PHL-T-RJ11 Network SPD（Telephone network）
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）
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.
PHL-TA-1000PA
DC Surge protective device (Solar Photovoltaic)
Product overview
The secondary photovoltaic DC surge protector is a device specifically designed to protect the DC photovoltaic power inside the combiner box of a solar photovoltaic system. Its main function is to prevent equipment damage or malfunction caused by surges or electromagnetic interference in photovoltaic systems.
This type of protector usually follows relevant testing standards, such as EN 5053911 and GB/18802-31 as you mentioned. These standards specify the technical requirements and performance indicators that protectors must meet to ensure that they can effectively protect photovoltaic systems from the effects of surges and surges.
PHL-S24-L2-Ex 24V Voltage System (Intrinsi...
Product overview
The PHL-S series SPD is a device designed specifically to protect field equipment such as transmitters, switches, frequency signals, communication equipment, TC, RTD, etc. It can be applied to I/O, DCS, PLC and other equipment in the control room, which are usually connected using two wire and three wire systems. Therefore, effective protection is needed to prevent the impact of lightning impulse voltage or operation over-voltage.
PHL-S24-L2 24V Voltage System SPD
Product overview
The PHL-S series SPD is designed specifically for protecting on-site equipment in control rooms, including transmitters, switches, frequency signals, communication equipment, TC, RTD, as well as I/O, DCS, PLC and other equipment. These devices are usually connected using two wire and three wire systems, and the use of SPD is necessary to prevent damage caused by lightning impulse voltage or over-voltage during operation.
