    Works as aadvertised

    So far, the power supply is working great. It replaced a 1a 12v power supply, but I haven't pushed it too far yet. We will be using it to power up LED lights installed on emergency services vehicles. But I ordered it so I could power up other mobile electronics; police radios, gun locks, sirens, light bars.

    Excellent poewer supply for low voltage landscape lights

    I overloaded my 20 year old power supply for my low voltage landscape lights and was surprised to find that its hard to find a 12v dc low voltage landscape power supply that would support 80-100 output watts. Apparently the advertised 120 watt systems are actually 2 60 watt supplies which wouldn't work for me. I found this system which works great! My power supply is in the basement so weather is no problem. I'm running 80 watts plus wiring and could easily add a second 60 watt system I have if/when it should fail. The power supples for low voltage ladscape systems are very expensive (timers,

    Perfect for any lighting projects.

    Works Great! No major heat issues. For the price I would recommend this to anyone working with lighting or tech. Very durable and steady power output.

    Bring your own cord and adjust pot to obtain desired output between 11.5 & 15.5 VDC.

    The unit fan is a bit loud but it keeps supply cool!.I had no trouble adjusting output anywhere between 11 and 15 VDC Using pot on unit. Be aware there is no cord included to plug in to AC supply outlet. Unit comes with 110VAC selected if you are outside the U.S.A. you will likely need to switch it to 220VAC input At selector switch on the side.Unit arrived undamaged despite poor packaging and works well so far! Seems to be a good unit for the low price and easy to install

    I got it overnight

    No on off switch, used it at Field Day worked with no problem. Voltage did NOT vary a 10 th of a volt while transmitting100 watts of power. Price is very reasonable for a quality product.

    Very responsible vendor

    These are good units, but what is more important is the support from the vendor. I had a unit fail after two months. I reported it to GESD, and within a week I had a replacement unit that they shipped from the Amazon warehouse. These folks stand behind their product. I would buy again from them in a New York minute.
