The DSE7510 is an Automatic Engine Control Module, designed to
provide advanced load share functionality for diesel and gas
generating sets that include electronic and non-electronic engines.
The module’s load share functions include automatic
synchronising with built-in synchroscope and closing onto dead
bus. Direct and flexible outputs from the module are provided to
allow connection to the most commonly used speed governors and
automatic voltage regulators (AVRs).
A sophisticated module monitoring an extensive number of
engine parameters, the DSE7510 will annunciate engine shutdowns,
warnings, and engine status information on the back-lit LCD screen,
by illuminated LED, on a remote PC, by audible alarm and via SMS
text alerts (GSM modem required). The module includes RS232 and
RS485 ports as well as dedicated terminals for system expansion.
