DC/Hybrid Generator Control Modules

DSE7450

DC/Hybrid Generator Control Module

The DSE 7450 is a control module designed to control DC/Hybrid 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.
