- TVA-05V GNSS Surge Protector
The TVA-05V is a surge protector designed by Furuno specifically for GNSS timing receivers. Supporting L1, L2, and L5 bands along with DC pass, it protects time synchronization systems from electrical surges caused by lightning strikes, making it ideal for long-term critical infrastructure operations.
• System Protection: Lightning surge protection for GNSS timing receivers, active GNSS antennas, and critical infrastructure timing systems.
• Network Infrastructure: Essential for 5G telecommunications, power grids, broadcasting, and PTP/NTP systems that demand long-term timing stability.
• System Compatibility: Optimized for use with Furuno GNSS receivers and antennas, including the GT-100 and AU-500 series.
• Standard Compliance: Meets IEC 61643-21 (JIS C 5381-21) Category C2 standards for lightning surge protection.
• Ruggedized Design: IP67-rated waterproof construction, built to withstand harsh outdoor environments and long-term deployment.
• Active Antenna Support: Features DC pass-through, allowing power to reach active GNSS antennas while maintaining signal integrity.
