2024-04-25

Product overview

Field Instrument Surge Protective Devices is a device used to protect on-site instrument equipment from the impact of surges. In industrial control systems, sudden surges or electromagnetic interference may cause damage or malfunctions to instrument equipment, so the role of surge protectors is very important.

The intrinsically safe explosion-proof certification ensures that these devices can be safely operated in potentially explosive atmospheres, minimizing the risk of ignition and explosion. This certification is crucial for industries such as oil and gas, chemical processing, pharmaceuticals, and others where safety is paramount in hazardous environments.

PHL-T-RJ11 Network SPD(Telephone network)

2024-04-26

Product overview

Network SPD (Surge Protective Device) is a device used to protect telecommunications systems from electrical interference such as sudden voltages, surges, and lightning strikes. They are usually installed at the input end of telecommunications lines to prevent overvoltage damage to sensitive equipment or systems.

The telecommunications system includes telephone lines, data lines, network lines, etc., which often face threats from natural disasters such as lightning, and therefore require appropriate protective measures. The function of network SPD is to guide the sudden voltage introduced in the telecommunications system to the ground when it reaches a dangerous level, in order to protect the equipment from damage.

When installing network SPD, it is important to choose products that are suitable for the characteristics of the telecommunications line and follow the manufacturer's instructions for proper installation. This can ensure that the telecommunications system can effectively protect equipment in sudden events such as lightning, ensuring the stability and reliability of communication.

PHL-T-RJ45 Network SPD(Ethernet network)

2024-04-26

Product Overview

Network SPD typically has a standard RJ45 interface, which is suitable for connecting network lines to switches, workstations, and various network communication devices. When electrical interference such as sudden voltage or lightning strikes enters the network line, the network SPD quickly directs these interferences to the ground to protect the devices connected to the network from damage.

When installing a network SPD, it is usually inserted into the input of the network line to prevent overvoltage from spreading through the network line to the connected devices. This can ensure effective protection of network equipment in sudden events such as lightning, and improve the stability and reliability of the network.
