Applications:

• Train, Metro and Light Rail, on board rail vehicles auxiliary power converters, battery charging, air conditioning, communication, train management systems.
• Railway and mass transit systems, signalling, track switching, communications, tunnel emergency lighting, security, CCTV surveillance and control centres and trackside services.

TT Transportation technology, auxiliary power converters, inverters and battery chargers for use on board all types of rail and other mass transport passenger vehicles and locomotives. Converters are custom designed for use on AC and DC catenary voltages up to 3000V or on third rail 750V DC service lines. The converters can be produced to deliver single or multiple AC outputs 3 phase, single phase 50Hz, 60Hz or 100Hz and combined with DC battery charging facilities.

CETACT 2
A range of 19 inch rack mounting DC to DC converters which has been developed for use on light rail vehicles, trams, trolley buses and metro cars for use with the on board communications systems and other auxiliaries where a stabilised 24 volts DC or 48 volts DC is required.
The CETACT 2 units have been designed for installation in the Siemens Deuwag trams as mechanically and electrically interchangeable converters as substitute replacements for the originally as built tram equipment.

WMR Series Heavy duty, modular ruggedised DC to DC converters providing galvanic isolation, transient protection, voltage conversion, stabilisation and regulation for use on board all types of rail vehicles and locomotives for UHF/VHF microwave transmitters and receivers, voice/data radio equipment, isolation from 24v, 36v, 48v and 110v batteries. These products provide a regulated output voltage to all types of critical loads irrespective of the discharge recharge cyclic status of the connected battery.
