Technical Specifications
The tram is largely made out of aluminium, with a welded underframe to which the body framework is bolted in sections, which means that the Combino can easily be adopted to different lengths, widths and gauges. The length of the trams varies from 19 metres (62 ft) (Nordhausen "Duo" and Melbourne D1) to a world record 54 metres (177 ft) (Budapest), accommodating between 100 and 250 passengers. All versions are designed to have a 300-millimetre (11.8 in) floor height and a 10-tonne (11-short-ton) axle load. It can be built as a one-way or a two-way vehicle, and it is also produced as DuoCombino with an additional diesel propulsion system.
They usually take 600V DC overhead power and convert this to 400V 3-phase AC power for the regenerative low wear motors via 3 IGBT PWM inverters. On board controls, lighting and air conditioning run at 24V DC.
