The range of DC to DC power supplies is designed for powering undersea repeatered cable systems requiring very high reliability and control. At the heart of the product is a 3kW DC to DC converter, based around a switch mode push-pull topology operating at a switching frequency of 20kHz. Utilising the latest power mosfet technology, efficiencies of 89% are achieved. The use of digital signal processing technologies enables a single control loop to provide a ‘seamless’ transfer between a constant current mode and a constant voltage mode, and to enable a high degree of user control enabling a current regulation characteristic of better than 0.2% over the full voltage range. Very high availability is achieved through a unique method of duplicating strategic circuits. Additionally, the design has a low component complexity and is modular in construction to minimise repair time. Two power units operate independently – both capable of the total output current, but only supplying half the current in a normal configuration. In the event of a failure in one unit, the second is designed to take over – thus supporting the full load. A unique switching unit allows safe access to the depowered unit for any maintenance. All control is carried out from the front panel. Consisting of an ergonomically designed membrane containing tactile keys and a 10.4 inch thick film transistor TFT display, it invites the user to operate the equipment through its use of a carefully designed graphical interface with a simple to understand menuing structure. Control of voltage, current, ramping, alarms, polarity, routing and many other features are available. A QB3* interface is incorporated into each power unit for network monitoring via a Submarine Management System (SMS). Various management scenarios can be facilitated by the SMS. The equipment is designed to power into a cable system. However, a variable test load is incorporated to enable testing without access to the cable. The load can be varied over the full range of the power feed. The unit is housed in a separate cubicle together with facilities for terminating optical fibre cables and monitoring system and station earths. The flexibility of the standard power feed equipment allows for adaptation to various optional system configurations according to specific project requirements.

Company Details

Formed from the merger of Alcatel and Lucent Technologies, Alcatel-Lucent combines two entities that share a common lineage that can be traced back to 1986, when Alcatel’s parent company, CGE (la Compagnie Générale d’Electricité), acquired ITT’s... more
