1540 Series Outdoor PoE Ethernet Surge Protector
The Bourns® Model 1540 Series Outdoor PoE (Power over Ethernet) Surge Protectors incorporate state-of-the-art gas discharge tube and
surge limiting technologies to provide the highest protection level offered by Bourns. The Model 1540 Series is designed to meet applicable
Telcordia GR-1089 Level 1 and Level 2 Surge and AC Power Fault specifications on the data signal line while allowing operations up to
35 watts (employing both Mode A and B combination) at 57 volts. The Model 1540 Series enclosure is manufactured with a high impact
resistant, flame retardant plastic and is designed for harsh environments.
Characteristics
Test methods per UL 497B, GR-1089, CSA C22.2, IEC 61000-4-5, and IEEE 802.3at.
