SP-24DC10-RJ11 is 24V Audio Surge Protector. It is designed and manufactured according to IEC lightning protection standards. It adopts a multi-stage discharge component design, effectively suppressing and dissipating surge currents in voice communication lines.
No external power supply is required. Install in series by connecting the protected device to the OUT port, the network line to the IN port, and the ground wire to a grounding busbar or point.
When a surge enters, excess voltage is absorbed and discharged through primary discharge, voltage limiting, and voltage clamping, ensuring only a safe voltage reaches network devices.
1. Multi-Component Surge Protection – Built-in gas discharge tube, varistor, and TVS diode for comprehensive protection.
2. Ultra-Fast Response – Reaction time of up to 1ns ensures rapid surge suppression.
3. High Surge Capacity – Can handle surge currents up to 5kA.
4. Durable Aluminum Alloy Housing – Lightweight, aesthetically designed, and optimized for heat dissipation.
5. Compact Design – Ideal for installation in limited spaces.
Suitable for various audio devices, including PBX systems, fax machines, modems, emergency telephones, and trunk lines.
