Transtector ALPU-F140

Data Surge Protector SPD ALPU Outdoor Gigabit Ethernet/PoE++ Shielded RJ45 SASD, GDT CE Compliant, EN/IEC 60950-1, UL 497B

Transtector Gigabit Ethernet/PoE++ surge protector / arrester (also known as data line surge protection device or SPD as well as transient voltage surge suppressor or TVSS) ALPU-F140 is in-stock and will ship same business day as purchased from us directly. Our Gigabit Ethernet/PoE++ surge protector / suppressor provides protection for your electronic equipment and supports long-term system reliability by absorbing high amounts of transient energy. This industrial Gigabit Ethernet/PoE++ surge protection device for data line applications helps prevent damage from energy spikes that can be caused by lightning and other strong electrical power. The TVSS / transient voltage surge suppression device for Gigabit Ethernet/PoE++ can act as a lightning surge arrestor as well as an electrical overvoltage spike protection unit.

Surge protector device for dataline equipment part number ALPU-F140 from Transtector is designed to protect Gigabit Ethernet/PoE++ from transient voltage power spikes. This commercial Gigabit Ethernet/PoE++ surge protector provides high quality electrical surge suppressor protection. The data surge protection unit is rated for outdoor use. The outdoor Gigabit Ethernet/PoE++ surge protector is just one of many SPD products in-stock for same-day shipping.

This Transtector Gigabit Ethernet/PoE++ SPD uses a shielded RJ45 for connection. Our industrial Gigabit Ethernet/PoE++ lightning and transient surge protection for power spike suppression is part of the ALPU series. Gigabit Ethernet/PoE++ surge protector datasheet PDF of specifications and drawing with dimensions details for ALPU-F140 are available for download above.

Protection from surge for Gigabit Ethernet/PoE++ devices in this Transtector SPD component is in the form of Silicon Avalanche Suppression Diode (SASD) and Gas Discharge Tube (GDT). This data line TVSS uses Silicon Avalanche Suppression Diode (SASD) and Gas Discharge Tube (GDT) circuits to protect electronic devices from spikes. Transient voltage surge suppression from lightning and strong electrical spike events for Gigabit Ethernet/PoE++ are handled through SASD and GDT protection circuits in the data line SPD. ALPU-F140 commercial Gigabit Ethernet/PoE++ surge protection device is EN/IEC 60950-1 and UL 497B and .

Transtector provides one of the largest selections of same-day ship industrial power surge protection devices. Like our data surge protector SPD ALPU outdoor gigabit ethernet/poe++ shielded RJ45 SASD, GDT CE compliant, EN/IEC 60950-1, UL 497B, we ship our other electrical spike suppression equipment from in-stock inventory same-day as purchased. Transtector supports our customers with a sense of urgency while providing innovative power and signal solutions that ensure reliable operation of critical systems for a connected world.
