Tenders Are Invited For Power Converters - Acquisition Of A Static Current Converter in Hungary

Work Detail

Power Converters - Acquisition Of A Static Current Converter. The Proposed Static Or Auxiliary Current Converter Device Must Be Suitable For Battery Charging In The Voltage Range Of 24-36 V With A Dc 600/750 V Overhead Line Network Voltage (The Setting Depends On The Auxiliary Operating Voltage Level Of The Given Vehicle), As Well As For Supplying The Auxiliary Operating Network At The Maximum Voltage Setting Even In The Case Of A Continuous Load Of 200 A (Expected Useful, Maximum Output Power: 7.2 Kw). The Device Housing Should Be Designed With An Ip 65 Enclosure. The Battery Is Charged And The Auxiliary Power Supply Is Supplied Directly From The Overhead Line. The Recommended Type Should Ensure Gentle And Reliable Charging Of The Battery With A Small Current Fluctuation (In Accordance With Din 41773). It Must Be Possible To Start The Equipment Even Without The Existence Of A Counter Voltage, The Battery Charging Equipment Must Also Operate In The Case Of A Deeply Discharged Battery (Blackstart Function). The Device Must Typically Have The Following Properties: Operating Voltage Range Dc 400V – 900V Switch Off Automatically If The Mains Voltage Is Dc < 400V Or Dc > 900V Switch Back Immediately If The Input Voltage Has Reached The Permitted Range Inputs And Outputs Are Voltage-Free For The Housing And Body, Electrical Insulation Requirements Have A Fully Galvanically Isolated Output According To En 50124-1 Standard Should Have Free-Flow Cooling, Without Moving Parts, A Cooling Fan In The Interior Of The Device Cannot Be Used Without A Battery, The Converter Must Start (Without The Counter Voltage Of The Battery) As Long As The Necessary Input And Overhead Line Voltage Is Present. Have Outputs With Permanent Short-Circuit Strength, It Must Be Able To Sustain The Delivery Of The Maximum Dc Output Current Even At The Lowest Input Voltage And The Maximum Permitted Temperature Dc Output With A Maximum 1% Pulsating Current (Peak-To-Peak) And A Maximum ± 1% Voltage Level Fluctuation. The Charging Current Of The Battery Can Be Parameterized, It Must Be Adjustable If The Parameterization And Setting Is Done Via Serial Line, Via Software (Type Of Battery Cells (Acidic Or Alkaline), Number Of Battery Cells, Etc.), Parameterization Software Must Be Free Of Charge, For Its Use, The Bidder Must Be Given An Instruction Booklet (Which Parameters Can Be Set And How To Set Them (Electronically And In 1 Copy)) And 3 Serial Line Cables Necessary For Parameterization Upon First Delivery. The Device Must Be Suitable For Charging Both Acid And Alkaline Batteries, And Must Have A Separate Charging Branch. The Device Must Have An Output Indicating Its Operation, The Device Housing Must Be Made Of Stainless Steel Or Aluminum, Painted Or Colored. The Dimensions Of The Space Available For Placing The Auxiliary Power Converter On The Vehicle (The Specified Dimensions Cannot Be Increased In Either Direction, Otherwise
