Basler Electric DGC-2020 - Manual (Page 25)

SECTION 1
• GENERAL INFORMATION
Description
The DGC-2020 Digital Genset Controller provides integrated engine-genset control, protection, and
metering in a single package. Microprocessor based technology allows for exact measurement, setpoint
adjustment, and timing functions. Front panel controls and indicators enable quick and simple DGC-2020
operation. Basler Electric communication software (BESTCOMSPlus
®) allows units to be easily
customized for each application. Because of the low sensing burden in the DGC-2020, dedicated
potential transformers (PTs) are not required. A wide temperature-range liquid crystal display (LCD) with
backlighting can be viewed under a wide range of ambient light and temperature conditions.
