Main types of power supply

There are 2 main types of power supply, using low voltage DC input power (generally 5-48VDC) and using high voltage AC input power (generally 100-305VAC). Those that use high-voltage AC power are called AC LED drivers. As per our experience, most of applications using low voltage DC input LED driver. Even if your input is high voltage, you also can add ...

How does LED to dimming?

As a constant current source, LED lamps can be dimmed naturally. The current flowing through the LEDs beads determines the light output, and their brightness can be adjusted very easily by adjusting the current through the layer of semiconductor material attached to the substrate. Dimming ways are divided into two types: one is constant voltage dimming, and the other is constant current dimm...

What is the meaning of the UL class 2 led driver?

UL Class 2 led driver comply with standard UL1310, meaning output is considered safe to contact and no major safety protection is required at the LED / luminaire level. There is no risk of fire or electric shock. These switching power supply driver operate using less than 60 volts (dry) and 30 volts (wet), less than 5 amps, and less than 100 watts. Although safer, these lim...

Does the triac/phase cut dimming led driver from Smarts Electronics have PWM output ?

Answer: Yes, there are three series of triac dimming led driver from Smarts, they are called as version 1.0, version 2.0 and version 3. Here is the general informations as below. Version 1.0 don’t have PWM output function. This series is the early type led driver which we developed around 2015. They are 3 year warranty and 12vdc 24vdc led driver design output, 100-130vac or 170-265vac. As the time...

Constant Current & Constant Voltage

As we all know, there are two kinds of led driver, constant voltage and constant current. But what kind of LED driver do I choose it ? How can we distinguish between these two? 1. What is constant current led driver? Constant current LED drivers are designed for a designated range of output voltages and a fixed output current. It is can be used fo...

Compatibility between triac dimming power supply and dimmer

Well known that triac dimming has a leading edge cut wave and a trailing edge cut wave, but more than 90% of the triac dimming power supply is uncompatible with the mainstream led driver dimmer on the market, nodes flicker or continuous flashing when the brightness is adjusted to less than 15% or less. Whether you are using leading edge or trailing edge control, it can be r...
