Deep Sea DSE7320 Auto Mains Failure Module
The DSE7320 is an auto mains failure control module for a single generating set. It monitors the utility supply, starts the set on failure, transfers load, returns it when mains is restored, and provides engine and alternator protection with event logging. It is configured over USB with DSE Configuration Suite.

Questions about this part
Does a replacement DSE7320 need configuring?
Yes. A replacement ships with factory defaults. Timers, CT ratio, protection thresholds and input and output functions must be set for the installation, ideally by loading the configuration file from the original module.
What speed sensing does the DSE7320 need?
It accepts a magnetic pickup, a charge alternator W terminal, or alternator frequency. Magnetic pickup is preferred where accurate crank disconnect and overspeed protection matter.
