• Description:
• Tenders are invited for Supply, Installation and Commissioning of 60kva Static Switch at Departure Baggage Belt Area, Bia, Katunayake 1 Item Supply, Installation and commissioning of 400V, 50Hz, 4 pole, 60kVA static transfer swich of State of the Art Technology with two inputs and an output, Built-in Maintenance Bypass System, Internal Wiring and all other standard accessories with fully enclosed compartment with standard protection and monitoring system as per the specification attached. 1 1 Item Supply and installation of 60kVA 3 phase isolation transformer with caster wheel mounted enclosure to the STS output Class H insulation. 480V to 480V and Dyn11. Also including necessary earthling installation Note:  Pls. quote only for European, UK, USA, Australian Makes. Other makes won't be considered for evaluation.  Supplier should be the Manufacturer authorised dealer or the local agent of the particular UPS make quoted  SriLankan Airlines will provide input and output DBs at site. 01 Output  Efficiency at Full Load: 99 %  Output Voltages: 400 V  Overload Protection shall be available  Rated Current Draw: 110A  Overload Capacity: 1.05 continuous 1.10 for 15 minutes 1.2 for 10 minutes 1.50 for 2 minutes 6 for 20 seconds 20 for 20 milliseconds  Transfer time: ≤5 ms typical  Unbalanced load conditions: up to 100% continuous current unbalance  Manual Bypass 02 Input  Input frequency: 45 - 65 Hz  Input Power: 60kW  Load Power Factor Range: 0.5 Leading and lagging  Load Capacity: 60kVA  Maximum Crest Factor: 3.5  Maximum Input Current: 110A  Maximum Line Current: 600A  Maximum permissible THDU for maximum upstream voltage: 15% continuous (without tripping of the protection devices)  Maximum upstream short-circuit current: 35 kA 03 Environmental  Operating Temperature: 0 - 40 °C  Relative Humidity: 20…80 %  Configurable input contacts for • Overload reset • Selection of Source 1 or Source 2 as the preferred source • Selection of the mode for automatic return transfer 04 Input and Output Contacts  Configurable output contacts for • Load drawing power (presence or absence of power to the load) • General alarm (fault on one of the sources or on the device) • Device alarm (device fault) • Source 1 "outside tolerances" or "within tolerances" • Source 2 "outside tolerances" or "within tolerances" • Source 1 active (SS 1 in ON-state) • Source 2 active (SS 2 in ON-state) • Source 1 or 2 selected as the preferred source • Overload 05 Configuration Options  ISX Central, SNMP, and TCP/IP compatible Network Management Card (NMC) 06 Redundancy & Reliability  The STS shall be designed for high reliability and high availability with an MTBF exceeding 2,000,000 hours. To the fullest extent practical, tri-redundant circuits with voting shall be used to eliminate single points of failure.  There shall be two levels of gate drivers on each set of SCRs. Each level cannot inhibit or out vote the other. Both the source 1 and source 2 shall have two levels of isolated, independent gate drivers. One gate driver can be replaced while under power (“Hot Swap”) without losing any performance.  There shall be triple redundant logic power supplies. The configuration of each DC logic power supply shall be such that a short circuit on one PCB cannot prevent the other PCBs from receiving triple redundant power. Each PCB shall receive logic power via three isolated connectors. The power supplies are mounted in separate modules so that one-power supply modules, including the transformers can be replaced while under power (“Hot Swap”) without any loss of performance. A. There shall be two levels of operator controls and status displays:  Graphical Touch Screen Interface  Back Up LED Interface If the normal graphic/touch screen display fails there is a redundant mimic panel and operator controls inside the unit. Each operator control/display PCBs can be replaced while under power (“Hot Swap”).
