DSE720

Auto Mains (Utility) Failure Control Module

Features

The DSE720 is an Automatic Mains (Utility) Failure Control Module suitable for a wide variety of single diesel or gas genset applications.

Monitoring an advanced list of engine parameters, the DSE720 will automatically shut down the engine, or indicate a warning, on detection of a fault condition, indicating the fault on the module’s front panel LCD display or LED.

The module can be easly configured using the DSE810 interface and PC. Front panel editing is also available.

The module can be controlled from a PC that is located up to a maximum distance of 100 meters
away.

The DSE720 also has the ability to monitor the mains (utility) supply, automatically controlling the
switch-over to generator when the mains (utility) power fails.
