Uninterruptible Power Supply (UPS)
 
 
 
  Helios - HE Online UPS Series - 5 KM to 200 KVA  
   
 
 
     An ONLINE UPS basic design ensures increased reliability by supplying constant, tightly regulated - voltage to the load.
 
 
 
     Helios offers an online, double conversion UPS system. Helios online UPS system is designed to handle wide input range voltage deviations without causing the battery system to take over the inverter load. This reduces the UPS systems reliance on its battery bank thereby increasing the life of the same.
 
 
 
     Introduction of IGBT - based PMW technology reduces harmonic distortions and increases crest factor tolerance and dynamic stability. IGBT based PMW inverter delivers full rated power at temperatures as high as 45 degree centigrade.
 
 
 
Constant current & constant Voltage technology ensures uniform charging of the battery
 
 
 
Flexibility to use various types of batteries like LAT (Lead Acid Tubular), LAP (Lead Acid Plante), SMF (Sealed Maintenance Free), Ni-cd (Nickel - Cadmium)
 
 
 
Standard communication Interface (Optional).
 
     
     
  Helios - XL Series - Upto 150 KVA
   
  Rectifier    
 
     Which converts AC voltage of the mains into DC voltage supply for the inverter and battery. Its adequate sizing allows the recharge of long array of batteries while simultaneously supplying the inverter. In order to avoid in rush current on mains, the electronic regulation assures a smooth power walk - in .
 
 
 
Battery
 
 
     Provides the energy for the back up in the event of a power failure or if the mains supply is out of tolerance " Sealed lead" battery technology is usually proposed, which uses gas recombination. This allows the integration of the battery in the UPS itself or in a matching cabinet and it limits the maintenance.
 
 
 
Inverter
 
 
     Which provides AC voltage of high quality to the load by transforming the DC voltage from the rectifier or battery. IGBT power transistor and PMW technology is used with high frequency switching. This gives it exceptional dynamic performance both for step loads and for supplying non-linear loads due to switch mode computer power supplies. The built-in transformer ensures the galvanic isolation bet'n DC voltage and the load.

 
 
Static BY PASS
     Which enables the load to be supplied directly by the mains, without interruption, in the event of excessive overload or breakdown of the UPS.
 
  Manual BY PASS
    To provide continuity of supply to the load during maintenance of the UPS.
