- IG 200 control system
IG200 genset paralleling controller is used for manual/automatic paralleling system of multiple generator sets of the same
capacity or different capacity, as well as suitable for constant power output and mains grid connection of a single generator
set, so as to realize the automatic start-up and shutdown/parallel operation, data measurement, alarm protection and “three
remote” functions of the generator set. The controller adopts a large-screen liquid crystal (LCD) graphic display, which can
display Chinese, English and other languages, which is simple to operate and reliable to operate.
