LED dimming power supply generally has Silicon controlled dimming, 0-10V dimming, PWM dimming, resistance dimming, DALI dimming, DMX512 dimming and so on.(1) Silicon controlled dimming The silicon controlled dimmer is a high-power semiconductor device with four layers of three PN junction. ...
When the device emits any harmonics and distorts the mains supply, it is called harmonic current emission. It is associated with switch mode power converters and other non-linear loads such as motor, transformer, and lamp dimmers. Harmonics from the device(Image:Science Direct) Electromagnetic Su...

A residual current circuit breaker (RCCB) is an electrical safety device that detects and interrupts an electrical circuit when there is a leakage current to the ground. It protects people and equipment from electric shocks, fires, and other hazards caus
The “S” stands for switch box or splitter. The main purpose of this part is to split the incoming supply from the generator into two. One feed goes to the welder and the other to a selection of “dumpable loads” which are switched off while welding is in progress. ...
When the switch is closed, most of the current flows through the coil, providing a low-resistance path. Therefore, we expect the lamp to glow dimly. But due to inductor behavior in the circuit, when we close the switch, the lamp glows brightly and then gets dimmer and when we open the...
As a dimmer it raises and lowers the amount of electrical energy flowing out to the LEDs. There are two mains ways that a driver does this - pulse width modulation (PWM) or amplitude modulation (AM) - and these are discussed below. However, if a driver uses PWM or AM is generally of...
What are the tradeoffs between linear vs switch mode LED drivers? Linear drivers offer simplicity with just an adjustable linear transistor element but waste significant power dropping excess voltage as heat. Switching methods use inductive energy storage for efficient conversion but require fast PWM con...
Flicker is the repeated and frequent variation in the output of a light source over time. Some authors speak of the “modulation” of the light output, others speak of the light output rising and falling or getting brighter and dimmer, but these are all different ways to describe the same ...
