Power requirements
The singlephase DEWALT generators are designed for the operation of
singlephase 50 Hz electric devices for 230 VAC.
The threephase generators are designed for the operation of single-phase 50 Hz
electric devices for 230 VAC and/or triple-phase 50 Hz electric devices for 400
VAC. The single-phase or triplephase sides can be used at the same time.
NOTE
: Do not exceed the performance limit of the generator, as this may lead to
damage of the generator or the tools. See Technical Data.
Check the nameplates or labels of the tools and electric equipment to be connected
to ensure that the current values conform with those of the generator. Always
inquire with the manufacturer if equipment is lacking the wattage.
Some electrical equipment requires more power to start than to operate. The
generator must be able to provide this power. Some equipment actually requires
more current than specified on the nameplate.
The "General power requirements for starting" information only applies as a
general guideline to assist you in determining the power requirements. The nearest
DEWALT dealer, tool manufacturer can help you if you have questions.
NOTE
: Do not exceed the specified current limit at any plug receptacle.
NOTE
: If a tool or electrical equipment should not reach the full RPM a few seconds
after starting, switch it off immediately in order to prevent damage.
General power requirements for starting
White light bulbs and electronic goods, such as irons and hot plates, use a
resistor heating element and require the same amount of power during
startup that is listed on the nameplate.
When starting, neon and mercury lamps require 1.2-2 times the specified
wattage.
Many electric motors and power tools use a large amount of power when
starting. The electrical supply required during start-up depends on the type
of motor and the intended application.
When starting, most power tools require 1.2-3 times the specified wattage.
Connection units, such as submersible pumps and air compressors, require
a large amount of power when starting, even up to 3-5 times the specified
wattage.
If the wattage of a tool or electrical equipment is not specified, this can be
calculated by multiplying the voltage requirements with the amperage
requirements.
Single-phase: VOLTS x AMPS = WATTS
Three-phase: VOLTS x AMPS x 1.732 x 0.8 = WATTS
