Relative humidity 0 to 95%, Online double conversion true sine wave
Uninterrupted hot swappable (allow for the replacement or addition of
battery modules without shutting down the entire system) modular Power
Supply (UPS) system with N+1 modules (N denotes total number of moduels
requird for rated capacity). The UPS shall include a Rectifier, inverter,
battery bank suitable for 30 minutes back up (Battery VAH capacity shall not
be less than 1600 VAH per KVA of UPS rating per Hour backup time) on full
load (Battery shall be VRLA, SMF in ABS Container) and Static Bypass
switch alongwith provision for manual bypass, suitable isolation transformer
for additional protection against neutral faults etc. UPS shall have inbuilt
phase sequence correction. The UPS systems offered are to be of the latest
technology with Digital Control Microprocessor based for reliable operation
using 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 International
standards such as IEC/EN/VDE. The operating efficiency of the
UPS systems shall be >96% while operating on battery mode and delivering
quality power to the 100% non-linear loads. Current total harmonic
effect(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) to
0.99 and output power factor shall be unity (i.e. kw rating of the UPS shall be
kva rating x 1 ), however UPS shall be suitable to take load at 0.7 laging to 0.7
leading 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 over
charging, output over current, short circuit protection, battery deep
discharge protection, 10KV surge. UPS must comply with low voltage
electromagnetic compatibility (EMC) achieved as per EN 6204, EN6204 Part
I and Part 2, it shall be a Voltage and Frequency Independent (VFI)-type
UPS. Communication RS232/RS485/SNMP port open protocol for BMS
integration, all hardware & software for iOT Communication as per approved
by Engineering in charge. Required battery racks and interconnecting
copper conductor cables of suitable size and connectors and all required
accoseries are inclusive of the cost). This system must provide a means for
logging and alarming of all monitored points plus email notification. Forced
air-cooling with integral inbuilt fans with redundancy (if one fan fail UPS
should be able to handle at least 80% of the load, Noise Level 65 DB at 1
meter distance. The system shall be in compliance IEC 62040- 1,2 & 3, IS:
16242 and CPWD Specification. Display Panel (minimum) (In-build 5 inch or
more 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 (On
LCD/LED): UPS should capture and display up to 3000 events like: Over
temperature / 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) Mains
Mode of Operation /Battery Mode of Operation / Bypass feeding the load /
UPS Fault /Battery charging and discharging, overload, battery voltage and
battery capacity. j) Audible Alarms : Mains Failure, Battery Low Alarm, UPS
Overload, Fault, Shutdown, Input Over, Under Voltage, Output Over, Under
Voltage, Battery Over, Under Voltage, Over Load and short circuit, Over
Temperature. The UPS should have QR code which should contain
drawing, test report OEM manual,Geo- Tag of manufacturing location etc. | | |
