Average rating: 4.Our televisions are best for RVs, semi-trucks and many other automotive and off-the-grid applications.

Our 12 Volt TV's are powered entirely by 12V DC power which is native to your vehicle without the need for special adapters or converters which tend to waste large amounts of power. These TV's host features commonly found in home TV's including the new digital tuner. Adding convenience to travel has never been easier or more affordable. Bring along healthy home-made food, drinks and snacks.

Keep them cold using our 12 Volt Coolers or 12 Volt Refrigerators until you're ready to enjoy. So, what's the difference between coolers and refrigerators? In short the difference is the ability to reach very low temperatures. While our 12 Volt coolers are perfectly suited for travel in general, some people need or prefer a thermostat controlled refrigerator with the ability to freeze food, drinks and medical supplies. Add a little comfort to your travels with our 12 Volt Fans and Heaters.

All of our fans will plug directly into the 12V lighter socket, but many can be hard-wired into the vehicle's electrical system. Many of our 12 Volt Heaters are powered by the 12V outlet, but some require direct to battery connections.

That means that the winch will require amps at 12 volts DC when pulling its rated load.

It is intended to be used on a car, truck, or ATV, and be connected to the vehicle's battery. See Full Answer. What is a 12 volt DC power outlet? The 12V socketalso known variously as a car cigarette lighter or 12V auxiliary power outletis the primary method by which power is delivered to portable electronics in cars, trucks, boats, and in a handful of other contexts.

The cigarette lighter receptacle also called a cigar lighter receptacle or cigar lighter socket in an automobile was initially designed to power an electrically heated cigarette lighter, but became a de facto standard DC connector to supply electrical power for portable accessories used in or near an automobile. The "outlet" is the cigarette lighter although I think that none of the new cars actually have a cigarette lighter - it's simply the place where one plugs a GPS or cell phone charger.

The cars are not built as 'no smoking cars ' by the factory, so cigar lighters are still fitted as standard for that model of car. The spark ignites the flammable gas causing a flame to come out of the lighter which continues until either the top is closed naphtha typeor the valve is released butane type. What is meant by DC power supply?

The term DC is used to refer to power systems that use only one polarity of voltage or current, and to refer to the constant, zero-frequency, or slowly varying local mean value of a voltage or current.

For example, the voltage across a DC voltage source is constant as is the current through a DC current source. Washington was named after the first U. President, George Washington. The " D. What does a DC power supply do? Such power supplies will employ a transformer to convert the input voltage to a higher or lower AC voltage. A rectifier is used to convert the transformer output voltage to a varying DC voltage, which in turn is passed through an electronic filter to convert it to an unregulated DC voltage.

Like other power suppliesan SMPS transfers power from a DC or AC source often mains power to DC loads, such as a personal computer, while converting voltage and current characteristics.

In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. Other common names include plug pack, plug-in adapter, adapter block, domestic mains adapter, line power adapter, wall wart, power brick, and power adapter.

What does 12v DC mean? For example: a 12V AC power supply has an alternating voltage which will make an alternating current flow. An electrical signal is a voltage or current which conveys information, usually it means a voltage. The term can be used for any voltage or current in a circuit. What is a DC input? Usually an adapter is a device which is used to interface a DC operable device to an AC utility supply. Usually, small signal electronic gadgets like computers both desktops and laptopsmobile phones, electronic trimmers etc require a much reduced DC input as compared to what is provided by the power grid.

What does 12v 3a mean? Amperage is the amount of power your device uses.In which we have to give power supply on pin-1 and pin Now we have to connect output power supply wires. The output power supply will give always constant 5V DC power supply. Now the wiring of voltage regulator is fully completed and the next step is we have to check the circuit. In this circuit I give 12V DC input power supply and as you can see in the display digital multi meter the output power supply is almost near about 5V DC.

In addition to the decoupling capacitors, this needs to be on a HEATSINK or the regulator will overheat and fail if you try to draw any appreciable power. This instructable is half baked misleading and inaccurate. Baldengineer knows what he is talking about. The LM needs the capacitors listed in the datasheet to have stable enough voltage for most components.

Look at his guide. Tip 1 year ago on Introduction. Please do not follow the instructions in this guide. You MUST use decoupling capacitors on both the input an output of a regulator for proper operation.

Reply 1 year ago. I am sorry, but that reason is incorrect. You absolutely do need to use decoupling capacitors. Capacitors on the regulator's input will help extend the operational life of the battery.

Batteries have a very high ESR and various current draws will shorten their operational life. For rechargeable batteries, this means shorting their total operational life. The output of the regulator needs, at the least, small decoupling capacitors to react to relatively high frequency changes by the load.

No linear regulator is stable without output decoupling capacitors. Please update your article so that uninformed users are not mislead by incorrect circuit design. Thank you for the mention! You are absolutely correct. This design needs the decoupling capacitors. At the very least, they need the values recommended in the 's datasheet. By Utsource Follow.

NeilRG 3 months ago. Reply Upvote. SethB62 1 year ago.A DC connector or DC plugfor one common type of connector is an electrical connector for supplying direct current DC power. Compared to domestic AC power plugs and socketsDC connectors have many more standard types that are not interchangeable.

The dimensions and arrangement of DC connectors can be chosen to prevent accidental interconnection of incompatible sources and loads. Types vary from small coaxial connectors used to power portable electronic devices from AC adaptersto connectors used for automotive accessories and for battery packs in portable equipment. These extra-low voltage connectors are rated at or below VDC. Small cylindrical connectors come in a variety of sizes. They may be known as "coaxial power connectors", "barrel connectors", "concentric barrel connectors" or "tip connectors".

The intended use of these plugs is on the cable connected to an external AC adapter power supply. The matching jack or socket is permanently fitted to the equipment to be powered. Some of these jacks contain a normally closed contact, which can be used to disconnect internal batteries whenever the power supply is connected, avoiding the risk of battery leakage or explosion posed by incorrect recharging of the batteries.

Cylindrical plugs usually have an insulated tip constructed to accept insertion of a pin. The outer body of the plug is one contact, most often but not always the negative side of the supply.

Inverted polarity plugs can, and do, damage circuitry when plugged in, even if the voltage is correct; not all equipment is equipped with protection. A pin mounted in the socket makes contact with a second internal contact. The outer plug contact is often called the barrelsleeve or ringwhile the inner one is called the tip. There are a wide variety of sizes and designs for these power connectors, and many appear quite similar to each other yet are not quite mechanically or electrically compatible.

The Japanese EIAJ standard includes five different sizes, with each supporting a specified range of voltages. Most of the other coaxial DC power connectors have no specified voltage association, however.

Generic plugs are often named for the pin diameter they are designed to take. Many non-proprietary co-axial power plugs are 5. Two pin sizes are common in the jacks for this size plug body, 2. If the size is not known, it is difficult to distinguish by eye or measurement between the 2.

Maximum current ratings commonly vary from unspecified up to 5 A 11 A for special high power versions from some companies [2]with 1 A, 2 A and 5 A being common values. The 'tip' i. Connector size does not usually indicate the voltage. It is not possible, except for some proprietary connectors, to reliably infer any information on power parameters current, voltage, polarity, even whether AC or DC by examining the connector.

Snap and lock DC power connectors look similar to Mini-DIN connectors, but have either 3 or 4 thicker pins and a slightly larger mating shell. Because of this they do not mate with any of the standardized Mini-DIN connectors. Some devices, however, use a true 4-pin Mini-DIN connector for power instead, presenting the possibility to mate such a connector with the wrong port such as an S-Video output.

Molex connectors were frequently used as DC power connectors in personal computers, for floppy, hard disk, and CD drives. SATA peripherals use a different style of connector.

The International Electrotechnical Commission IEC has produced a standard for a system of 2-pin plugs and socket-outlets for household and similar purposes in fixed and portable applications, either indoors or outdoors.
