11. Generator option
11.9 Technical characteristics of
400/230V 8kVA KWG
generator
Generator model KWG-110/2-Z11-001
Generator type Synchronous, internal
pole, brushless with
exciter, electronically
controlled

Generator characteristics:
Extremely low dynamic internal resistance,
same output voltage whether hot or cold,
no dangerous overvoltage during dynamic
overspeed, small reactive effect from non-
linear or very inductive equipment, trouble-
free operation of equipment with phase
control, no dangerous overvoltage of the
unloaded phases, load current may have
significant DC components
