12V 30A Power Supply

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.

I used this to replace the existing one from my old Anet A8 printer and it was perfect. Checked the output showed 12.02 volts at nominal cold power on. The power is stable and reliable so I'm happy with this purchase!

Works very well.

Works great. I have several that I use with no issues

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.

I'm running this power supply to power about 6 low voltage dimmers in my Home Assistant system. The Alitove provides good consistant power and the fan is relatively quiet when it needs to turn on. It has a number of positive and negative terminals and it is easy to connect.

The unit arrived promptly and in very good physical conition. I place it into service on my workbench and powered 7 x 16 ft LED Strip lights and all worked well. Total current draw was about 16.5 A at 12 volts. The case started getting warm after about 15 minutes and the automatic cooling fan came on but stopped after a few minutes and never came on again. The case temperature (external) rose to about 55 C and was too hot to touch. I contacted the seller (Alitove) to see if this was normal (didn't seem so to me). I would have expected at least that the cooling fan would be running but it wasn't. The seller responded as quickly as could be expected and after describing the situation and my setup ( with pictures) they sent me a new unit which has been working perfectly. The external case temperature now only reaches 25 C under the same conditions as previously. I am very happy with the power supply and needless to say also with the excellent customer service. I would not hesitate to buy from this seller in the future.

I ordered this item with some trepidation after reading reviews showing components and wiring melting. I'm guessing that the 30A rating is more of a maximum instantaneous load than a steady state rating. The secret seems to be to run this well below the claimed power level. My Xiegu G90 draws about 6 amps or less on transmit, so the power supply is loafing, and I haven't heard the fan come on at all. For hams, the bad rap on switching power supplies such as this one is that they generate a lot of electrical noise and interfere with reception. So I put ferrite chokes on each of the 12V power leads before running them to the transceiver. I tested the transceiver on battery power and then with this power supply, and could hear no difference at all in the noise level, and no difference on the S-meter. I can't speak to reliability, since I've only used the supply for a short time, but when comparable power supplies from ham outlets run $150 or more, this is a pretty darn good deal. Edit 4/5/20. Power supply worked perfectly for about two weeks, then voltage dropped suddenly to between 6 and 7 volts. 220/110 switch remained on 110. Voltage adjustment potentiometer had little or no effect. Returned unit to Amazon for replacement, which apparently had to be sent from China, because it took several weeks to get here. New power supply works perfectly -- for now. I will update if this one also conks out. Dropped a star because I had to replace it. Edit 4/24/20: Replacement power supply conked out in precisely the same way as the first one. It's now putting out about 5 volts. I'm undecided as to whether to return it yet again for a replacement or just to give up and rely on the rock solid Bioenno battery I bought initially to power the transceiver. In either case, I can only give the unit one star as it is completely unsatisfactory for two consecutive units to fail in less than three weeks. Too bad, since when it worked it was completely satisfactory.

المنتج كويس جدا وصل جديد زيرو وزي ما مكتوب 30 امبير فعلا لو هتحتاجه لمشاريع هنديسه هايفيدك جدا

Too big to fit in. Needs a lots of space.

Works great for my diesel heater 12v

Works as described

I bought this to replace a failed "power brick" for a 4-drive hard-disk case. I adjusted the DC voltage slightly (about 0.1V), checked for noise on the DC output (using a scope) then powered up the drive case and rechecked the voltage/noise and verified that the voltage remained "dead accurate" and the power remained clean. The original power supply was rated at 12A so this supply is nicely overrated and the internal fan never runs so it's "dead quiet." The drives have been in active use for a few weeks now and all is well ... a reasonable cost to save a drive case that cost over $400 US, when new.
