  • Very Nice Item

    posted by MRXC90

    Reasonable price. If your looking for a Constant voltage power supply? this is certainly not a bad deal. It does what it states. Also interesting to know is you it has a dial on it so you can adjust the voltage down to approx. 11.1 Volt. Seems rather unimportant, but it often is useful to limit voltage a little bit lower than 12 volt. The same way you can beef it up to +13V if you ever want to challenge your LED's ;-)
    Be aware it isn't waterproof (obviously, but never the less). Although it's pretty good caged and shielded, one must be aware that 12Volt and 220V are sitting pretty damn close to eachother. A mistake is easily made. Better would be to have them separated at different sides.
    Does what it should do. Deliver a constant 12 Volt.

  • Very good purchase

    Just like such an items on dx.com.We have the very same items (I think from the same factory) locally just twice a more expensive.And I did not deeply research the scheme but I think that the cons from previous review here just wrong - you do not need any fuse (fuses are inconvenient in any case and most of the time you and with shortened one :) - just because the protection is inside the scheme - "Safety design with shortage protection, overload protection and auto voltage switching. Regulated voltage & current output."
    Great.
    Recommend to anybody.
  • Neat little power pack for hobby projects

    posted by PA5UL

    Sturdy stainless steel housing, small size allows you to place it inside equipment. Neat printed circuit layout, good component placement and soldering, looks really professional. Little green LED indicates power is available.
    No user documentation is supplied but that is not really needed for standard use.
    Good value for money, neat little power pack for hobby projects.
  • Perfect product for PSU-checking

    posted by Tjeudx

    Great product; easy to use. It also has an internal speaker which give's pre-audible information about the connected power supply. An extra -handy- option I wasn't aware off.Product received in excellent packaging.
    I checked about six PSU's now; 2 out of 6 where -correctly- defective.Take care when connecting and especially disconnecting the PSU; don't use too much force when disconnecting. Start using a flat screwdriver to disconnect it horizontally by wiggling it left and right is a wise option to prevent breaking the connector from the internal pcb.
    Great, very handy product with various options; especially the powerbutton is a pro !
