UPS System for Medical Equipment

CT Scan UPS systems

Salient features

  • Very low input power requirement-15 kVA*
  • In-built galvanic isolation
  • Hyper dynamic response
  • Instanteeous sine correction
  • Input power factor correction

Benefits

  • Saving on power sanction and cabling cost
  • Saving on generator cost(lower capacity generator is required)
  • Saving on diesel cost
  • Reduced ct breakdowns and uninterrupted patient scan
  • Hyper dynamic response ensure voltage corrections within 5 to 8 milliseconds

* UPS can be programmed for desireable input power requirement irrespective of outpower capacity.

Conventional online ups

  • Power is drawn from mains during x-ray exposure
  • UPS works on battery mode only in the absence of mains
  • Low efficiency charger

 

CT online UPS

  • Power is drawn from mains only when console is operational.
  • During exposure power is drawn from battery.
  • Irrespective of o/p capacity of ups,i/p capacity can be programmed.
  • High efficiency ,high frequecy charger to facilitate on/off switching at the input.
  • No need for high capacity generator to run the machine.
