110V Audio Surge Protector

Reliable Surge Protection for High-Voltage Audio and Voice Lines

The SP-110DC10-2P is a purpose-built 110V audio surge protector designed to shield voice communication and public address systems from lightning surges and transient overvoltages. Manufactured to IEC lightning protection standards, it provides dependable defense for sensitive audio devices in both commercial and industrial environments.

·Advanced Multi-Stage Protection

Featuring a gas discharge tube, MOV, and TVS diode in a coordinated multi-stage design, the SP-110DC10-2P delivers rapid response within 1 ns and a surge capacity of up to 5kA. This ensures harmful voltage spikes are safely diverted to ground before reaching PBX equipment, amplifiers, or outdoor speakers—maintaining clear audio and stable system operation.

·Compact, Durable, and Easy to Deploy

The unit is designed for inline installation with a 2-pin power terminal (2P), making it simple to integrate into audio communication lines. Its aluminum alloy enclosure enhances heat dissipation and provides flame resistance, while the small footprint allows flexible placement in control rooms, telecom racks, or outdoor enclosures.
