2.1.4 Product models and specifications

 

The  model  and  specifications  of  the  SV800  series  are  shown  in  below  Table  2-1.  The  input 
voltage  is  three-phase  three-wire  system  (400V±15%  50/60Hz±5%),  and  the  output  voltage 
varies with the input voltage; the output power P

N

 is valid at the rated voltage U

N

=380V.
