ELV dimmers are often used with LED drivers because they have a great track record for improving an LED’s ability to conserve energy while providing luminosity in a functional, sustainable way.Īnother advantage of the ELV dimmer is that it is not going to be party to a massive voltage influx allowing in too much current too quickly. While trailing-edge dimmers are more complicated than other options, their increased compatible nature coupled with their energy-saving design makes them ideal for LED technology, making ELV dimmers in many cases the dimmers of choice. Meanwhile, a leading edge dimmer only has compatibility with loads that are either inductive or resistive. Resistive and capacitive loads are compatible with an ELV dimmer precisely because of its trailing-edge functionality. Power to the load can be controlled, and this is done by a variance being applied to the ratio of on/off time, called the “duty cycle”, which exists in conjunction to the voltage as related to the load. These names come from the way in which this dimmer transitions your LED’s luminosity.Īn ELV dimmer works like this: the electrical load is turned off at the end, or trailing edge, of the Alternating Current (AC) waveform. ELV dimmers are also called simply “electronic dimmers”, as well as “trailing edge dimmers”. An ELV dimmer is known by a number of names.
