DP200 BT & RJ telecom

surge protection devices

Lightning surge protection for modems and telemetry equipment

connected to Public Switched Telephone Networks

The DP200 BT & RJ series safeguard

modems, telemetry outstations and

fax machines from induced surges

and transient over voltages caused

by lightning and other electrical

disturbances. A single lightning strike

can easily destroy unprotected equip-

ment and lead to expensive down-time.

Telecom authorities now encour-

age the end user to fit secondary

protection for their equipment. Telecom

providers may supply some simple surge

protection such as a gas discharge tube

at the customers’ premises. However, this

is generally only to protect the telephone

line itself and offers little or no protection

for any equipment attached to it.

Surge protection – the facts

Many kinds of process control instrumentation and communication networks can be destroyed by surges (also referred to as “transient over-

voltages”) on power, signal and telecommunication lines. This invariably results in expensive downtime. Surges may be caused by lightning,

heavy electrical load switching, electrical faults or electrical ‘noise’, from arc welding and other industrial sources. Those induced by

lightning are on the increase globally, and it is recognised by European and other international standards that lightning can induce voltage

surges of more than 10kV on equipment cables - and a ‘near miss’ can inject more than 5kA of current through electronic circuitry.

The only effective way of preventing such damage is to equip all vulnerable connections with surge protection devices (SPDs). These

incorporate circuitry designed to divert surges safely to earth, and to control the voltage seen by sensitive equipment. The Telematic range

includes SPDs for virtually all applications, including mains power supplies, process instrumentation, PSTN installations and computer

networking, thus providing ‘all-round’ protection from one source. These products are available directly from Telematic and from distributors

around the world. Further information on all aspects of surge protection can be found in Telematic’s range of Technical Application Notes

available by post or downloaded from our Web Site.

Protects fax, modems, telemetry and

other telecom equipment

Robust - 10kA surge capability

BT or RJ11 style plug and socket

Simple installation

Full 4-wire protection

Immune to power crossing

RFI version available for noisy

environments

Hybrid surge protection circuitry is

utilised within the DP200/BT & DP200/RJ

to provide the best protection devices

currently available. Should mains voltages

be applied to the telecom line, for example

by falling cables, the DP200 BT or RJ unit’s

power crossing immunity prevents damage

to both the telecom equipment and the

protection device.

The DP200 BT & RJ devices are easy

to install. Simply loosen the lid retaining

screw, remove the lid and screw to a wall or

panel. The unit should be earthed with

2.5mm

the unit’s earth terminal and the other end is

connected to the earth of the protected

equipment.

cable. This cable is screwed into

The DP200/BT/RFI & DP200/RJ/RFI

provide RFI filtering in addition to

protection from lightning induced

overvoltages. These devices suppress

interference due to medium wave radio

transmissions, and other sources, which

can compromise normal telecom

operation.

Complete protection can be achieved

using Telematic’s range of ac power

surge protection devices to prevent

surges entering equipment via their

power supply. The MA05 and MA10

range combine a high level of protection

with the benefit of RFI filtering thus

removing noise and other unwanted

signals from the supply.
