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.
FEATURES: * Primary / Secondary Isolation * Soft Start Operation
* Output Short Circuit Shutdown Protection * Input Polarity Reverse Protection * Battery High / Low Voltage Protection
SPECIFICATIONS: 120VAC 60 HZ (OR 220VAC 50 HZ) OUTPUTS: * 12V DC pr 24V DC Power Input * 120VAC 60 Hz (or 220VAC 50 Hz) Output
* True (Pure) Sine Wave * 300W Continuous / 1000W Peak Output *
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 |
