Overview

SUNIX RS-232 Surge Protector is an appliance designed to prevent damage to your electrical equipment from power surges and spikes. It contains avalanche diodes, one for each line. All diodes are returned to a ground stud. SUNIX RS-232 Surge Protector is provided with a 2-foot ground wire and has male and female DB9 connectors.

SUNIX RS-232 Surge Protector built-in PTC thermal fuse ensure instantaneous reaction to lightning strikes and wiring faults. If the surge components are damaged due to power spike or over voltage, excess power can not reach your equipment. Unlike the SUNIX RS-232 Surge Protector, most surge suppressors continue to let power through even after circuits have been damaged, leaving your equipment exposed to other damaging surges.

SUNIX RS-232 Surge Protector's fail safe, which means that once the circuit of an SUNIX RS-232 Surge Protector has been compromised the unit disconnects equipment from the power supply ensuring that no damaging surges reach your equipment. SUNIX RS-232 Surge Protector is a cost-efficient solution to the problem of potential equipment damage from induced transients on RS-232 COM ports of PC or laptops/notebook.

Description

The Sunix RSP1000 is engineered to provide dependable surge protection for RS-232 serial communication equipment operating in environments where electrical disturbances may occur. It protects connected equipment from voltage spikes caused by lightning, switching events, and other transient electrical conditions that can damage sensitive serial interfaces.

Each RS-232 signal line is protected by dedicated 600W peak surge protection using avalanche-diode technology, providing rapid response in less than 1ns. An integrated PTC thermal fuse offers additional fail-safe protection by disconnecting the circuit if the protection components become compromised, helping prevent further damage to connected equipment.

The compact ABS enclosure features DB9 male and DB9 female connectors for simple inline installation without modifying existing cabling. A 600mm grounding wire allows proper connection to earth ground for maximum protection, making the RSP1000 suitable for industrial automation, security systems, laboratory equipment, manufacturing environments, and commercial serial communication applications.
