Sima 1500 Watt Titanium STP-1500 Manuel D’Utilisation

The Sima Products Corporation power inverter has two electronic sections.  The first section converts 
12 volts DC to approximately 160 volts DC using modern high frequency conversion techniques that 
uses small lightweight efficient transformers.  The second section converts the 160 volts DC to 115 
VAC using high efficiency power MOSFET transistor devices.  The inverters generate a modified sine 
wave that works with almost every product on the market. 
 

CAUTION:  Do not use the following products with an inverter with a modified sine 
wave output. 

 Small battery operated devices like razors, flashlights and night lights that can be 

plugged directly into an AC outlet to recharge 

 A few battery chargers for power tool battery packs that have warnings about high 

voltage present on the battery terminals. 

 

The Smooth Start feature of the STP line of power inverters is designed to handle the power surge that 
is created when some appliances are turned on. This feature helps protect both the appliance and the 
inverter from excessive power draws and surges. 
 
When the power switch is turned on, the STP inverter smoothly brings up the AC power. This circuitry 
also activates under excessive loads, even short circuits, to quickly turn off power to protect the device 
and the inverter. The STP inverter then attempts to smoothly bring up the AC power, unless it detects 
an excessive load.
