Siret Online UPS systems are used in mission critical applications such as for medical equipments – MRI / CT Scan etc, for large networks and for industrial applications such as CNC machines.
Digital Technology
Online UPS
Microprocessor based digital control ensures pure and perfect Sine Wave output delivering accurate voltage and clean power. It increases speed and efficiency of power conversion and facilitates communication interface between the machine and the user.
Double Conversion Topology
With Galvanic Isolation
This UPS topology provides complete isolation from the incoming distribution system and the load at the UPS output. Continuous protection of load is provided from the Inverter, whether it originates from AC-input supply or the battery. Wide input voltage tolerances, precise regulation of the output voltage and frequency and a no-break transfer to bypass mode are the other main benefits with double conversion
Active Power Factor Correction
APFC
The advanced technology used in the rectifier section with active power factor correction reduces power consumption by 30%. It reduces input current as well as voltage harmonics and helps to considerably downsize the generator or utility power rating. It has a soft-start feature to avoid inrush current.
Features of Power Factor Correction Technology
Online UPS
- Input power factor is improver to 0.9 in single phase and 0.93 in three phase machines.
- Power consumption will be lesser than conventional online UPS.
- The conventional phase angle control technology is the reason for more power consumption which is fully avoided.
- Wide input frequency 45-55Hz
- Soft start provided.
- Fail proof battery management system.
