| 1 | Supply, installation, testing, and commissioning of a 10 kVA Online UPS system with three-phase input and single-phase output, based on double conversion (AC–DC–AC) topology, having a 192V DC bus. The UPS shall operate with an input voltage of 415V and frequency range of 40–70 Hz, maintaining an input power factor of ≥0.99. The output shall provide 220/230/240 VAC, with synchronized frequency in mains mode and 50 Hz ±0.1 Hz in battery mode, delivering a pure sine wave with unity output power factor, crest factor of 3:1, and THD of ≤3% (linear load) and ≤5% (non-linear load). The system shall include an inbuilt galvanic isolation transformer at output, with minimum 90% efficiency at full load.The UPS shall be equipped with comprehensive protections including overload, short circuit, over/under voltage, over temperature, surge protection, and static bypass, along with LCD/LED display, audible alarms, and communication interfaces such as RS-232/USB with optional SNMP. The system shall comply with IEC 62040 / IS 16242 standards, with BIS/CE/IEC certification, and be supplied with a minimum 3-year onsite warranty. | Supply, installation, testing, and commissioning of a 10 kVA Online UPS system with three-phase input and single-phase output, based on double conversion (AC–DC–AC) topology, having a 192V DC bus.
