PDDP Series Data Line Surge Protection

Ideal for LAN Hubs, Concentrators, and Multiport Interfaces

The PDDP Series of data communication line protectors will ensure the reliable operation of hubs, bridges, routers, switches and other networked equipment running 10Base-T and 100Base-T Ethernet, RS-422, RS-423, RS-232, Analog Dial-up, CSU/DSU, DDS, ISDN, T1 and most other communication environments.

PDDPs Offer:

• State-of-the-art, avalanche diode and thyristor technology.
• Compact, in-line installation.
• High-speed, high-energy handling capability.
• Low shunt capacitance to reduce signal loss.

You Receive:

• Affordable, superior, equipment protection.
• Improved reliability and maximized system up-time.
• Protection at the interface card.
• Adaptability to most industry applications.

Transient surges can enter electronic equipment through any pathway provided. If a facility has a reliable ac power protection system in place, transient surge energies can still be generated within a building by sources such as inductive load switching, ground loop currents and electrostatic discharge. These surge energies are clamped by the ac power protector into the communication ground, damaging expensive communications hardware.

Eaton protectors are specifically designed to give added security to electronic devices with extremely low tolerance for voltage rises or ground loop energies. This protection is particularly important for equipment networked at distances greater than 30 feet (9 m) and installations in high lightning areas.

PDDP models protect virtually any communication interface including: 10Base-T and 100Base-T Ethernet, RS-422, RS-232, RS-423 and most high-speed LAN/WAN interfaces. Combined into a compact interface unit, the devices exhibit an extremely fast response time of less than 5 nanoseconds.

All these features make PDDP protectors the most cost-effective and versatile devices of their kind available today. Whether you need to protect a single communication line, or an entire installation, Eaton’s PDDP Series protectors are an easy, cost-effective solution to overvoltage problems.

Installation

To install, insert the protector in series between the incoming communication line and the I/O port of the equipment to be protected. The protector ground wire must be connected to the metal chassis of the equipment being protected. Units should be installed at both ends of the data cable for the most effective protection.
