![]() An ELV dimmer works like this: the electrical load is turned off at the end, or trailing edge, of the Alternating Current (AC) waveform. They require the low voltage to control the brightness, instead of dimming the AC voltage that turns the fixture on and off. ELV dimmers are also called simply “ electronic dimmers”, as well as “trailing edge dimmers”. An analog dimmer, also referred to as 0-10 volt dimmer, is mainly used when dimming larger led fixtures such as troffers and panels. Screw terminal connectors allow for quick and easy connection for power input and output. It has an easy to use control knob for variable brightness levels. An ELV dimmer is known by a number of names. Low voltage mini LED dimmer can dim 12 or 24VDC LED Flex strips or LED bars from 0-100 using Pulse Width Modulation (PWM). #Low voltage dimmer for led lights drivers#LEDs can be a little more complex than this and often drivers will need to be more closely matched to their light source. They are also more budget friendly but are noisy and only last 5-6 years.ĮLV stands for Electronic Low Voltage. Most low voltage transformers for lighting will convert a mains voltage of 220/240 volts AC to 12 volts AC as this is often the required standard for low voltage lighting. The electronic transformers are lighter and smaller than their magnetic counterparts. #Low voltage dimmer for led lights professional#Modern professional dimmers are generally controlled by a digital control system like DMX or DALI.Ĭorrespondingly, what is the difference between magnetic and electronic transformers?Įlectronic Transformers The higher the frequency of the voltage, the smaller the transformer needs to be to provide the required output voltage. By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output. Magnetic Low Voltage dimmers are specifically designed to prevent DC voltage from being applied to the transformer.įurthermore, what is an electronic dimmer? Dimmers are devices connected to a light fixture and used to lower the brightness of light. Regular incandescent dimmers often contain a small amount of DC voltage, which is harmless to a regular incandescent load but may damage magnetic transformers. Similarly, what is a magnetic low voltage dimmer? Low voltage mini LED dimmer can dim 12VDC or 24VDC LED Flex strips or LED bars from 0-100 using Pulse Width Modulation (PWM). ![]() Dimmers for magnetic low- voltage transformers use a technology known as standard phase control or “leading edge,” whereas dimmers for electronic low- voltage transformers use reverse phase control or “trailing edge.” Standard phase control is for use with either inductive (MLV transformers, fans) or resistive ( ![]()
