A voltage converter that does all the work for you. The converter detects the wattage of your appliances for you, and switches itself accordingly from a 0-50 watt transformer to a 51-1875 watt converter. For use with battery chargers, curling irons, shavers, toothbrushes, and other electronic or electric appliances between 0-50 watts, and for use with hair dryers, clothes steamers, irons, heating pads, coffee makers, beverage heaters, and other electric appliances between 51-1875 watts. You cannot use a voltage converter without an adapter plug! Even though the voltage converters have 2 rounded pins (as used in most of Europe) the outlets are recessed and an adapter plug is still necessary. If your appliance is dual or multi voltage, you do not need a voltage converter, only an adapter plug. Available in individual or as a set.

Transformers Movie 2 Combiner - Construction Devastator
List Price: $109.99
Sale Price: $299.99

One of the biggest Transformers toys ever made, the Constructicon Devastator brings the power of the Decepticons to your home. Having appeared in the summer blockbuster Transformers: Revenge of the Fallen, Devastator can disassemble into six, smaller, fully functional Transformer vehicles. With its motion-activated sounds and movie-accurate detail, this toy is a must-have for any Transformers collector, ages five years and older. Transformers: Revenge of the Fallen, Devastator Ages: 5+ Requires: 2 "AA" batteries (included) Phillips screwdriver Adult unpacking/assembly What We Think Fun factor: Durability: Ease of assembly: Educational factor: The Good: A large, detailed Transformer toy that's six toys in one. The Challenging: Tough vehicle-to-robot conversion may be too much of a challenge for younger children. In a Nutshell: A massive Transformers toy that does justice to its movie inspiration; great for young fans and older collectors alike. Pulling a lever will cause Devastator's "Vortex Grinder" to open and light up.View larger. At over a foot in height, Devastator is one of the largest Transformers toys ever made.View larger. Your Own Transformers Experience Staying true to the movie, Devastator is massive, standing well over a foot in height and dwarfing most other Transformers toys. He is a solid, heavy, and well-built toy. Pulling a lever on his chest causes his mouth (called the Vortex Grinder) to light up with bright, neon-green LED lights. The lever also triggers battle sounds and quotes taken straight from the movie. Devastator isn't the most flexible toy around. Because of his size, he can be a bit cumbersome to play with. However, his elbows and knees are articulated, which makes him easier to position and balance. He also has realistic details, which gives him value as a collector's replica. Devastator consists of six smaller construction vehicles: the Constructicons. These detailed vehicles are painted in earthy colors suited for their rough construction jobs. Together, the Constructicons form a complete construction team. There is a bulldozer, a dump truck, an excavator, a scoop loader, a mixer and a crawler crane. They prove to be very maneuverable on a hard surface, able to make hairpin turns easily. However, it should be noted that, unlike their film counterparts, these vehicles do not transform into robots individually. An Enjoyable, Challenging Assembly Devastator might be one of the biggest transformers around, but it's also one of the most difficult to put together. Parents should be aware that the Devastator requires some degree of finesse to assemble -- and in some cases, strength. Some of the snapping parts are especially tricky to connect together, and prove difficult to pry apart. The toy is labeled as a Level 4 conversion, so younger children will have difficulty converting the toy by themselves. It took our tester (an experienced Transformer player) nearly 15 minutes to figure everything out. Still, putting the toy together should provide a constructive challenge for older kids. What's in the Box Constructicon Devastator (batteries included). Devastator disassembles into six smaller Transformers vehicles.
The ultimate Decepticon weapon has arrived on Earth, and nothing will ever be the same. Constructicon Devastator is the biggest robot, ever - towering above Autobots and Decepticons alike. As his Vortex Grinder snaps open and glows with power, all before him quake in fear, knowing the destruction is inevitable!

How The Cobra Power Inverter Works The Cobra power inverter is an electronic product that has been designed and built to take low-voltage DC (Direct Current) power from your automobile or other low-voltage power supplies and convert it to standard 115 volt AC (Alternating Current) power like the current you have in your home. This conversion process thereby allows you to use many of your household appliances and electronic products in automobiles, RVs, boats, tractors, trucks, and virtually anywhere else. Cobra 1500 Watt Output Waveform Some very sensitive electronic equipment might not operate satisfactorily on "square wave" or "modified sine wave" power. The output waveform of the Cobra Inverter is a "square wave" or "modified sine wave." It is a stepped waveform designed to have characteristics similar to the sine wave shape of utility power. A waveform of this nature is suitable for most AC loads, including linear and switching power suppliers used in electronic equipment, transformers, and motors. AC receptacles With three ground AC receptacles, you can connect and power multiple devices at once. USB Output The 5-Volt USB output allows charging and operation of modern portable devices, such as iPods, BlackBerrys, and cell phones. Remote On/Off Switch Capable An optional Remote On/Off Switch can be connected to the Remote Jack, allowing you to turn the Cobra power inverter on or off from a convenient location when the inverter is installed out of reach. Safety Features The CPI 1575 will notify you with a flashing meter and alarm sound when there is a power problem, and will shut down for protection in the following situations: Current Overload Protection--If the inverter is overloaded, it will shut down to protect itself. Short Circuit Protection--If the AC output of the inverter is short-circuited for one second or more, it will shut down to protect itself. Low Voltage Protection--If the input voltage drops to 10.0V or less, the inverter will shut down to protect itself. High Voltage Protection--If the DC input voltage rises above 15.0V, the inverter will shut down to protect itself. Over Temperature Protection--If the internal temperature rises to 40 degrees C (104 degrees F), the inverter will shut down to protect itself.

Current Transformers and Its Factors
A current transformer is kind of electrical instrument, which is produced especially to provide a flow of current in the secondary circuit that is correctly perpendicular to the amount of current flowing in its primary circuit. To calculate current and monitor the operation of power grid Current Transformers are used widely and it is classically defined by its current ratio from primary to secondary.
Current transformers are most widely used in metering and protective relaying in the electrical power industry where they make easy the safest obligation of a huge amount of currents, regularly in the presence of high voltages on the circuit. The current transformer securely cut offs to measure and to manage a circuitry from the high voltage essentially available on the circuit. Current transformers are normally controlled by passing a single primary turn under a well-insulated toroidal core with enormous turns of wire wrapped. Current transformer is further used to measure the flow of current and as well in monitoring the operation of the power used. The CT is fundamentally defined by its value of current ration flowing from primary to secondary.
There are some factors that improve the current transformer’s accuracy. They are like burden, rating factor, physical CT configuration etc.
The value of impedance is the outcome for the burden in a Current transformer circuit. The basic items that are reasons for burden in current calculation circuit are intermediate conductors and switch blocks meters and the sources are the conductors among the meter and the CT. Further the problem of producing high resistance occurs due to placing a substation meter at some level of distance from meter that could beat by using current transformer with 1 amp that produce low voltage drop.
The Rating Factor of current transformers that are dependent on ambient temperature, is a factor used to determine the correct maximum measurable primary current by multiplying the full load of a CT. In order to maintain the accuracy level in rising of ambient temperature, the CT would have low capacity, and the rating factors of the CT’s would range from 35 degrees Celsius and 55 degrees Celsius.
Another important factor for accuracy of current transformer is Physical Current Transformer Configuration. If in case the conductors are not really centered in circular or oval, the inaccuracy occurs in CT and this needs to be notified for correct accuracy. Normally, the CT’s are constructed in many ways like passing a single primary turn by way of well-insulated toroidal core wrapped with many turns of wire. To calculate the waveforms of high frequency or pulsed currents within high pulsed power systems wideband current transformers are specially used.

There is power on the cable but lights will not turn on. At switch 3 thin wires. at lihgt 24v transformer.HELP
the transformer clicks when I turn the switch on but lights will not turn on. There is power coming into the socket though. The wires at the swtich are very thin, that's why the transformer is up there. But why lights won't turn on if I test for power and it is there by the socket? Help.
a transformer doesn't click, that is a relay - is it incandescent, fluorescent, part of a ceiling fan assembly?
