What is the difference between Magnetic dimmable transformer and Smarts’s dimmable power supply?
2020-09-14

Magnetic dimmable transformer and Smarts’s dimmable power supply are very common to see in the market, however do you know their difference? Let us together to make a comparison betwen both of them.

dimmable power supply

1.circuit structure & operating principle
Magnetic dimmable transformer: cicuit solution designing is simply, lack of output control & feedback circuit,and no ripple circuit which makes the output ripple very high.
Smarts’s dimmable LED power supply has the completed circuit designing solution which combile the EMI circuit, output voltage & current controlling circuit ,output feedback circuit and fixed ripple circuit together, which makes the ripple very small. 
2.output voltage wave shape
Magnetic dimmable transformer work with AC output, peak value =33.6V. When load it with 24V LED tape light, Peak voltage value will passover the LED rated voltage, which will shorten LED's life-span.
Smarts’s dimmable LED driver with DC output, their peak voltage values are 1.6V & 0.8V, it will no affect the LED's life- span.

3.Stability of output voltage
If the LED working voltage is 24V and the transformer is 100% loaded, the output voltage is only 22V exactly, the LED light is no brightness enough. When loading less than 20%, LED light become very brightness.When the transformer output voltage higher than 25.2V, it will burn down the LED.
When load Smarts’s led power supply from 0 to 100%, output voltage changing rate lower than 0.1%, the LED light 
working stablely in their working voltage range.
4.The influence of input voltage to LED lights
When the input voltage of Magnetic transformer changing in 110-130V, the output voltage will be changed relatedly.
when the input voltage are changed in the rated 110~130VAC, the output voltage of Smarts’s drivers vary very small (lower than 0.1%), the LED brightness will almost no be changed.
5.Overload protection
Magnetic dimmable transformer without overload protection
Overload protection when Smarts’s led power supply load<120%.

From what has been discussed above, Smarts’s electronics dimmable LED driver is the best choice for LED lights.
