About the Deep Sea Electronics DSE7520

The DSE7520 is DSE's auto mains (utility) failure control module for paralleling a single generating set with the mains (utility) supply. DSE says it automatically starts the generator on a mains failure and controls the switchover from and back to the mains, offering an uninterrupted return; it synchronises with a built-in synchroscope and drives the governor and AVR. Its data sheet gives generator and mains (utility) ranges of 15 V to 333 V AC (L-N), 9 configurable inputs and 5 configurable outputs. Deep Sea Electronics lists the DSE7520 as obsolete and names the DSE8620 MKII as its replacement.

What is the DSE7520 used for?

The DSE7520 runs a single generating set that backs up or parallels the mains (utility) supply. It handles the change from mains to generator and the uninterrupted return to the mains.

Lifecycle and successor

Discontinued.

OEM successor: DSE8620 MKII
