Triac dimmable led driver

They are semiconductor devices, similar to a diode. TRIAC is often used as a means of light dimming in domestic lighting applications, and can even serve as a power control in motors. This means it can work to suit everyday lighting-control needs.

TRIAC circuits are used for more than just domestic lighting though, they are also utilised when controlling fans and small motors, and also in other AC switching and control applications. If you are looking for a multipurpose control, we are sure you will find TRIAC to be a very useful protocol. Triggering the circuit allows conduction of electricity until the current falls below the intended threshold.

Using phase control, a TRIAC can control the percentage of current that flows through a circuit load. A TRIAC controller acts as a high-speed switch, and is used in controlling the amount of electrical energy that goes through a bulb. It usually has a trigger which dictates when electricity can be conducted and reduces the voltage to avoid the energy being supplied to go overboard.

It is a sensitive gate with a V blocking voltage. This is a dimmable voltage LED driver, designed to operate with a triac dimmer switch. It is available with an aluminium casing. This type of power supply is a great choice for straightforward control of tape lights and LED fixtures, as well as under-cabinet lights and other applications. Yes, it is! The most common dimmer is the standard forward phase dimmer: it comprises a TRIAC and a resistance circuit.

Resistance is controlled by a potentiometer, and the RC time then controls the amount of delay created before a TRIAC turns on which is also the firing angle. A standard switching converter is used in regulating the output with no limits on the input voltage. In this case, the phase-chopped waveform provided by the phase dimmer is decoded first; the decoded info is used in controlling the reference for output regulation. So it is important to ensure that your phase-cut dimmable LED driver is compatible with the dimmer switch you will be using before you can make any purchase.

You wire them in inverse parallel, you can then control them using a one-gate terminal. Current is then transmitted in whichever direction you choose, whether to MT1 or MT2 terminals which is then used in controlling AC power. Positive or even negative gate current is used as a trigger regardless of the polarity of the MT2 which leads to four trigger modes. Get Best Quote. I am Interested. Looking for Led Light Drivers?
