BORDLINE® M7 AC 400-480VFor diesel-electric locomotives

The BORDLINE® M7 AC battery charger is a compact, rugged unit to generate supply voltage for rail vehicles.

System overviewThe BORDLINE® M7 AC converter is based on modern IGBT technology.

The system is composed by:• FRectifier and EMI filter for 480 and 400 Vac

inputs• Rectifier, EMI filter and step-up (Power Factory

Control) for 230 Vac input (option)• Crowbar (1000 Vdc)• Insulation transformer: insulate the mains to the

load for safety requirements satisfaction• Control unit• Rectifier and output filter

FunctionalityThe BORDLINE® M7 AC battery charger feeds from a threephase inverter inside the loco (480 Vac 3ph 60 Hz, 400 Vac 3ph 50 Hz) to generate a DC voltage (24 Vdc to 28,8 Vdc) to charge the batteries and supply the DC loads of the vehicle.

Characteristics• DSP technology• Compact and robust design• Two voltage inputs (480 Vac 3ph 60 Hz, 400 Vac 3ph

50 Hz); option (230 Vac 1ph 50 Hz)• Liquid cooled system• Ethernet diagnostic• Rack mounting• High reliability thanks to consolidated building blocks

Control and monitoringThe converter is full digital controlled (DSP technology). The monitoring of the converter is supported by Ethernet interface (via M12 connector). A web server, compatible with the most common browsers (e.g. Internet Explorer) provides monitoring of the converter status (main technical parameters, alarms codes, etc). There‘s also a four channel 4-20 mA to provide information (batteries voltage and current) to the train diagnostic.

Cooling systemThe unit is liquid cooled. The battery charger is located inside an electrical cabinet where there‘s a ventilation of filtered air when the train is running.

Mechanical designThe converter is suitable to be mounted on board inside a cabinet. All electrical interfaces are located in the front for easy and fast connection.

Diagnostics and serviceThe service-friendly modular design with highly standardized components ensures high reliability, excellent spare parts availability, and optimized life cycle costs. For maintenance, a diagnostic interface (Ethernet) is available. It permits to monitor converter status and alarms history.

Application exampleBORDLINE® M7 AC is mounted on electric and electro-diesel locomotives running in Europe and South America.
