DSE4520 MKII
AUTO MAINS FAILURE CONTROL MODULE
The DSE4520 MKII Auto Mains (Utility) 
Failure Control Module is suitable 
for a wide variety of single gen-set 
applications. 
Whilst maintaining functions included 
within higher end controllers, such as 
generator and load power monitoring, 
the DSE4520 MKII provides the user 
with an outstanding size to feature 
ratio.
Monitoring engine speed, oil pressure, 
coolant temperature, frequency, 
voltage, current, power and fuel level, 
the modules will give comprehensive 
engine and alternator protection. This 
will be indicated on the largest back-lit 
LCD icon display in its class via an 
array of warning, electrical trip and 
shutdown alarms.
The module provides electronic J1939 
(CAN) and non-electronic (alternator 
frequency sensing) engine support for 
diesel, gas and petrol engines all in 
one variant. With a number of exible 
inputs, outputs and protections, the 
module can be easily adapted to suit 
a wide range of applications.
Through USB communication the 
module can be easily congured 
using the DSE Conguration Suite PC 
Software or can be fully congured 
through the module’s front panel 
editor.
All DSE products are supported by 
our dedicated technical support team, 
which gives customers and end users 
access to 24 hour help and advice.
