    Default 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!

    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.

    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!
