The EnerTech ETXi Series 3 Phase Input, 1 Phase Output (3:1) Online UPS is specifically designed for facilities where a three-phase utility supply is available, but the critical equipment operates on a single-phase power supply. Using advanced true online double-conversion technology, the UPS delivers clean, stable, and uninterrupted power with zero transfer time, ensuring maximum protection for your valuable equipment.
Available in capacities from 10kVA to 120kVA, EnerTech’s 3:1 Online UPS is ideal for commercial buildings, hospitals, laboratories, banks, IT infrastructure, manufacturing plants, telecom, and industrial automation.
1. SCR Based Online UPS:Â The EnerTech SCR Based Online UPS is engineered for industries where reliability, ruggedness, and long-term performance are critical. Built with Silicon Controlled Rectifier (SCR) technology, these UPS systems are ideal for handling heavy electrical loads, harsh operating conditions, and demanding industrial applications. SCR technology has been trusted for decades due to its robust design, excellent overload handling capability, and proven reliability. EnerTech SCR Based Online UPS provides uninterrupted power while protecting mission-critical equipment from voltage fluctuations, power outages, surges, and electrical disturbances.
2. IGBT Based Online UPS: The EnerTech IGBT Based Online UPS is designed using advanced Insulated Gate Bipolar Transistor (IGBT) technology to provide high efficiency, superior power quality, and intelligent digital control. Compared to conventional UPS systems, IGBT technology delivers lower harmonic distortion, improved energy efficiency, faster response, and a compact design. It is an excellent choice for modern businesses, data centers, hospitals, IT infrastructure, and commercial facilities.
3. PFC Based Online UPS :Â The EnerTech Power Factor Correction (PFC) Based Online UPS is designed to maximize energy efficiency while minimizing power losses. Active PFC technology ensures that the UPS draws power efficiently from the utility supply, resulting in a high input power factor and reduced harmonic distortion. PFC Based UPS systems help businesses lower electricity costs, improve power quality, and reduce the load on electrical infrastructure.
