The PPT Series UPS has 3 level IGBT design to deliver improved efficiency from a considerably smaller and lighter design. PPT IGBT Series UPS can achieve efficiency up to 96% in Online Mode and 99% in eco mode
PPT Series UPS’s IGBT rectifier increase Input Power factor near to Unity and allows a reduction of total input current harmonic distortion (THDi) to less than 3%. This limits harmonic emissions and enhances the electromagnetic compatibility between the source and the equipment, the UPS feeds. Unity Power Factor output ensures any type of load connection without de-rating.
The User-friendly 7” touch-screen multilingual colour graphic display which enable the user to work upon every aspect of the UPS and set the conditions. The touch Screen also allows user to watch the 1200 events recorded on a first cum first basis.
The wide DC bus bar is a new development in PPT Series UPS which can be connected from 360 to 600 VDC. This feature helps the user to increase the DC back up for his load, adding from 30 to 50 batteries. This enables PPT Series UPS as best-in-class with maximum DC flexibility.
PPT IGBT Series UPS can be paralleled up to Six units ofrated capacity and it has Inter Power Walk in facility which enable the UPS to control the interval that each UPS transfers from battery mode to normal mode, which reduces the impact on the generator or power grid. The value can be settable from 0~200ms,default value is 10ms.
