Deep Sea Electronics DSE7420 MKII Auto Mains Failure Control Module – DSE7420 Series
When mains power fails unexpectedly on an industrial site, every second without a functioning generator control system can mean halted production lines, compromised safety systems, and costly downtime. Without a reliable Auto Mains Failure (AMF) controller, a generator set cannot automatically detect the utility failure, start the engine, and transfer the load — leaving critical infrastructure exposed. The Deep Sea Electronics DSE7420 MKII eliminates this vulnerability by providing fully automatic, intelligent mains monitoring and generator control in a single, field-proven module.
Within the DSE7420 Series, the MKII revision represents Deep Sea Electronics’ refined second-generation AMF controller — incorporating enhanced measurement accuracy, expanded communication options, and improved EMC compliance over its predecessor. DSE is a globally recognized leader in generator control technology, with its modules deployed across power plants, data centers, hospitals, and industrial facilities in over 150 countries. The DSE7420 MKII is a benchmark product in the mid-range AMF controller segment, trusted by OEM generator manufacturers and end-users alike.
