Samlex America Samlex Solar SEC-1250UL SEC-UL Series 12V Battery Charger,Black

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 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.

This device is charging your vehicle and your battery. Best to get the better one. The unit is well constructed, comes with gauges, nice heat sink and quality connections.

When I first installed it in my van it worked great. Only used it to charge van house battery when at a campground with power. Lasted less than 2 years and now overheats whenever it is plugged in.

The Samlex America (SEC1230UL) 30 Amp Battery Charger charges my two 225AH Trogan T105 golf cart batteries in about 4 hours at the three different stages perfectly. Worth every penny to know my T105's are being charged properly to ensure they'll be able to deliver their long service life. Don't skimp on a true 3 stage automatic battery charger. It's nice to be able to throw it on the batteries and forget it. Many charger produce dirty power that can affect attached electronics, not this charger. My set up charges 2 isolated house batteries in a boat. When the charger is on and the stereo is used no noise from the charger unlike others.

Extremely well made and easy to use product. Does exactly what it is designed to do very well. Very reliable charger and clean 12V power supply for all your DC loads. Highly recommend! Let me know if you have any questions about this product. Shane Cauley, Owner Shane's Vans.

I have tests under way on #2 now will up date in 1 month.

This charger matched my needs and has performed exactly as specified, but equally noteworthy is that Tech Support has been outstanding. I've had two occasions to contact them (NOT because of any defect or problem with the charger) and the response has been fast and extremely helpful. I also have to mention Samlex documentation goes well beyond the "minimum requirements" and provides a wealth of very helpful background information. [Update: Nov 2018] Decided I needed reduce the rating by a star because the 30 amp charger does NOT have a battery temperature sensor or the means to connect one. I accidentally completely discharged a 105AH deep cycle battery and this charger on that small a battery produced a thermal runaway condition that, fortunately, I caught before any significant damage was done. The charger does an excellent job of charging, but a battery temperature sensor would be a most welcome addition when charging a very depleted smaller battery bank.

This device is not repairable if it fails. Technicians state that no parts are available. Samlex does not provide a repair facility.

PRODUCTO ESPECTACULAR FUNCIONA SENSACIONAL Y SU CALIDAD ES MUY ELEVADA.. VALE CADA PESO.

Plugged it in, 6V batteries went through the 2 stages & now it's in maintenance mode. Happy so far.

as described and EXCELLENT customer service I called the 3 times always nice
