ALPHATRAN™ Inverter System - LETHIEN TELECOM Company

Data SheetJanuary 2005ALPHATRAN Inverter System3.5 kVA - 21 kVA Scalable N+1 InverterSystem Overview and ComponentsSystem OperationThe Inverter plantreceives 48 VDCfrom a DC powerplant of batterybank and convertsthe output toprecision regulatedAC power (userselectable voltageand frequency). Inthe event that theDC is not availableor out of tolerancedue to a dischargedbattery, or theinverters are notAC Distribution PanelMaintenanceBypass CabinetRedundantMicrocontrollersInverterInverterStatic Bypass SwitchInverterInverterable to maintain the critical load, the system willautomatically transfer to the static transfer switchand disconnect from the DC source. The statictransfer switch (standard) will make a seamlessly,uninterrupted transfer from the critical load to analternate AC power source where the inverterpower was synchronized to (utility power oranother protected AC source). The availability ofthe Alphatran N+1 on-line mode with a backupsource present is greater than 99.9999%.AC Distribution PanelThe AC distribution panel accommodates 20 (7KVA system) or 24 (14 and 21 KVA systems) singlepole circuit breaker positions and is available in120 and 240 Vac versions. Note: all recommendedbreakers include distribution alarm monitoringcontacts that take up an additional pole position.This limits the maximum number of circuit breakersif distribution alarm monitoring is to be used. Themaximum number of circuit breakers that can beinstalled, with and without the additional alarmmonitoring contact, is shown below.Maintenance Bypass CabinetSafely and seamless transfers the output toan alternate AC source (utility power orprotected AC power from another inverter orUPS system) allowing the inverter to be shutdown or removed without interrupting powerto the critical loads. The maintenance bypassassembly is factory wired to the invertermodule when ordered as a system.Dual Independent MicrocontrollerModulesIf the primary microcontroller module is evercompromised the secondary modulecontinues to provide uninterruptedperformance.Redundant 3.5 kVA “Hot Swappable” InverterModulesPermits power modules to go off line and bequickly replaced while keeping the load oninverter power.Integrated Electronic Static Transfer SwitchProvides six sigma reliability by rapidlytransferring the load to an alternate AC powersource if DC power to the inverters is not available.Rack Mount Receiver Cabinet with RapidChange Connector SystemSwap components on-line safely and rapidly withno wiring connections and without risking systemperformance.Telecom Grade FilteringThe Alphatran is equipped with a high grade noisefilter system limiting ripple current on the battery towell under required levels, as well as ensuring thatradiated and conducted EMI are kept to safelevels.With Alarm ContactsSystem Single-Pole Double-Pole Single-Pole Double-Pole7 KVA 20 10 10 614 / 21 KVA 24 12 12 8Maximum Number of Circuit Breakers per AC Panel2 Tyco Electronics Power Systems, Inc.

Accessories include environmentalmonitoring modules and auxiliary inputs to monitorother devices such as leak detection system, roomsecurity or any other dry contact status points.Built to Meet Industry StandardsThe Alphatran inverter is designed to meet thestringent regulatory qualifications demanded bytelecommunications facilities. As well as meetingall major safety standards (including CE and UL),it is one of the only inverters designed to meetNetwork Equipment Building System (NEBS)standards - the industry benchmark for productquality and reliability.UL is a registered trademark of UnderwritersLaboratories, Inc.System Block DiagramACBypass InputMaintenance BypassDC InputAC DistributionPanelInverter Modules(1 - 6 Modules)3.5 kVA Inverter3.5 kVA Inverter3.5 kVA Inverter3.5 kVA Inverter3.5 kVA InverterStatic TransferSwitchEMI FilterStatic Transfer Switch AssemblyDry Contact AlarmsRS-232 Comm.
