Signal surge protector
Industrial DB9 / RS232 Surge Protector – Reliable Serial Port Protection
Product Features
● Fast response;
● Low insertion loss, making sure that there's no interference of signal transmission;
● High current flux with strong capability of discharging huge surge
● High-quality fast clamping semiconductor with accurate clamping voltage.
Scope of Application
Looking for a dependable solution to protect your serial communication assets? Our specialized DB9/RS232 Surge Protector is the ultimate defense mechanism for all your serial port devices against unexpected lightning strikes and electrical surges.
Why Choose Our Serial Surge Protector?
Universal Compatibility: Seamlessly integrates with all standard DB9 and RS232 interfaces used in PLC, CNC, and industrial networking.
Quick & Reliable Wiring: Engineered for hassle-free installation, saving you time while ensuring a rock-solid connection.
Advanced Surge Suppression: When high-voltage surges threaten your system, the device instantly diverts the destructive current straight to the earth ground. This limits the output voltage to a perfectly safe threshold, keeping your downstream devices completely unharmed.
Whether you are managing a manufacturing plant, a server room, or automated systems, this compact yet heavy-duty protector prevents data corruption and hardware failure. Invest in reliable protection and keep your data flowing safely.

Quality Inspection(Test reference)
1 Inspection Reference
IEC61643.11 Surge Protective Devices (SPD) for Low-Voltage Distribution Systems
Part 1: Performance Requirements and Test Methods
GB/T 2828.1-2012 Sampling Inspection Procedures
Part 1: Sampling Plans for Inspection by Acceptance Quality Limit (AQL)
2 Incoming Inspection
Incoming material inspection is conducted based on the "Metal Parts Inspection Standard," "Plastic Parts Inspection Standard," "Electronic Parts Inspection Standard," "Auxiliary Materials Inspection Standard," and the GB/T 2828.1-2012 Sampling Inspection Procedure.
3 Finished Products Inspection
1) Routine test
Routine inspection is a 100% inspection conducted at the final stage of production on products from the production line. After inspection, no further processing is done, except for packaging and labeling.
2) Sampling test
Sampling inspection is performed according to the GB/T 2828.1 sampling standard.
3) Acceptance test
Verification inspection is a sampling inspection conducted to ensure that the product continues to meet the standard requirements. Verification inspection should be carried out according to the procedures and frequency specified by the standard.
