Is 12 volt DC current 1500mA (1.5 A) dangerous?
Question:Can I get a shock from 12 volt DC current at 1.5 amps? The AC adapter that was included with my large Casio keyboard (WK-3000) converts the 120V current down to 12V DC 1500mA. The instruction manual says that dissassembling the keyboard creates the risk of electric shock, but I don't think it's true because it's only 12 volts DC. Not that I want to take it apart, but can this really give me a shock or burn?
Answers:
There are two parts to the answer.
Part one: 1.5 amps DC @ 12 volts is not a life-threatening current but can give you a pretty good shock and also has the potential to burn you.
Part two: Your keyboard has a number of capacitors and other current storing and altering components that can provide a very significant shock.
A good analogy is a TV set. A TV is connected to either 120 or 240 volts AC depending on where you are in the world. Inside the TV however, there are places where the voltage is transformed and reaches a value of several thousand volts in order to power the cathode ray tube. If you touch that part of a TV chassis you will remember it a very long time if you survive.
not really unless the 1.5 amps travel trough your body.
just a thought...can't you unplug your keyboard before you work on it?
it only takes one milliamp to shock you at any voltage and anything over 5 milliamps can be lethal....voltage doesnt shock you its the current that shocks you
1.5A might kill you, but 12V DC supplier can not create this current in human body. The capability of the power supply is 1.5A it does not mean that it will create this current in any case. 110V on the other hand can create a current that might kill you
Only if you're wet and touch the contacts which is unlikely. There are capacitors inside the keyboard that may be energized to several hundred volts but at such low current that you would only receive a slight sting. It's not recommended to work on any electrical device unless you're a qualified repairman or know what safety protocols to use.
well...the first thing I would do is unplug it so the risk of shock is automatically eliminated. Secondly, I wouldn't take it apart anyway because I wouldn't know how to fix one. And third, all you need is 1 Amp to go through your body to kill you.
That 1500mA is the max the converter can put out. When you get shocked the amount of resistance of your body determines how much current will pass through your body. At 12vDC it is likely that you won't get a "lethal" shock but to be safe, I wouldn't work on the keyboard while it is live. Aside from the shock hazard there is the chance of damaging the electronic components.
Remember that the load pulls the current, the source does not push the current.
no shock hazard at all only if you put yout tongue on it will feel a little tingle.
