UTL ALFA online UPS is an uninterruptible power supply incorporating Double-Conversion Technology. The double conversion principle eliminates all power disturbances in the main supply. ALFA online UPS provides an independent, no break source of clean, stable, transient free uninterrupted power supply with output neutral bonded to the ground this protects critical loads against power line disturbances and loss of commercial power. The UPS gives an accurately controlled sine wave AC output without any line disturbances. It provides Regulated Sinusoidal Output Voltage under several Input conditions such as power failure, surge, sag, spikes, noise, frequency instability and harmonic distortions. The true advantage of the ALFA online UPS is its ability to provide an electrical firewall between the incoming utility power and your sensitive electronic equipments. Highly reliable single Card based UTL’s Online UPS comprises of a rectifier, an auto float cum boost charger, battery backed inverter with under voltage, over voltage, short-circuit protection along with a high degree of Input to Output isolation. The amplification stage has IGBT technology for pure sine wave output. UTL’s ALFA online UPS is a Microcontroller, High Frequency PWM Technology Based “True Online” Double Conversion UPS System with IGBTs or MOSFETs at the Inverter Stage thus provides pure Sine wave output with high reliability and Efficiency. Making the ALFA online UPS totally fit for running heavy loads like ACs, Industrial Motors and Pumps at gas stations etc. Even highly sensitive medical equipments such as life support systems work flawlessly with this ups.
