What are ELV Dimmers
ELV dimmers are electronic low-voltage dimmers that are designed to work with light fixtures that use electronic transformers. These dimmers work differently than traditional or multi-location dimmers, which use rheostats to adjust the voltage level. ELV dimmers use pulse-width modulation (PWM) to control the power delivered to the light fixture, resulting in a smoother and more precise dimming experience.
How ELV Dimmers Work
ELV dimmers use a microprocessor to control the voltage delivered to the light fixture. The microprocessor sends a series of pulses to the electronic transformer, which then converts the pulses into a constant voltage output. The frequency of the pulses determines the amount of power delivered to the light fixture.
An ELV dimmer works like this: the electrical load is turned off at the end, or trailing edge, of the Alternating Current (AC) waveform. 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. Resistive and capacitive loads are compatible with an ELV dimmer precisely because of its trailing-edge functionality. Meanwhile, a leading edge dimmer only has compatibility with loads that are either inductive or resistive.
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. 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.
Advantages of ELV Dimmers
ELV dimmers offer several advantages over traditional rheostat dimmers. These advantages include:
- Smooth and precise dimming control
- Less flicker and noise
- Improved energy efficiency
- Longer bulb life
Compatibility
ELV dimmers are designed to work with electronic transformers, which are commonly used in LED and halogen lighting systems. These dimmers may not be compatible with magnetic transformers or incandescent lighting systems. Before purchasing an ELV dimmer, it is important to check the compatibility with the lighting system being used.
Installation
ELV dimmers can be installed in a similar manner to traditional dimmers. However, it is important to follow the manufacturer’s instructions and consult a licensed electrician if necessary. ELV dimmers may require a neutral wire and may not be compatible with certain types of switch boxes.
Things to Consider when Buying ELV Dimmers
When you’re purchasing an LED system of illumination, it is integral that you get the right kind of dimming technology. The advantage of the LED is its ability to conserve energy while providing trustworthy illumination for a longer period of time than is commonly associated with filament bulbs or fluorescent lighting. LED technology is taking off because it can provide the same amount of light from a lowered quotient of energy. But since it does initially cost more than traditional lighting motifs, if you don’t have the right kind of dimmer, you’re going to waste money. Granted, some LED applications require no dimmer whatsoever; but in a good number of them, being able to dim the light is desired.
Conclusion
ELV dimmers are an excellent choice for those who want a smooth and precise dimming experience with their electronic transformer-based lighting systems. They offer several advantages over traditional rheostat dimmers, including improved energy efficiency and longer bulb life. When purchasing an ELV dimmer, it is important to check compatibility and follow installation instructions carefully.
