DSE7450 DC Generator Control Module

DSE7450 DC Generator Control Module


Project Description

The DSE 7450 is a control module designed to control DC generators in supplying both a load and/or the charging of batteries

Specific attention has been given to ensure this module has the necessary features to be configured for many different and challenging applications. Owing to the large number of monitoring points and the built in programmable logic controller, a wide number of operating modes can be realised. This provides the user with the ultimate flexibility in the engine control of the generator to ensure battery life optimisation, reduce engine maintenance/replacement and fuel usage.

Key Features Key Benefits
Automatic/manual start with configurable start/stop timers. Offers flexibility to control the module manually, remotely or on pre-set timers and start/stop according to battery condition.
Configurable inputs/outputs (10/8). Provides multiple installation options.
Mains (Utility) failure detection. Gives full mains (utility) back up.
AC/DC voltage measurement. Provides flexibility for use on AC or DC systems.
Battery temperature monitor/charge remaining display/depth of discharge display. Provides information on battery temperature, charge remaining and depth of discharge.
Backed-up real time clock. Ensures data is not lost when module is disconnected from its power source.
Configurable event log (250). Provides access to historical alarms and operational status.
Battery condition automatic start/stop. Avoids the battery draining completely by starting the generator when the battery needs charging.
USB, RS232, RS485, Ethernet and Modbus RTU/TCP communications. Provides secure and simple off site monitoring. All ports are continuously active.
