User manual SIMA STP-150

[. . . ] If you are not familiar with 12 volt, high-current wiring, it is recommended that you have a professional automotive installer install the inverter. Cautions · The STP-150 generates 115 Volts AC power from your 12 volt car battery. Treat the 115 Volt AC output just like you treat the 115 Volt AC in your house. Do not allow water to drip or splash on the STP-150 Keep the unit in cool environments. Keep the unit away from flammable material or in any location which may accumulate flammable fumes or gases, such as the battery compartment of your car, boat, RV or truck. · · · Sima Products Corporation 140 Pennsylvania Avenue Bldg. [. . . ] The power source must be able to provide sufficient current to power the load. The STP-150 comes with a cigarette lighter plug for easy connection to the power source. Insert the plug into a cigarette socket by pushing firmly for a good connection. Testing the Power Inverter Make sure the 12 volt power source is wired properly to the power inverter. With nothing plugged into the 115 VAC outlets, turn on the power switch of the STP-150. If the green power light does not come on, turn the power switch off and check your wiring and external fuse. With the inverter turned off, plug the appliance you want to use into the 115 VAC power outlet on the unit. The appliance should now be operational. Important: The STP-150 can draw up to 15 amps from your car's battery when operating. If you are using it for extended periods of time, you will want to operate your car occasionally to maintain the charge in your car's battery. The STP-150 will also draw a small current when not operating, so it should be disconnected from your car's battery if your vehicle will not be used for a few days. Lights and Alarms Power Indicator (Green light) The green light is illuminated when the inverter is turned on and is operating normally. If this light goes out, either the 12 volt power supply is missing (possible blown fuse) or some fault condition has occurred. These fault conditions include: output overload, output short circuit, low input voltage and over-temperature of the unit. This can happen if a device has a large start-up surge, if an appliance (like a drill or saw) is stalled or if the inverter does not have a circulating supply of cool air. Overload Fault (Red light) The red light is illuminated when a current overload fault is detected. An overload fault occurs when the power draw exceeds the inverter's maximum capability. An under-voltage fault (beep) An under-voltage fault can occur when the input voltage reaches about 10. 2 volts. The STP-150 will sound a continuous alarm and shut off when the input voltage drops to 9. 6v to protect your battery from being completely discharged. An over-temperature fault An over-temperature fault occurs when the STP-150 internal circuitry gets too hot due to overload or improper air circulation. The STP-150 will turn off the green power light and the unit will turn off. Fuse Replacement (see figure 2) If you overload the STP-150, it is possible that the fuse in the cigarette plug might blow. If this happens, unplug the cigarette plug from the power source, wait for the tip to cool and unscrew the metal tip on the plug. Always determine why the fuse blew and remedy the problem before using the STP-150 again. Operation Equipment Power Usage It is important to use only products that draw less than 150 watts with the STP-150. Use of products greater than 150 watts may either cause the protection circuitry of the STP-150 to shut down or the fuse to blow. [. . . ] Check that the battery and the 12V wiring to the inverter is large enough to handle the current draw. You may need to turn the power switch on and off a few times to get the appliance "started". Some motors and televisions may require this technique to get them operational. · Television and stereo interference. · 115 VAC Output voltage reads incorrectly. · RF interference from power inverter Typical Power Usage Chart Typical Appliance Cellular phone charger Camcorder VCR Soldering iron Laptop computer 13" TV 100 watt work light Small stereo system Typical Appliance Current Draw 20 watts 23 watts 40 watts 45 watts 75 watts 80 watts 100 watts 150 watts · Modified sine wave output can cause an incorrect reading on a typical multimeter.
