MTL DP200 BT & RJ range

Lightning surge protection for modems and telemetry equipmentsignal and data cabling

• Protects fax, modems, telemetry and other telecom equipment

• Robust — 10kA surge capability

• BT or RJ11 style plug and socket

• Full 4-wire protection

• Immune to power crossing

• RFI version available for noisy environments

The DP200 BT & RJ range of safeguards modems, telemetry outstations and fax machines from induced surges and transient overvoltages caused by lightning and other electrical disturbances. A single lightning strike can easily damage or destroy unprotected equipment and lead to expensive and disruptive system downtime.

Telecom authorities now encourage 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.

Hybrid surge protection circuitry is utilised within the DP200 BT & RJ range 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/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.

These robust devices, with a 10kA surge handling cabability, come with either a BT style plug and socket (DP200/BT and DP200/BT/RFI) or an RJ11 plug and socket (DP200/RJ and DP200/RJ/RFI). These self contained units have been specifically designed for use on Public Switched Telecom Networks (PSTN) offering full 4-wire protection.

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 2.5mm2 cable. This cable is screwed into the unit’s earth terminal and the other end is connected to the earth of the protected equipment.

Complete protection can be achieved using the MTL range of ac power surge protection devices to prevent surges entering equipment via their power supply. The MA05 and MA10 range combines a high level of protection with the benefit of RFI filtering thus removing noise and other unwanted signals from the supply.
