Soft Start Technology
This feature offers the following advantages:
• WhentheinverterisswitchedON,thevoltagerampsupto115VACinaround2sec.
If the load was already ON at the time of switching ON of the inverter, starting surge
current demanded by certain reactive devices like motors etc. will be reduced and
there will be less likelihood of the inverter shutting down due to overload.
• IftheinverterisswitchedONrstandthenaloadwithhigherstarting/inrush
current like SMPS / motor is switched ON, the voltage will dip momentarily and will
ramp up and reduce inrush / starting surge current in the load as above

condition
Low Interference Technology
Innovative circuit design and noise ltration circuitry reduces RF interference in TV pic-
ture, audio and radio equipment
Cool Surface Technology
Normally, heat dissipating components are mounted directly on internal metal chassis
surface of the inverter and hence, the chassis surface may rise to unsafe touch-tempera-
ture. In this inverter, heat-dissipating components are not mounted directly on the chas-
sis of the unit but on PCB (Printed Circuit Board) mounted heat sink and, there is air gap
between the heat sink and the chassis surface. The heat sink is cooled by fan. As there
is no direct contact between the heat sink and the chassis, the chassis surface remains
much cooler and is safer to touch.

Cooling Fan
A fan has been provided for cooling. It runs all the time.
PRINCIPLE OF OPERATION
Conversion of 12 VDC from the battery / other DC source to 115 VAC takes place in 2
stages. In the rst stage, the 12 VDC is converted to high voltage DC (around 160 VDC)
using high frequency switching and Pulse Width Modulation (PWM) technique. In the
2nd stage, the 160V high voltage DC is converted to 115V, 60 Hz Modied Sine Wave
AC. (Note: 115 V is the RMS value of the Modied Sine Wave AC voltage. The peak
value of the Modied Sine Wave AC voltage will be equal to the value of the above
high voltage of around 160V. See the Fig 2.1 below).
Modied Sine Waveform -
Charateristics & Comparison with Pure Sine Waveform
Please refer to Fig 2.1 below which shows one cycle of Modied Sine Wave and Pure
Sine Wave for comparison.
Fig 2.1 Modied Sine Wave and Pure Sine Wave - Comparison
The output waveform of the inverter is a Modied Sine Wave. In a Modied Sine Wave,
the voltage waveform consists of rectangular pulses that approximate sine wave pulses
of a Pure Sine Wave. The voltage rises and falls abruptly at a particular phase angle
and sits at 0 Volts for some time before changing its polarity. In a Pure Sine Wave, the
voltage rises and falls smoothly with respect to phase angle and the voltage changes its
polarity instantly when it crosses 0 Volts.

Measuring Modied Sine-Wave Voltage with a “True RMS” Voltmeter
As mentioned above, Modied Sine Wave voltage is a type of square wave that has an
RMS (Root Mean Square) value of 115 VAC in this inverter. A general-purpose AC voltme-
ter is calibrated to accurately measure the RMS value of a Pure Sine Wave and NOT of a
Modied Sine Wave. If this general-purpose voltmeter is used to measure Modied Sine
Wavevoltage,itwillindicatealowervalue(96VACto104VAC).Foraccuratelymeasuring
the voltage of a Modied Sine Wave, use a voltmeter which is designed to measure “True
RMSValues”likeFluke87,Fluke8060A,Fluke77/99,Beckman4410etc.

USB3.0,TypeA:5V,2.1A.
The vehicle’s 12V Power Outlet must provide between 10.8 and 15.4 VDC. To obtain a
rough estimate of the current (in Amperes) drawn from the battery, divide the power
consumption of the load (in Watts AC) by 10.
Example: lf a load is rated at 80 watts AC, the current drawn from 12V battery will be
80W divided by 10 = 8 Amperes.
Testing is the only denitive way to determine whether a specic load can be started
and how long it can run. The unit will shut down if it is overloaded.
!CAUTIONS!
1. Check the maximum supply current of your vehicle’s 12V Power Outlet by referring
to your vehicle’s owner manual.
2. The unit must be connected only to batteries with a nominal output voltage of
12 volts. The unit will not operate from a 6 volt battery, and will sustain permanent
damage if connected to a 24 volt battery.
3. DO NOT use with Positive Ground electrical systems. (The majority of modern auto-
mobiles, RVs, and trucks are Negative Ground).

NOTE: When the inverter shuts down due to activation of protection, the GREEN Status
LED (#4, Fig 2.1) will switch OFF.
1. OVER TEMPERATURE PROTECTION – If the temperature inside the unit is too high,
the unit will automatically shut down. Allow the unit to cool for at least 30 minutes
