Dalton UPS ES33 Series (10-120)

Dalton UPS ES33 Series (10-120)

Dalton ES33 Online Double Conversion UPS 
Three Phase Input & Output With Isolation Transformer

10kVA – 120kVA
The 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 medical,industrial and computing loads. 
– Output power factor 0.9
– Online double conversion
– 3 phases UPS allow 100% unbalance load
– IGBT inverter and output isolation transformer
– Fully DSP control, high reliability and performance
– Dual input supplies
