I need a replacement power supply ac/dc adapter for LED lighting. Model number on current adapter is JY15-120-100-UD Input: 100-240V ~50/60Hz 0.4A Output: 12V 1000mA Can you please send recommendation. My lights turn on and then begin to flicker after 20 minutes and power supply seems to be overheating. Do you think that my power supply is going out? Thanks for your assistance. Jorge
Hi Jorge, If your LED lights are flickering, it is most likely a power supply issue, but before you start checking for power supply issues, make sure that the wiring and connections are ok.. Make sure there are no loose connections, all screws holding wires are tight, and all soldering is solid. If you confirm all this, and the lights are still flickering, first see if the power supply is overheating.. If it is getting really hot, it might be overloaded.. Make sure you are not running more lights than the power adapter can handle. If it is super hot, it is either defective, or not powerful enough for your load. The next thing is to check the Voltage of the output. With a voltmeter, see if the power supply is putting out a steady 12 Volts or if it is flickering.. If it is varying by more than 1V up or down, the power supply is defective. Replace the power supply.
AC Adapter input 100-240v, output 12V- 3amp needs replacement for our Lorex monitoring system Problem we are having is that in the possible replacements found, the circular plug although it seems to be same size outside diameter, is actually 1/8 smaller on the inside diameter and will not fit. How can we find apaptor with plug that fits. Any help appreciated
Hi M**** The majority of 12V 3A power supplies use a 5.5mm x 2.5mm connector. I would recommend trying that one because it is the standard. A small percentage of 12V Power Supplies use a 2.1mm interior barrel instead of 5.5mm. If the barrel is a little smaller, the 2.1mm should work.. Also, in most cases, a 2.5mm barrel will work with the 2.1mm plug anyways.. It will just be a little loose... The only other possibility will be to buy and a use a measurement gauge.. it is something that looks like a ruler, and has 2 points that slide apart and together to give an accurate measure of the power supply connector.
I'm trying to power a belkin tunecast 2 fm transmtter. The input hole is very small which adapter do i need? Thanks in advance for your help.
Most power supplies that are 12V come in one of two types of connectors. The vast majority of 12V power supplies between 1A and 5A (Amps) use the standard 5.5mm x 2.5mm connector. This covers over 95% of all power supplies... There is a small minority that use a 5.5m x 2.1mm tip.. These are usually in the 1A to 2A range... Please note that in many of the 2.1mm connector units, the 2.5 mm connector will still work as they are so close in size.
This article deals with the special considerations you must make when you are choosing a power supply for a a DC motor. These special considerations require an understading of continous vs peak draw, and how they effect any specific 12V Power Supply.
