Question: Is this unit a 240V, and is it ok to use it in USA because of that?  Or has the 240V issue been resolved?
Document: I ordered this AC adapter from Amazon to power the Tascam DR-05 that I also ordered from Amazon. The adapter I received is a 240V adapter. When I opened the box I was caught by surprise, thinking "WTF is this?" I am an American, and in America we use 120V/60HZ. So why is Amazon selling me a 240V/50HZ adapter? Of course the product description doesn't state what the voltage is.
The adpaters work fine, but I only give two stars because of the price.Also, another review indicated the power supply is 240 Volts, and indicated that is a problem because America is 120 voltage. Mine is a 240V adapter and I have not had a problem using my first adapter in America.
Does exactly as advertised and I'm very happy with the unit. Would like an automobile plug adaptor for it -even tho it would cost more.
But this is so simple that it's a no-brainer: just plug this power unit into the mini-USB on your Tasman with the mini-usb cable that comes with the Tasman recorder and and plug this power unit into an AC power source.
I was surprised this unit doesn't come with a USB to USB cable. Look closely at the picture -- all you get is the adapter and a power cord. You have to fend for yourself on the USB to USB cable. With a price tag in the high twenties, that's a real disappointment.
Because I was not informed of the fact that Tascam had changed the plug that goes into the recorder from a standard analog/digital round plug to the special computer plug. It took a lot \of searching on my part to find the jack on the recorder that fits that plug.In other words, even though the unit carries the same part number of power supply I have for my other recorder, it is different.
The PS-P515U AC adapter does the job when you need AC powered recording. The unit is very small and comes with the power cord. However, it does not come with the mini-usb to USB cord. If you've purchased a Tasman field recorder that this power source us suitable for it should have come with a mini-USB to USB cable which is suitable to power the Tasman with this power unit. The paper instructions that come with it are essentially useless and is included for regulatory reasons.
a good AC adapter for my portable sound recorder. it is great to not to use batteried if you can.
I bought this for my sister who reports that it worked great. She had been going through a lot of batteries, so was happy to have this to use instead.
A most in combination with the DR-05, it is nice to use battery power when on the road but at home, AC is better
Answer: I have a 515 unit in hand and on the back it indicates the accepted input voltage to be 100v to 240v AC, 50-60 Hz.  So, to answer your question, it is not specifically a 240v unit, it's a "universal" type in that it accepts US standard voltages and European (240v 50hz, similar).  If you have any concerns you should call TASMAN directly (go to their website www.tascan.com) or call them at  323-726-0303.
