Dalton UPS ES33 Series

Dalton UPS ES33 Series

Dalton ES33 Online Double Conversion UPS 
With Isolation Transformer
160kVA – 500kVA

The large capacities of ES33-Frindly Uninterruptible power supply is 
a combination of Dalton’s advanced digital signal processor ( DSP) control 
technology and a firm pursuit of a green manufacturing philosophy.
With minimum space, fewer components and controlled levels of noise pollution. 
The ES33 Series has a significantly reduced environmental impact. 
Therefore, it is feasible to design a UPS with reduced carbon footprint whilst 
achieving clean, continuous power for heavy medical,industrial and computing loads. 
– Output Factor 0.9
– Online double conversion & Input IGBT Rectifier
– 3 phases UPS allow 100% unbalance load
– IGBT inverter and output isolation transformer
– Fully DSP control, high reliability and performance
– Dual input supplies
