Features and highlights
The Alerton ESD-100 is an Ethernet data line protector, which protects
equipment connected to unshielded twisted pair (UTP) Ethernet networks
from transient voltage. Use the ESD-100 on 10Base-T or 100Base-TX
Ethernet networks.
The ESD-100 is a low capacitance, two-stage transient voltage
protector that provides primary and secondary protection against
lightning, inductive switching, and electrostatic discharge (ESD). The first
stage directs the transient current through the ground terminal return path,
and the second stage clamps the voltage to a safe level without
interrupting service.The ESD-100 is designed to protect circuits from
common-mode (line-to-ground) and differential (line-to-line) transients.
An RJ-45 modular jack provides a simple connection to the network,
and a pigtail lead with an RJ-45 plug provides connection to the protected
equipment. For maximum protection, a 14 AWG grounding wire provides
connection to a known good earth ground at the equipment panel.
A keyhole mounting system on the back of the unit simplifies
installation.
Use the ESD-100 in combination with the BTI-S global controller in
smoke control applications. Also use it to protect equipment in harsh
environments where electrical transients are common.
