Tenders Are Invited For Uninterruptible Power Supplies - Reconstruction Of Uninterrupted Power Supply Systems

Uninterruptible Power Supplies - Reconstruction Of Uninterrupted Power Supply Systems. In Mavir Zrt.S Telecommunications Premises, Uninterruptible Power Supply Systems, Individually Built For Individual Needs, Ensure The Safety And Continuity Of The Power Supply. The Fundamental Reason For The Unique Design Was To Keep Complete Modularity In Mind, Which Enables, In Addition To Holistic Design, Changing And Developing Platform Systems Not To Reduce The Usability Of Uninterruptible Power Sources. In Addition To Platform Independence, The Possibility Of Plastic Performance Expandability Also Arises As A Basic Need, Thus Meeting The Extremely Fast And Constantly Changing Info Communication Needs. Taking Into Account The Redundancy, The 48V Dc Voltage Is Currently Provided By 2 Parallel 19 47U High Rack Gamatronic Sc1-Udc+ Charging Controllers With A Hot-Swap System And The Gamatronic Hpsuv 48V-33A Llc-N 50/60 Type Equipment. There Is A Demand On The Sites To Increase The Battery Capacity, Which Is Currently Only Possible By Placing Additional Racks Or Battery Cabinets, Which In Many Cases Cannot Be Solved Due To A Lack Of Space, And The Acquisition, Installation And Connection Of The Rack Cabinets Is An Extra Cost. In Addition To The Above, An Increase In The Number Of Batteries Must Also Be Taken Into Account, Which May Even Require Static Calculations For Some Properties. With Regard To - Can Be Made For Equivalent Services. Charging Controller And Charging Drawer For 22-24 Units: - 44 Dc 48V 12Kw Power Hot Swap Shelf Charging Controller And Charging Drawer (19 Wide And Maximum 3 Units High) - 10 Dc 48V 24Kw Hot Swap Shelf Charging Controller And Charging Drawer (19 Wide And Maximum 4 Units High) - Charging Controller And The Allocation Of Rear Fixed Copper Rail Connectors Of The Hot Swap Shelves Of Charging Drawers Should Be The Same As That Of The Currently Designed Gamatronic Charging Drawers (For Example, Enetek Modulflex Family Or Equivalent Devices). Conversion Of The Copper Current Conductors Inside The Rack And The Installation Of Additional Connection Points Are Not Allowed. - The Charging Controller Should Communicate With The Batteries, Thus Optimizing The Charging Process Of The Batteries, Increasing Their Service Life. - The Charging Controller And Charging Drawer Module Must Have Overvoltage Protection. - The Status Of The Dc 48V Power Supply System Can Be Monitored Online Via Snmp. - The Dc 48V Power Supply System Should Be Able To Send Snmp Traps For Errors, Which Should Match The Zabbix System Of Mavir. Batteries For Places 32-47 Units - 90 Units 19 Wide Maximum 4 Units High Dc 48V Minimum 100Ah Or More Lithium-Iron-Phosphate Battery Group With A Maximum Capacity Of 20% More (Lfp Or Lifepo) One Battery Pack S
