PS0500 Genset
controller
Cummins PowerStart™
PS0500 control is a microprocessor
based generator set monitoring and
control system. The control provides
a simple operator interface to the
generator set, manual and remote
start/ stop control, shutdown fault
indication, and an LCD hour counter.
The integration of all functions
into a single control system provides
enhanced reliability and performance
compared to conventional generator
set control systems. This control
has been designed and tested to
meet harsh environment in which
gensets are typically applied. |
