Description

The DSE8620 is an Auto Mains (Utility) Failure Control Module suitable for paralleling single gensets (diesel or gas) with the mains (utility) supply. The module will automatically start the generator on
detection of a mains failure, and will control the switchover from and back to the mains (utility) supply,offering an uninterrupted return.
The modules synchronising 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 DSE8620 will annunciate warnings, shutdown and engine status information on the back-lit LCD screen, illuminated
LED, remote PC, audible alarm and via SMS text alerts. The module includes RS232 and RS485 ports as well as dedicated terminals for system expansion.
