Most of the countries use alternating currents (AC). DC stands for direct currents. All appliences and voltage transformers run only on AC electricity. There is no worldwide standards for the plug configuration. Plugs, plug shapes, electric outlets differ from country to country. For that reason you need to get a plug adapter, in order to plug your aplliance into foreign electric outlet. You still need a voltage converter, otherwise you might demage your applience or cause fire!

If you want a long lasting and more powerful, professional quality dryer, buy an AC motor dryer. A dryer with a DC motor is usually lighter and less expensive, however it will need to be replaced more frequently. DC dryers are best suited for at home use.

Also known as battery eliminator, universal AC adapters are used to convert AC electricity (i.e. 120V or 240V) to a desirable DC current (i.e. 1.5,3,4.5,6,7.5,9 or 12 Volt DC). Some battery operated items with DC input includes walkmans, baby monitors, telephones which can be used with AC adapters universally.

With DC (Direct current), the current always flows in one direction with no relation to change in time, as is the case with a dry cell battery or a car battery. (The DC output of Honda generators is for charging batteries only.) Alternating current, on the other hand, reverses its direction at uniform time intervals. Almost all-household electrical appliances are made to run on alternating current. Well, let’s use an example to illustrate why.

Both AC and AC/DC welders have a large transformer in them that converts the power from the wall outlet to a voltage that is proper for welding. AC welders simply convert the outlet AC voltage - DC welders convert the voltage AND change the AC from the wall outlet to DC. When the electricity is changed to DC, it has a polarity associated with it. AC (alternating current) power has no specific direction - it cycles back and forth 60 times a second (alternates).

AC adapter is not available for the WS-311M. When the recorder is connected to a computer, the computer's USB port powers the device.

Probably not, all countries use different standards for voltages, etc. We have special overseas adapters available for $20 extra. Yes. The Touchscreen has been specially treated to resist finger prints and make the touch surface - oil and dirt resistant. In order to do so, it does reflect some light and can be adjusted by tilting the screen or adjusting it so that lights are not directly behind the user.

All Watchdog systems will switch to DC battery power when the AC power is out, or when the main pump fails. But if the power is on, the AC/DC Big Dog can pump directly off of the AC wall current without depleting the battery. The other systems will only pump off of battery power.

Large offshore wind farms over 100 MW generally use HVDC (High Voltage Direct Current) because DC technology : DC emits about 5% of the electromagnetic radiation of AC which is good for elasmobranchs (sharks etc)

Yes, both AC power source or dry batteries can be used on our Techwinder. So you could use it anywhere in your home or office or store, or place it inside your safe or vault to safe guard your watch collection while winding your watch at the same time.

North American MA-3600VZ and MA-5002VZ amplifiers have 30 amp molded AC plugs, and North American MA-2402 and MT-2400 amplifiers have 20 amp molded AC plugs to meet regulatory requirements. AC adapters are not recommended, and may not meet local code requirements. Contact a licensed electrician for more information about AC connections and electrical codes in your area.

The charging light will only come on when a headset is placed in the charging cradle. It should indicate green if you place a headset into the front charging slot. Any Audio ports on the front of your television are Audio Inputs and are not compatible with our system. Audio Outputs are located on the back of a television, and are clearly labeled Audio Out.

This is a longstanding bug with the G1 and Pro 90 IS, and a relatively new bug with the G2. With the G2, it was introduced with a new camera firmware (G2 1.0.0.0 worked, 1.1.0.0 does not). We haven't fixed this bug yet since none of the active gphoto2 developers owned one of these cameras until recently (i.e. updated his G2's firmware). There is some more info regarding this at http://krixor.xy.org/fredrik/gp/canon-g1-ac-problem/. Good luck.

Yes. The AC adaptor kit (K-AC5J) is available as an optional accessory. We do not recommend the use of 3rd party AC adapters.
