GTR-168 is low cost but multi-function diesel engine generator controller. It applies a key switch and provides 3 kinds of operation mode: Manual, Auto, Off. No special training is required due to the easy operation. Fault protection includes: Emergency stop, Over speed, High water temperature, Low oil pressure, and Over crank.
GTR-168 also displays the low battery voltage warring, and indicates the running status and power status.GTR-168 equips with high firm continental-type terminal that provides easy plug in and removal.

Furthermore, GTR-168 has 10 pins Dip switch for adjusting parameter according to system requirements, and make it not only reducing stock but also meeting the various system specifications. GTR-168 build-in 5 output powers relays which perform high power capacity reach to 5 Amp (DC) that saves the wring for connection with extra power relays. No matter in function, protection or operation performance. GTR-168 is your best choice.
