1. SPECIFICATIONS
1.1. APPLICATIONS
KT-PPC(Programmable Power Controller) optimizes the ship and ground power generation systems
and efficiently perform an active power management & control by controlling KT-ASD(Auto synchronizing
Device) and KT-PWC(Power Controller). Normally KT-PPC is designed to control 3 generators but you
can enlarge its capacity to maximum 5 generators with extension module.
AND self-diagnosis function lets you find out the cause of the errors in the case of problems, so it is
easy for you to maintain the power control system. You can build electric power control system for
various applications by modifying or changing the control program according to your system
configurations.
