Description
The inverter converts 12 VDC voltage from battery or from other suitable 12 VDC source
to 115 V, 60 Hz AC voltage. The waveform of the of the AC output voltage is Modified
Sine Wave.

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 first 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.
• Similar overload reduction will be initiated during any other momentary overload
condition.
Low interference technology
Innovative circuit design and noise filtration circuitry reduces RF interference in TV
picture, 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 chassis
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 load-controlled
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.
