How many kinds of Dimming type?
22 Dec, 2020
If you are not familiar with the dimming types that are compatible with LEDs: following details will definitely help you. Mains / phase cut dimming As the power of phase cut dimming led driver is reduced in some way therefore less power reach into LED light and becomes dims. This dimming led power supply uses standard L, N，G wires, easy to install and...

Eight tips to improve the efficiency of LED power supply
05 Jan, 2021
1. The main current loop PCB should be as short as possible. LAYPCB experience, and layout, this is nothing, the quick way is to look at the works of big factories. 2. Optimize the design of 300w LED transformer parameters to reduce eddy current loss caused by ringing. This is more difficult. First, you must master the basic knowledge...

The Lifetime and Reliability of led driver vs power supply
01 Feb, 2021
The LED is a device that includes a single PN junction and has conductivity on one side. The LED will only emit light when current is applied forward. Because LED lights work at low voltage, the led screen power supply needs to properly manage the load and effectively provide the required low voltage power to the LED. The street light power supply rectifies commercial AC power into DC po...

Choose LED Power Supply or power adapter?
24 Feb, 2021
Both LED power supply and power adapter are widely used for driving LED strip light. How to choose the suitable one? Depend on the project scale and installation way. Many users intend to find a led strip driver for 5m or 10m LED strips. Here we have to explain that it is not the LED strip length that determines what led power supply driver to choose, however is the total wattage of the LED...

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 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...

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...
