User Sanford Erickson Asked:

Does the output plug come with a choice of polarities? I require the centre connector to be + positive and i don't want to have to re-wire unless necessary.

Our Technician Answers:

Hi Eric... All the connectors on our 12V power supplies follow the standard polarity, which is center positive. This means the inside of the barrel is positive, and the outside is negative... It is possible to switch the polarity by cutting the 2 wires, and switching them around and reconnecting them with electrical tape... This is safe and effective.

User Keith Merrill Asked:

My sit-down Everlast (Brand) exercise machine needs a replacement AC adaptor to power a simple "electronic" display which shows speed, mileage, etc. which are measured, I'm sure, by the speed and revolutions of the pedals. But I can't find a replacement with similar Numbers. There are all kinds of 12v adaptors around but I haven't the knowledge to know how specific one must be to order a replacement (amps etc.). Following is all the data printed on the label: AC adaptor Class 2 transformer, model ADB-0900500. I/P AC 120v 60Hz 9W. O/P 9V 500mA. Thanks for helping me out. Based on your reply (including if you will, if you have the replacement part and your price) I can then move ahead accordingly. Keith Merrill

Hi Keith... Unfortunately we don;t carry anything that is 9A...

User Mike & Missy Asked:

My husband is a paranormal investigator so I am constantly searching & purchasing audio, video, & surveillance equipment, so I actually have a couple of questions. Any assistance &/or advice you can give will be greatly appreciated. (1) While moving, I ran acrossed an AC/DC power adapter (all by its lonesome) with the printing: Model # DY-08050/ Input: 100-240 VAC (50/60Hz) Output: 8volt--500mA. Do you have any idea what device this might be for? We're thinking it could be for one of the Canon ZR500, or ZR700 camera's but are not prepared to chance plugging it in w/o further advice. (2) We are also searching for a mini portable power source ( to charge) in order to power wireless mini DV camera/camcorder's, & IR lights. Lightweight enough to "dangle" from the Swann wireless surveillance camera's would be GREAT! But ANY suggestions are greatly appreciated. Please respond at your earliest convenience, & we thank you for your assistance. Respectfully, Mike & Missy PostScript: Listed below are devices they would need to power: (1) Swann wireless camera's,(2) Sony (Handicam/Mini DV's/DCR/DVD's/Cybershot camera & Hi-8/S-VHS-C/ & VHS-C (3) Canon (Elura,ZR500/ZR700/DCR/DVD-100/DCR/DVD-200/& ELF series. (4) & a few misc. camera & camcorders (DGX/Olympus/Sylvania/Panasonic) Thank you again! Respectfully, Mickey & Missy

Our Technician Answers:

Hi MIke and Missy. While I cannot answer about specific devices and brands, I can let you know how to find the power supply you need yourself. All you need to know is the Voltage of the device, and the Amperage it uses. The voltage has to be an exact match, so if your devices uses a 12 Volt power, you will need to use a 12V power supply. Amperage on the other hand, is a minimum number. For example, if your device uses 9 Amps, you can use a 9 Amp adapter, or a bigger one.... So a 10A power supply can handle an 9A, and 8A, a 7A, load etc... The device will just pull what it needs... So if you match the voltage and amperage, the device will work...

User Guillermo Padilla Asked:

need a 12 volts 1amp but need it white, do you carry them?

Our Technician Answers:

Hi G. All our in stock power supplies are black. For an order of 100 units of more, we can make them in any color..

User David Asked:

Looking for a adapter input 100-240v 2.0a 50/60hz. Output 12v---- 7.5a. Do you have one

Our Technician Answers:

Hi David... For a 12 Volt device that requires 7,5A of power, you would use the 12V 8A power supply. That power supply can handle any load UP TO 8A.
