VCI-100 9V Power Adaptor question

Hi everyone,

I came across a 9V power adaptor with the following specs,

Model no: DV-9100S
Input: 120VAC 60Hz 4.5W
Output 9VDC 100mA
Class 2 Transformer

Is this safe to use to power my VCI 100? Thanks!

Anyone…Anyone??? Kinda weary to just plug and go!

i used a multi-volt adjustable power adapter and it works like a charm. as long as it’s 9v it should be good to go.

4

cool, i did do a search and someone else was using an adaptor that was 500mA. I’m not an electrical guy so I was only hesitant about the 100mA part

Taken from the specs on the vestax website:

Power：9V, 150mA

Adoptor：DC 9V 500mA

Dimensions：360(W)×252(D)×35(H) mm (Excluding knob height)

Weight：2.6 kg

Any harm in running the one that I mentioned?

i would rather just goto RadioShack or Fry and pick up a self multi adjustable power adapter. you just have to make sure you set the +/- correct.

This may sound stupid but how does one set it correctly or know how to set it correctly. I am a dunce with electrical. Electrocuted (mildly and by accident) as a kid!

I wouldn’t use the 100ma one. You run the risk of losing power at a crucial moment. Do Use 500ma. Try not to use higher than that, you can fry your controller.

Using the maufacturers spec is good practice. I know because I have blown equipment with the wrong adapter - learning about electronics the hard way.

Zac is kind of right! Using an adapter higher than 500mA will not fry anything, it is just a waste of money. As an Avionics Technician by education and by trade, I know for a fact that the VCI-100 will only pull what it needs from the power adapter.

Think of it another way. If you get a computer with a 600W power supply, the computer will not necessarily use all 600W. It will only consume what it needs. If you use a power adapter that only supplies 100mA, for example, the voltage will drop at the VCI-100 and it may not function properly.

Since the current draw of the VCI-100 is 150mA, the power adapter needs to have at least a 200mA capacity (the extra 50mA is for safety margin). So, anything more than 200 should be great!

My bad - thanks Rick, for the clarification. Last time I blew a piece of hardware was a long time back, and thinking it through I think I had the voltage wrong and not the mA. (luckily only minor project) What you’re saying makes perfect sense. So mA too low = asking for a drop out, but higher than spec = no problem. What happens when you are really going overboard with the mA though? Like spec=500, but adapter=1000?

Nothing really. The adapter will just idle along not really working anywhere near its limits. You would be fine, the penalty would be too much money since the higher the current rating, the more expensive they are. You would also pay a size and weight penalty since the higher the rating, the bigger and heavier the adapter has to be.
