DSE4520MKII Compact design, unleashing superior functionality and flexible control

Deep Sea Electronics proudly presents the Deep Sea Controller 4520MKII, a compact automatic power (AC) fault control module that combines high integration with outstanding functionality. This module not only functions as an automatic start controller, but its core advantage lies in its unparalleled flexibility. With the DSE4520MKII, customers only need to stock one universal model to meet diverse application needs, greatly optimizing inventory management and cost-effectiveness.

The DSE4520MKII offers complete monitoring flexibility, presented to users through clear and easy-to-read information pages. Its robust design ensures the display continues to operate normally in extremely cold weather conditions, while also possessing the ability to not lose data when the module is disconnected from the power supply, guaranteeing system stability and data security. The module provides true Generator and power (mains) sensing, delivering clear and accurate power measurement messages and realistic indications of the energy supplied by the generator.

Users will experience complete user-friendly configuration and easy-to-use advanced system control and monitoring.Minimize battery consumption to the greatest extent when the system is not in use.Provide overload protection for the engine and generator. It also effectively prevents damage to the alternator from unbalanced loads. Users can also choose to configure the module to display text instead of traditional icons, further enhancing operational intuitiveness. The module is suitable for various senders and temperatures and supports multiple installation options.

The practicality of the DSE4520MKII is also reflected in its rich additional functions, further expanding its application range. These features include: fuel solenoid valve traction circuit, fuel tank dam alarm digital input, backlit power-saving mode, screen line graph on/off function, alternator standby output, adjustable delay crank timer, AC/alternator air conditioning system selection, and an output timer for external audible alarms. 
Furthermore, it supports configurable CAN instrument cluster, periodic ECU wake-up for information retrieval, pre/afterheating functions, and fuel water level digital input. A single digital output can be used for the power transmitter, providing greater possibilities for system integration. These improvements, such as optimization for engine coolant temperature, including a pre-alarm for early warning, demonstrate the meticulous attention to detail in the DSE4520MKII.
