Controller Brand & Model: Deepsea DSE6120

The DSE6120 is an Auto Start & Auto Mains (Utility) Failure Control Module suitable for a wide variety of single, diesel or gas, gen-set applications. It monitors speed, frequency, voltage, current, oil pressure, coolant temperature and fuel level, and the modules will display warnings, shutdown and engine status information on the back-lit LCD screen and illuminated LED.

The controller offers electronic (CAN) and non-electronic (magnetic pick-up/alternator sensing) engine versions and offer a number of flexible inputs, outputs and engine protections so the system can be easily adapted to suit a wide range of application demands.

The controller can also be easily configured using the DSE Configuration Suite PC software. Selected front panel editing is also available.
