DSE7420

DSE7420 Auto Mains Failure Module

Features

The DSE7420 is an Auto Mains (Utility) Failure Control Module suitable for a wide variety of single, diesel or gas, gen-set applications.  A sophisticated module monitoring an extensive number of engine parameters, the DSE74xx will annunciate warnings, shutdown and engine status information on the back-lit LCD screen, illuminated LED, remote PC, audible alarm and via SMS text alerts. The module includes RS232, RS485 & Ethernet ports as well as dedicated terminals for system expansion.

 

The DSE7400 Series Modules are compatible with electronic (CAN) and non-electronic (magnetic pickup/alternator sensing) engines and offers a comprehensive number of flexible inputs, outputs and
extensive engine protections so the system can be easily adapted to meet the most demanding industry
paralleling requirements.

The modules can be easily configured using the DSE Configuration Suite Software.Selected front panel editing is also available.
