DC to AC power cord Do they still make them if so under what name or product name?


"DC to AC" cords are not really a common item. They are called "Inverters". Typical inverters are 12VDC to 120VAC and are found in mobile applications to operate houshold current type (120VAC) devices. Inverters cost many times more than thier "AC to DC" or "AC to AC" sisters.

An "AC to DC" and "AC to AC" cord however, is a very common item. They are usually called simply "AC Adapters" and are sold in many electronics stores (Best Buy, Fry's, etc.) and electronic specialty stores (Radio Shack) and electrnics suppliers (MCM, etc.) Nearly all of them are designed to reduce the voltage in your home (120 VAC volts alternating current) to a different but usually lower voltage that is either AC or DC.

In order to select the proper AC adapter, you need to know:
(1) Input Voltage - this is the outlet voltage - often 120 volts in N. America, (2) Output voltage - this is the voltage the device needs and is often indicated near the jack, The adapted must match this voltage. (3) the device voltage type - this will be either AC or DC. The adapter must match the type as they are NOT interchangeable. (4) the size and type plug on the cord that will allow it to mate properly with the jack. There are many, many types and it should be tested for fit prior to plugging in and must match the device jack (5) the power requirements - this is usually shown as a number in Watts (w) and / or Amps (a). It is very important that the apdapter power rating is equal to or greater than the amount specified by the device. Failure to meet the requirements above can cause failure of the device, adapter or both.

I hope this helps and good luck!

Hi I want to purchase a AC DC 12watt Power Adapter for my old ARTEC 1236P Scanner. Can someone tell me if I can use my spare Input 230V ~ 50Hz 9W (Output - 12 to 9v) adapter? If not what should be the...


This will mean the input on the first device is 120 V and input on the 2nd device is 230 V. Right? If so Yes you can use this if it belongs to the same scanner however you will have to plug the power into a 230 V Circuit. You cannot adjust, manipulate, change the Volts/Watts/Amps under any conditions. If the 203 V (Out put) plug is the same as the 120 V plug and there is a place to plug it in to the scanner then go for it. Volts/Amps/Wwatts/AC/DC are very specific to a specific device.

Lost the power plug what kind is it


1. You can buy a new power plug here.
2. You look at the power connector on your scanner and try to find a replacement with the following specifications:

Input voltage/frequency:
  • 100 Vac, 50/60 Hz (Japan)
  • 120 Vac, 60 Hz (North America)
  • 230 Vac, 50 Hz (Europe)
Output voltage/watt:
  • 12 V DC, 15 watt maximum
If you try to find an AC/DC converter yourself, make sure that the DC plug has the right +/- polarity and right size.

Ran across your request for information about the cables needed for hooking up the Umax Astra 1220U scanner. The scanner require a standard older version USB cable that hooks the scanner to your PC. The second cable is the Power Supply Adapter cable. The information listed on the Power Supply Adapter is listed below. P/N 490081-03 Input 120 Volt @ 60 Hz 0.3 amps Output DC 12 Volts @ 1 Amp Model # RWP481212 You should be able to get the scanner to work as long as you can find any power supply that has the listed Input/Output ratings, an adapter that will plug into the scanner. Hope this help you. disaksen
