| 1 | Online UPS- Input supply: Three Phase, Output supply: Three PhaseSupplying, installation, Testing & Commissioning of of following capacity atfull load (Unity Power Factor) at operating temperature 0 to 40 deg C,Relative humidity 0 to 95%, Online double conversion true sine waveUninterrupted hot swappable (allow for the replacement or addition ofbattery modules without shutting down the entire system) modular PowerSupply (UPS) system with N+1 modules (N denotes total number of moduelsrequird for rated capacity). The UPS shall include a Rectifier, inverter,battery bank suitable for 30 minutes back up (Battery VAH capacity shall notbe less than 1600 VAH per KVA of UPS rating per Hour backup time) on fullload (Battery shall be VRLA, SMF in ABS Container) and Static Bypassswitch alongwith provision for manual bypass, suitable isolation transformerfor additional protection against neutral faults etc. UPS shall have inbuiltphase sequence correction. The UPS systems offered are to be of the latesttechnology with Digital Control Microprocessor based for reliable operationusing Insulated Gate Bipolar Transistor (IGBT)'s both for the rectifier &inverter (3 Level) with PWM (Pulse Width Modulation). The quality of design,manufacturing and inspection process should confirm to the relevant Internationalstandards such as IEC/EN/VDE. The operating efficiency of theUPS systems shall be >96% while operating on battery mode and deliveringquality power to the 100% non-linear loads. Current total harmoniceffect(ITHD) on the input grid shall be < 5% at 50 %load. (The required LC (inductor (L) and a capacitor (C)) filters shall be included in UPS cost),extreme power factor kit to be included to limit the input power factor (PF) to0.99 and output power factor shall be unity (i.e. kw rating of the UPS shall bekva rating x 1 ), however UPS shall be suitable to take load at 0.7 laging to 0.7leading power factor loads. UPS shall be suitable for incoming supply AC :3Phase 400V +/-20%, 50 Hz +/-5 Hz, AC Output voltage: 3Phase 415 Volt,50 Hz +/- 0.2Hz, Overload capacity of 120% for 10 mins, Sine wave output.Non condensing, noise level less than 60db at 1 meter distance, protections:Input Under voltage over voltage, abnormal out voltage, battery overcharging, output over current, short circuit protection, battery deepdischarge protection, 10KV surge. UPS must comply with low voltageelectromagnetic compatibility (EMC) achieved as per EN 6204, EN6204 PartI and Part 2, it shall be a Voltage and Frequency Independent (VFI)-typeUPS. Communication RS232/RS485/SNMP port open protocol for BMSintegration, all hardware & software for iOT Communication as per approvedby Engineering in charge. Required battery racks and interconnectingcopper conductor cables of suitable size and connectors and all requiredaccoseries are inclusive of the cost). This system must provide a means forlogging and alarming of all monitored points plus email notification. Forcedair-cooling with integral inbuilt fans with redundancy (if one fan fail UPSshould be able to handle at least 80% of the load, Noise Level 65 DB at 1meter distance. The system shall be in compliance IEC 62040- 1,2 & 3, IS:16242 and CPWD Specification. Display Panel (minimum) (In-build 5 inch ormore LC Display / LED ) to display : a) Input: Voltage, current, Frequency. b)Bypass: Voltage, Frequency. c) Output: Voltage, frequency, Current.d) Battery: Voltage, Capacity. e) Load: KVA, KW, Percentage.f)Temperature: STS, Inverter, PFC. g) Event Logging & Statistical Data (OnLCD/LED): UPS should capture and display up to 3000 events like: Overtemperature / DC Bus Fail / Fan Fail / Fuse Fail / Overload / Short-circuit /Device Fail / Inverter Fail / Rectifier Fail / Bypass Fail, etc. h) Statistical Data:No. of power failures / Transfers to Bypass / Total Running time, etc. i) MainsMode of Operation /Battery Mode of Operation / Bypass feeding the load /UPS Fault /Battery charging and discharging, overload, battery voltage andbattery capacity. j) Audible Alarms : Mains Failure, Battery Low Alarm, UPSOverload, Fault, Shutdown, Input Over, Under Voltage, Output Over, UnderVoltage, Battery Over, Under Voltage, Over Load and short circuit, OverTemperature.
