Custom design and manufacture of
state-of-the-art battery chargers, UPS, and power supplies for OEMs in a
hurry!
There are two types of inverters, modified sine wave and
pure sine wave. The most common is "modified sine wave," which is a square wave
with a pause as it passes through zero volts. This pause puts most of the power
in the fundamental frequency of 60Hz, but does not eliminate all the higher
harmonic frequencies which can cause buzzing in audio and entertainment
systems, and can cause probems in some sensitive equipment.
In the
modified sine wave inverter the power MOSFET switches are either all the way on
or all the way off. This means that there is very little power dissipated in
the MOSFETs. This enables the inverter designer to use much smaller transistors
and heat sinks than the pure sine wave inverter, and makes the modified sine
wave very cheap.
These inverters are pure sine wave inverters, which
means that the output is a sine wave, which only contains the fundamental at 60
Hz. Therefore it doesn't radiate or transmit noise to other equipment and is
kinder to the electronics that it is powering. It is a good, solid design, and
a great price for a pure sine inverter.
In other words it is just like
the clean power you have in your home or office.

Installation notes: To draw 300 watts from the inverter you
will need to supply about 27 amps at 12 volts of battery power for the input.
Plan for large wires. For wire
sizing information click here. For 1000 watts of peak power you will need
92 amps of 12 volt battery power. For the 24 volt models divide these currents
by two.

Advantages:
 Inexpensive true sine wave
inverter with relatively light weight for power supplied.
Protects battery from
overdischarge damage.
Alarm sounds some time
before it cuts out due to low battery. How long this is depends on your battery
capacity.
Low cost. Note: these inverters are off-the-shelf for retail and wholesale
orders. OEM quantities are available on a custom order basis |
