax/Modem
• High frequency signal transmitters/receivers
• Satellite antenna
• Radio amplifiers
• Alarm systems
• Cathode ray tubes in Monitors/TVs
