Two UPS technologies dominate, ‘on-line’ and ‘off-line’. Almost all units described by their manufacturers as being ‘line interactive’ are off-line units but with the addition of an Automatic Voltage Regulation (AVR) transformer.
The description ‘on-line / off-line’ simply indicates whether the inverter (that part of the UPS that converts the DC provided by the batteries to the AC that we use from a wall socket) is on-line or off-line during normal use. Almost all UPS rated at 10kVA and over are on-line.
Lower cost than other units
Under mains power unit charges batteries and power passes directly to the load
During mains failure batteries provide power to DC/AC inverter to provide 230VAC power to the load
Square-wave or Sine-wave output
E.g.: Sukam Shiny, Fusion Falcon etc.
Constant duty inverter
Design inherently improves power quality and reliability
Static bypass improves reliability
E.g.: Sukam Trust MX, InelliQ etc.
LINE INTERACTIVE UPS
These UPS offer enhanced power protection over the basic off-line designs because they provide additional line conditioning. They can also cope with a wider range of input voltages without resorting to battery.
E.g.: Sukam “CONNECTO” 2.5 KVA Interactive UPS.
HIGH CAPACITY OFF-LINE UPS
powered with reliable, regulated and stabilized Pure Sine Wave Output is a complete power generation system that is suitable for all types of commercial establishments and is capable of running everything from Lights to Air Conditioners and Lifts to Elevators, in a most cost effective manner.
DSP Sine Wave Inverter supplies pure power, which is actually purer than even the power supplied by the grid, and is 100% safe to run the most sophisticated, expensive and sensitive office equipment, silently. It has already established itself as a most reliable option to generators at banks/ATM’s, hospitals, petrol pumps and shopping malls to name a few.
