Description
The AS3000 provides automatic start up, fault mon-
itoring and shutdown control for engine driven
applications. The unique two-module design, with a
single interconnecting lead, gives reduced panel
wiring and installation. This simple, compact unit is
ideally suited to small engine and generator panels.
