Nice inexpensive DC regulators

I really like these units. Output is adjustable rated to 3amp but I'm only running about 1.5a. Does not seem to get hot.

These are great for MCU and other projects where I need various supply voltages.  They are easily connected and adjusted.  I plan on ordering a few more in the near future.

What a nice little power supply, perfect for my applications and circuit tests.  The course and fine adjustments are a nice feature and the voltage settings are dead on accurate.

Well made and suitable for the intended purpose.  DC resistance measured between 50.5 and 51.0 Ohms.

Great little power supplies for my 12 Volt needs, At this Price, you can't go wrong & if you need extra units, these are your best bet, as at these prices, it sure  bets shelling out Big Bucks, for one While these are on sale.

APC LE 1200 the best regulator for the price. Maintained 110v, 120v and 127v selectable output. 80-150V input. Used this for my 1000 watts gas generator to use with our sensitive electronics. Work like a charm. Highly recommended for those who's power fluctuate from 80-150VAC. Again it's regulate the output on steady 110, 120 and 127VAC -/+1

Work just fine to replace my leaking regulator

These are great for low-voltage DC solutions, where you can't risk a power disruption due to an accidental cable yank.  I used these in conjunction with USB 5v to 9v converters + dummy batteries on a Lumix GH4, G85, and GH5.  They work great, and could have so many other uses.  Shipping time was as expected, but keep this in mind when ordering.

These are great.  I got these to act as small low voltage relays to open/close contacts with a not common ground in a separate circuit where I couldn't use a PNP or NPN transistor.  They're small, easy to wire and work as expected if you follow the diagrams.  Using other transistor and relay combinations might be cheaper, but these are so easy and simple I just dropped them in my circuit.

Build quality: all metal chassis, very compact, seems like good quality connectors and LEDs.

Functionality: Works as advertised,  I have 2 on my board.  The outputs are isolated... I have combined the 12V from my 2 to create a 24V for one of my pedals (Voodoo Labs sells the cable).  I haven't tried combining in parallel for more current so I can't guarantee that.  I also haven't tried putting the outputs into overcurrent, but they are supposedly individually short circuit protected.

Value: For the price, a no brainer.  A fraction of the cost of the popular brands.

Pretty pathetic documentation, but I'll accept that for a good deal.

I use these switches for distributing switched power to various elements on my RC rigs, like video transmitters, lighting, camera power supply, etc. Simple enough, with servo connector and JST connector already in place.

This power supply arrived with the insulator nuts for the terminals missing.  In my case this was not essential as i discard them anyway but does show a lack of quality control at Tripp Lite.  The unit works well and delivers a consistent DC power source at 13 volts.  Works well with the electronic RFID readers i am powereing with it with negligable radio interference.

Purchased this item in order to convert DC 12V to DC 5V.
Currently using this single step down converter to feed 5V to 4 different devices simultaneously.
Voltage indicator is dead accurate and potentiometer is easy to control. In rather demanding current draw, the output voltage never seems to drop below to the set voltage. Pretty impressive device.

These are alright and the ones I used worked fine. They are not what I would call professional quality. If they are exposed to weather or used for anything other light duty applications, you'll be replacing them often. For the price, and the amount of clips you get, it's a good deal.

 They're good for low amp trickle chargers, test leads and low volt jumpers.

Worked just fine to power 2 runs of 1.6 watts per foot strip LEDS. Just a slight drop in light intensity by the end of the run.
Transformer slightly warm when running a full load but expected. Quiet operation no humming or buzzing. A bargain imo.

I bought three of these for Digitrax DCC power supply. All three perform very well with no complaints.

Good price on a variable regulator for my forge. Probably good to supercharge your grill too. I like some adjustability rather than fixed pressure cheapo regulators that come with your grill
