Protect Audio and Voice Systems from Lightning Surges
The SP-24DC10-RJ11 is a dedicated audio surge protector designed for PBX systems, emergency phones, fax lines, and other voice communication devices. Built to IEC lightning protection standards, it integrates a multi-stage discharge design to effectively suppress and dissipate surge currents in audio and telephony circuits, ensuring uninterrupted voice communication even during severe electrical events.
·Multi-Stage Protection for Critical Voice Lines
Equipped with gas discharge tubes, MOVs, and TVS diodes, the SP-24DC10-RJ11 delivers comprehensive surge suppression with a fast 1 ns response time. With a 5kA surge capacity, it reliably diverts transient energy away from sensitive endpoints, preventing equipment damage and maintaining clear, stable audio transmission.
·Compact, Durable, and Easy to Install
Designed for inline installation with RJ11 connectors, this model requires no external power supply. Its aluminum alloy housing improves heat dissipation and fire resistance, while the compact footprint makes it suitable for deployment in telecom racks, control cabinets, or field installations where space is limited.
Applications
1.PBX & Telephone Systems — Protect analog and VoIP trunk lines from surge-induced failures.
2.Emergency Telephones — Ensure reliable operation of safety-critical voice communication devices.
3.Fax & Modems — Defend legacy communication hardware from transient overvoltage.
4.Public Address & Audio Systems — Maintain consistent voice signal quality across facilities.
