Power Input
Operating power for the DGC-2020ES is typically supplied by the genset starter battery. Power from the
battery is supplied to an internal power supply that provides power for DGC-2020ES logic, protection, and
control functions.
Nominal Voltage Input and Acceptable Range of Input Voltage
A nominal voltage of 12 or 24 Vdc within a range of 6 to 32 Vdc is accepted. Operating power must be of
the correct polarity. Although reverse polarity will not cause damage, the DGC-2020ES will not operate.
Terminal Assignments
Input power is applied to terminals 18 (BATT+), 17 (BATT–), and 16 (CHASSIS).
Power Consumption
The amount of power consumed by the DGC-2020ES varies based on the selected mode. The power
saving Sleep mode consumes 4.5 W with all relays de-energized. The Normal Operational Mode
consumes 6.5 watts in Run mode with the LCD heater off and 3 relays energized. The Maximum
Operational Mode consumes 14 watts in Run mode with the LCD heater on and 7 relays energized.
Battery Ride-Through Capability
Starting at 10 Vdc, withstands cranking ride-through down to 0 Vdc for 50 milliseconds.
Fuse Protection
To follow UL guidelines, a 5 A maximum, 32 Vdc supplementary fuse must be implemented in the battery
input circuit to the DGC-2020ES.
