Juice Goose LD-75 Data Sheet

Data Line Protection

For POE Applications

The LD-75 is designed to protect
eight wire data circuits with
communication rates up to
HDMIBaseT at power levels up to
75V.

LD-75

The LD-75 provides silicone avalanche diode (SAD) protection against potentially dam­aging surges resulting from lightning strikes near equipment installations. Protection is
provided to all eight conductors with RJ45 connections.

The unit design includes line to ground protection with a ground line conductor that
safely diverts potentially damaging energy surges.

This device is rated for operating voltages up to POE levels and has a breakover
(protection) threshold of 75 volts. It has a low capacitance design that has been tested
to a 1Gb transmission rate with a BERT error rating of 1.5% - sufficient for HDBaseT.

Installation

RJ-45

GND

Unprotected Line

User equipment plugs into the protected side of the LD-75 (“EQUIP”). The source data line plugs into
the unprotected side (“LINE”). The green wire (“GND”) must be bonded to the protected equipment
power ground (third wire safety ground). Keep the ground wire as short as possible. Adding length to
the ground increases the resistance of that line and reduces the effectiveness of the protection.

Never install data wiring during a lightning storm.

Disconnect data lines before installing the LD-75.

This protector is intended for indoor use on communication loop circuits that are isolated from the
Public Switch Telephone Network.

Low voltage, communications loop circuits should not be exposed to accidental contact with high
voltage conductors, such as lighting or power lines. This protector should be installed per applicable
requirements of the National Electric Code and related local codes and ordinances.
