Online UPS Benefits

Online UPS provides the highest level of power protection to the equipment/ machinery.  It offers an electrical firewall between the incoming utility power and sensitive equipment and completely isolates the output from all input anomalies through its double conversion design.  It features Fail-safe/overload protection with static bypass facility and wide input voltage tolerance. The online UPS System generates a new potential waveform independent of the input. This means that productivity voltage and frequency are flat and unchanging. Thus the UPS System delivers 100 per cent conditioned, Pure Sine Wave output, regulating both voltage and frequency. 

 It allows precise control of output voltage and frequency regardless of input voltage and frequency.  Distorted waveforms or variations in frequency are not blocked by some systems and feed these potential problems to your load. The pure sine waveform in an online UPS System ensures that your load is provided with clean power at all times.  Even if presented with the most severe power problems at Input like fluctuations, spikes, surges, harmonics and common-mode noise, power output remains stable. 

 It has scalable architecture and can be field-upgraded for capacity or redundancy.  The latest technologies in Online UPS provides improvement in ‘Input Power Factor’ and ‘Input Current waveform’, so less current is drawn – including reductions in high-frequency harmonics. By dynamically maintaining Power Factor close to unity results in the following benefits: 

(i) Energy waste minimized.

 (ii) Electricity bills reduced.

 (iii) Power Consumption reduced.

 (iv) High Operational efficiency.  

Online UPS provides a break-free power supply in the absence of electricity from the mains. In fact, they have a zero transition time as the only change is changing from rectifier fed DC potential to battery fed DC potential. This change is seamless and there are no noticeable or observable effects on the productivity load.  Online UPS features intelligent battery management which results in less battery usage, preserves battery capacity for extended outages and also preserves battery service life. Fewer machine breakdowns because of the improved voltage profile.  

The low maintenance cost of the equipment/ machinery.  It increases the life of the equipment/ machine considerably.  The total cost of ownership (TCO) of the equipment/ machine is also decreased because of lesser breakdowns in machinery/equipment. In summary, an online UPS System using double conversion technology provides the highest level of power protection available. Because the AC output is completely regenerated, it will be completely free from any mains-borne interference such as spikes and voltage variations. The output voltage and frequency are controlled precisely, thus ensuring a clean and stable sine wave power output. 

Online UPS are able to withstand large fluctuations on the input voltage before transferring to battery power (typically 276V-184V) thus eliminating unnecessary battery discharges. Upon mains failure, transfer to battery power is seamless – no break. Online UPS also have various fail-safe and self-diagnostic features that will instantly transfer the load onto mains power if there is a failure within the UPS hardware, or if the UPS is overloaded.
