ALITOVE AC 110V/220V to DC 12V 30A 360W Universal Regulated Switching Power Supply Transformer Adapter LED Driver for LED Strip, CCTV Camera System, Radio

No instructions manual, however was easy to figure out. I needed lights inside my semi trailer and had bought a light bar kits which never was used.So, I had 5 lights LED 40 inch , 20 inch and a few single spot lights. After wiring the box and testing, everything worked flawless. I would recommend this anyone wanting a 12v power supply simple solution for my project. You can also adjust the voltage on this unit.

Update 9/21/23 So far no negative issues to report. Bought a second unit and am now running them parallel providing a 60 amp base supply at 13.8 volts...both units set at exactly same voltage with a 4 decimal volt meter for exact match to run a larger linear amplifier pulling as much as 50+ amps for extended periods (long QSO's or talk sessions). I have not experienced any issues with heat buildup, power fluctuations, voltage drop is negligable and mine have not shown any problems with grounding (my entire station is well grounded) and I do check my individual components - Not dismissing others comments, just saying I have not experienced a grounding issue. Have recommended same unit to my Son who is also a radio operator.Original post:I am using this at14.26 volts to power a small Ham Radio Amplifier providing solid voltage (love the very adjustable output voltage) and solid amps during peak transmissions. The unit provides adequate power to provide a solid 200-225 watts out to antenna from the supply. The thermal fan control works (no constant fan running like some other of these smaller supplies), voltage drop is less than .3 volts at the 225 watt output peaks....we shall see how it goes for long term use but so far I'm pleased with performance per dollar....will buy again for a parrallel twin supply setup if I see no issues over the next month (will report back).For those HAM's worried about whether for HAM or CB, I'm a licensed Ham Op. so you can save those negativities for someone else.

Good powers by dependable looks worthwhile.

UPDATE: The original review was written based on the unit shipped to me. The seller quickly provided a replacement as a warranty which I have now had in operation for a couple of weeks. The unit works as advertised. As a higher power unit there is an integrated fan for cooling. This didn't work on the original unit which may be why it failed in the manner it did. The fan does generate some noise when on but it does cycle on and off as needed. You may want to keep this in mind depending on your installation requirements.ORIGINAL REVIEW: Bought the 30A power supply to run multiple 5 meter LED light strips (sold by same seller). It is a simple unit with good value for what it is supposed to do. The lack of any real instructions is not a hinderance. Upon arrival I attached a power cord (3 wire) to check operations. Output was nominally 12VDC with some slight ability to adjust this as expected. During the next month I installed the power supply and one string of LED lights as part of an in progress project. Seemed to work well but then I noticed some dimming of the lights over time. (a single 5M strip is well under the max rating of this unit). Measured the voltage at the LED strip and discovered it was now 9.5VDC. To make sure this wasn't an installation issue with the LED wiring I disconnected them and measured again at the power supply. Same result. Subsequent testing showed that the unit's output decreased over its on time regardless of load. I have measured it as low as 8.1 VDC with the adjustment turned all the way up. Either a bad unit (trying to get in touch with seller for a warranty replacement but not easy) or a bad design.Update 4/3/2020: the seller has offered to send a replacement unit. I will update this review once that one has arrived and been checked out.

Excelente seller, fast, good shipping and packaging procedures. Products works like a charm. Thanks AMAZON it came in a box, but no wrapping, please use a wrapping or put fragile on the box. I bought from him 3 items and he was an excellent seller ALITOVE. It made my project an Scalar machine, worked again, for zapping and getting rid of all bacteria and parasites right out of my body. A power supply solid 12 Volts 5amp, let's see how it goes.

Very stable voltage and quiet electrically. Would recommend purchase . Will purchase another. I have been using it to power communications equipment.

Works good even in the rain (not recommended)
