What is the connection way between LED and LED drive power matching
06 May, 2021
We already know very clearly that there are only two ways to drive the LED: Constant current type: the current does not change and the voltage changes within a certain range (varies with the load) Constant voltage: constant voltage and current changes within a certain range (varies with load) There are three ways to cooperate with LED lights: series and parallel. In Series: The LED driver i...

Do you have 12v DMX512 dimmable led driver?
21 May, 2021
Yeah, we have 12V and 24V DMX 512 dimmable led driver, wattages from 30w to 300w dimmable led driver. We are in the progress of applying CE UL certificate, they maybe complated around mid of April, hopeful. Its input voltage range is 110-277Vac, it has different channels to be chosen, 1CH, 2CH, 3CH, 4CH or 5CH. With NFC (Near Field Communication) function, read and write DMX512. Adjust output volt...

The importance of electromagnetic compatibility of switching power adapter
21 Apr, 2021
The electromagnetic compatibility (EMC) of the switching power supply means that the switching dc power supply, power adapter or power transformer does not reduce its performance indicators due to electromagnetic interference under the specified electromagnetic environment level, and the electromagnetic radiation generated by them is not greater than the specified limit voltage. It does not affect...

What quality problems do ac dc led power supply generally have?
12 Apr, 2021
* Incomplete or irregular product marking The mark should contain important information that guides the user in the correct installation and use. Correctly marking the product's mark is one of the basic measures to ensure the user's personal and property safety. The mark must be durable and eye-catching. After normal use, the mark should not fall off and the content should be clean and readable. A...

Advantages of switching power supply
07 Apr, 2021
At present, LEDs are driven by DC, so you need a led drivers for lighting that converts AC mains power into a suitable DC power for LEDs. Then, when selecting and designing led drivers for lighting, the following points should be considered: 1.High reliability Especially like the driving power of LED street lights, installed at high altitude, it is inconvenient to maintain, and the mai...

What is the difference between 0-10V dimming, 1-10V dimming and 10v PWM (Pulse Width Modulation) signal dimming in 0-10v dimmable drivers?
29 Mar, 2021
Smarts Offer ce ETL UL 0-10v dimming driver in the market, they are dim by 0/1-10v , 10V PWM signal and resistance, we called 3 in 1 dimmable drivers. They are wattage from 20w to 200w dimmable driver, 12v dc and 24vdc range, then what is the difference in each dimming mode? 0/1-10V dimming: the dimme is 1-10V range: when the resistance dimmer is adjusted to the minimum 1V, the current...

Advantages of outdoor power supply 24v
15 Mar, 2021
1) Low internal power loss, high conversion efficiency The outdoor power supply 24v of Smarts can reach the megahertz level. The power loss on the switching power tube is reduced, the inductance of the energy storage inductor is reduced, and the energy storage power is increased. Therefore, the conversion efficiency of the entire outdoor power supply 24v can be greatly improved, and its conve...

What is a 12V dimmable driver?
09 Mar, 2021
Regularly 12v constant voltage led driver is not designed for dimmer switches, and perform unpredictably when dimmed. At best, you might have some measure of dimming control with inconsistent dimming or flickering, at worst, your lights might not work at all. The solution is a power supply designed for use with a dimmer switch : a dimmable driver. 12V dimmable drivers offer superior dimming a...
