I have several other Samlex products and all are working great. This is a current limited power supply that I can use as a float charger for a battery bank that supports power outages and a Ham radio station. The SEC-1215UL will automatically recharge the battery bank after power outages as well as provide the operating power for normal operation. The battery bank is large enough to supply power for internet, computers and lights during the power outages in my area. Many of the parameters in the charger are adjustable and information from Samlex technical support provided some really good information on these adjustments for a special application. The other battery chargers that I have, are either simple chargers or have a lot of RF interference and it is great that this unit is both a smart charger and RF free. No RF interference was observed on any of the ham bands from 160M through 70CM on either my HT, HF radios or the AM or FM broadcast bands. The problem of most Ham power supplies is that while they are RF quite they are only current limited by the smoke that they emit just before failure. Failure can occur when the utility power returns after a power outage that discharged the battery enough to cause it to draw more power than the power supply can safely produce. Adding a fuse and a series diode will protect the power supply but will leave you with a discharged battery after the fuse blows. The SEC-1215UL charger is current limited and will start recharging the battery as soon as the utility power returns. The charger has internal fuses protecting the input and output but there is no ON/OFF switch. The Amp Meter is very useful and it will give an indication of the battery's state of charge. A fully charged AGM battery will draw very little float current. The DC charger output is floating in respect to the AC input and the Case ground to prevent any ground loops. The charger does not have a fan, is absolutely quite and the instructions detail a vertical mounting solution for cooling. No Battery cables are provided but it was easy to make custom cables for my application with the pin type lugs that were provided and some wire & connectors from Lowes. The Charger as shipped, operates from 120 VAC but can be configured for 230 VAC if desired. I plan to purchase, in the near future, a Samlex America Solar SEC-1230UL Battery charger for another project. The SEC-1230UL has the same features except it has a higher output and a cooling fan. The Samlex Solar SEC-1215UL SEC-UL Series 12V Battery Charger ships with an instruction manual filled with very useful information on how to set-up and operate the charger. The charger is a nice looking unit both inside and outside. I gave the unit 5 stars because it is a super replacement for the previous noncurrent limited power supply and the great technical support from Samlex. Update: 09-28-2018 I have added two 3" X 3/4" X 1/8" steel angle brackets to the end of the battery charger that the cables attach. This allows the charger to stand with the meter visible for easy reading. No holes were drilled as the angle brackets already had holes. Two #8 screws were used to attach the angle brackets to existing holes in the charger. The first time I used the charger was to recharge a fully discharged 100AH AGM battery and after several minutes @ 15 Amps the charger warms up quite a bit. The charger changed from boost voltage to float voltage at about 2 amps. If you have more than one fully discharged 100AH battery, it would be better to recharge each one separately. I am very pleased with the Samlex Model SEC-1215UL Battery Charger.

In other words, regardless of what the charger is doing can I say, select 6amps or some other number to charge batteries at a slower rate?** A: No. It uses a charging profile for the type of battery and mode selected (DIP switches). By mode I mean you can set it to be a power supply, battery charger, or combo power supply / battery charger. When in the last mode, it doesn't go into the boost phase (highest voltage) at all because it can't tell what current is going into the battery vs going into the load. If you have a constant load, you'll end up toasting your battery because it will sit at a high voltage for too long. I believe if you find the manual for one of these, it will describe the various charging profiles in more detail. I think it starts off with constant current for lead acid and then switches to constant voltage. But I don't think you can control the exact values. **Q: Would this be suitable for use on a fishing boat? Would an occasional sprinkle/splash of water or rain drops damage the unit?** A: The Samlex units are rock solid, and weather/water resistant. I have one installed on a 28' Boston Whaler Center Console and I have had no problems. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***R on 13 July 2018* This review is for a Samlex America Solar SEC-1215UL SEC-UL Series 12V Battery Charger that Ships from and sold by Amazon.com This is a well built Hi Quality Product and well worth the price.

I found this as a warehouse deal, which means it was discounted because it was slightly damaged. When received, I couldn't find damage anywhere except maybe on the packaging if I looked hard enough. Great way to save 20%. The product itself works fine. It comes with 4 uninsulated pin terminals fit 8 gauge wire for the output. You'll need a proper crimp tool for heavy gauge uninsulated terminals to use these. Finally, my recommendation is to print off a copy of the DIP settings table and tape it to the top for handy reference. If you change the DIP settings and get them wrong, bad stuff will happen. ## Frequently Bought Together - Samlex America Samlex Solar SEC-1250UL SEC-UL Series 12V Battery Charger,Black - Blue Sea Systems 7184 285 Series Circuit Breaker, Surface Mount, 60 Amp, 48V DC - Bay Marine Supply MRBF Terminal Fuse Block Kit (Fuse Included) – Single Stud 5/16" (M8) Compact Marine Rated Battery Fuse 250A --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/208400714-samlex-america-samlex-solar-sec-1250ul-sec-ul-series-12v](https://www.desertcart.it/products/208400714-samlex-america-samlex-solar-sec-1250ul-sec-ul-series-12v) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-12*
