Power Inverter Output Waveform - DeWalt DXAEPI1000 Manual De Instrucciones

Your product could be damaged by this inverter if it contains:
• Microwave ovens;
• Transformerless battery chargers
• Capacitive coupled power supplies
If an incompatible product is used with this inverter:
• The product might not operate at all, with no indication of failure. The
product fuse might open as a result of trying to use it with the inverter.
• The product might exhibit unusual operation (such as, intermittent
operation, buzzing, and the like.)
NOTES:
A. Some laptop computers may not operate with this inverter.
B. Some USB-powered household electronics will not operate
with these USB Ports. Check the manual of the corresponding
electronic device to confirm that it can be used with this type of
USB Port.
WARNING: If the product does not operate normally, to
reduce the risk of injury or property damage, turn the product
off immediately and unplug it from the inverter.
CAUTION – To reduce the risk of injury: Do NOT touch the metal
part of the DC plug after use as its surface may be quite hot after
extensive operation.

How This Inverter Works
G H
This inverter is an electronic device that converts low voltage DC (direct
current) electricity from a battery to 120 volts AC (alternating current)
household power. It converts power in two stages. The first stage is
a DC-to-DC conversion process that raises the low voltage DC at the
inverter input to 145 volts DC. The second stage is a MOSFET bridge
stage that converts the high voltage DC into 120 volts, 60 Hz AC.

Power Inverter Output Waveform

F
The AC output waveform of this inverter is known as a modified sine
wave. It is a stepped waveform that has characteristics similar to the
I
J
sine wave shape of utility power. This type of waveform is suitable for
K
L most AC loads, including linear and switching power supplies used in
M
electronic equipment, transformers, and small motors.
N
Rated Versus Actual Current Draw of
Equipment
Most electrical tools, appliances, electronic devices and audio/visual
equipment have labels that indicate the power consumption in amps or
O
watts. Be sure that the power consumption of the item to be operated
P is below 1000 watts. If the power consumption is rated in amps AC,
simply multiply by the AC volts (120) to determine the wattage.
Resistive loads are the easiest for the inverter to run; however, it will
not run larger resistive loads (such as electric stoves and heaters),
which require far more wattage than the inverter can deliver. Inductive
loads (such as TVs and stereos) require more current to operate than
do resistive loads of the same wattage rating.
