What the buyer is looking for
In the telecommunication premises of MAVIR Zrt., individually built uninterruptible power supply systems ensure the security and continuity of power supply. The basic reason for the unique design was to keep full modularity in mind, which allows, in addition to holistic design, that changing and developing platform systems do not reduce the usability of uninterruptible power sources. In addition to platform independence, a basic need arises for the possibility of expanding plastic performance, thus meeting the extremely fast and constantly changing infocommunication needs. Due to the redundancy, currently the Gamatronic SC1-UDC+ charge controller and the Gamatronic HPSuV 48V-33A LLC-N 50/60 type equipment with a hotswap system built into a parallel 2pcs 19" 47U high rack cabinet provide the 48V DC voltage. On the sites, there is a need to increase battery capacity, which is currently…

… only possible by placing additional rack or battery cabinets, which in many cases cannot be solved due to lack of space, and the purchase, installation and connection of rack cabinets is an extra cost. In addition to the above, in the case of the expansion of the number of batteries, an increase in weight must be taken into account, which may require static calculations for some properties. 1.) Means to be procured In the procurement documents, the reference to specific services was made only in order to define clearly and intelligibly the nature of the subject-matter, a tender may be made for the services required or equivalent in terms of its technical parameters. In addition to the reference, ‘or equivalent’ is always understood. Charging control and charging drawer for 22-24 units: - 44 DC 48V 12kW hot swap shelf charge controllers and charging drawers (19" wide and up to 3 units high) - 10 DC 48V 24kW hot swap shelf charge controllers and charging drawers (19" wide and up to 4 units high) - Charging control and charging drawers hot swap shelves with rear fixed copper rail connectors are allocated in the same way as the currently designed Gamatronic charging drawers (e.g. ENETEK Modulflex family or equivalent devices). - The charger controller communicates with the batteries, thereby optimizing the charging process of the batteries, increasing their lifespan. - The charge control and charge drawer module should have overvoltage protection. - The state of the DC 48V power supply system can be monetized online via SNMP. - The DC 48V power supply system for faults should be able to send SNMP traps that match the MAVIR Zabbix system. Batteries for 32-47 units locations - 90 x 19" wide up to 4 units high DC 48V with a minimum capacity of 100Ah or up to 20% higher Lithium Iron Phosphate Battery Group (LFP or LiFePo) The weight of a battery pack should not exceed 65kg. - 40 19" wide maximum 4 units high DC 48V minimum capacity of 150Ah or maximum capacity of 20% higher lithium iron phosphate battery pack (LFP or LiFePo) One battery pack shall not weigh more than 90kg. 2.) Installation activity conditions The above devices are exchanged by the contractor at MAVIR 27 locations (in different parts of the country). The duration of work should not exceed 2x8 hours, and only one uninterruptible power supply cabinet can be discharged at a time. Workers shall be provided with an external 48V DC uninterruptible source of equipment for the duration of the de-energisation. A minimum of 2 people with 48V DC uninterruptible power supply installation and professional FAM training are required. 3.) Warranty conditions For charging controllers and charging accounts, the expected warranty is a minimum of 24 months after proof of completion. In the case of batteries, the expected guarantee is the yoke of performance
