# What is a 1-10V dimmer?

## What is a 1-10V dimmer?

Explaining 1-10V dimming 1-10V dimming uses a controlled DC voltage signal to vary the brightness of the fitting(s). 1 is the lowest level, typically 10% of light output, and 10 is the brightest, at 100% of the light output. There is a linear pattern on light output in between 1 and 10V, so 5 would be circa 50%.

### How does 10V dimmer work?

0-10V dimming is a lighting control method that – on direct current voltage (DC) between 0 and 10 volts – can produce light at varying intensity levels. 0-10V dimming is the simplest control system for lighting, providing smooth operation and dimming down to 10%, 1%, and even 0.1% light level.

What is the difference between 0-10V and 1-10V dimming?

The main difference between 0-10V and 1-10V is the direction of the current between dimmer and driver. 0-10V is a current source system, which means that the dimmer provides the power for the 0-10V signals – a mains connection to the dimmer is necessary. 1-10V is a current sink system.

What does phase dimming mean?

Phase dimming works by reducing the amount of primary, 240v power that feeds into an LED driver or a traditional light bulb. It is known as ‘Phase’ or ‘Phase-Cut’ because this type of dimming reduces the 240v power at a particular phase of the sine wave.

## What is a 1-10V driver?

1-10V Dimming (analogue) These dimmer switches are similar to DALI but send an extra low voltage analogue control signal (1-10V) to a driver down separate wires to the mains supply. They do not directly control the energy passed to the driver. Lamps are never directly 1-10V dimmable.

### What does 10V mean?

0-10V dimming applies a direct current voltage (DC) between 0 and 10 Volts to produce light at varying intensity levels. At 10V, the lights controlled by the dimmer are at 100% brightness. At 1V, the lights are at 10% measured brightness, which may actually be perceived as 32% brightness.

Can you use a 0-10V dimmer on a 1 10V driver?

If a 1-10V dimmer is used with a 0-10V driver, the minimum level achieved will not match the minimum level available on driver. On the flip side, when a 0-10V dimmer is used with a 1-10V driver, strobing or other low-end performance issues will likely happen.

What is a DALI dimmer?

DALI (Digital Addressable Lighting Interface) These dimmer switches use a digital protocol to send a dimming control signal to a driver down separate wires to the mains supply. They do not directly control the energy passed to the driver. Lamps are never (directly) DALI dimmable.

## What is TRIAC dimming vs 0-10V?

0-10V light dimming also known as the 0-10V signal dimming, is an analog dimmer that distinguishes itself from the triac power supply by adding two additional 0 -10 V interfaces (+10 V and-10 V) to the 0-10 V power supply.

### What are the three primary types of dimming?

What are the different methods used for dimming?

• Dimming of electrical potential (decrease in power): phase control.
• Dimming of control signal (analogue): 0-10V, 1-10V.
• Dimming of control signal (digital): DALI.

What does mains dimmable mean?

Mains dimming works by chopping up the electrical signal from the mains. It does this by switching the electric current on and off several times a second. The result of this rapid switching is that less power is available to the light as the power is off for part of each second.

What does switch dim mean?

Switch Dim/Touch Dim The switch controls the switching on and off of the luminaire, and also the dimming. When the switch is pressed and held it will dim down. Another press and hold will dim back up. A momentary push will switch off and also bring back on.

## What are the two types of dimmers?

Most dimmers fall into these four bulb type categories:

• Incandescent and halogen bulbs.
• Dimmable compact fluorescent light bulbs.
• Magnetic Low Frequency (MLV)
• Electronic Low Frequency (ELV)

### What is triac dimming vs 0-10V?

What is dimming wire?

The dimming signal, which is connected to the source (driver) typically has a purple wire that represents +10 volts and a gray wire representing the signal. When both wires are not touching, the dimming control output will be 10 volts, or 100%. When they are touching, the dimming control output will be 0 volts.

How does a low voltage dimmer work?

ELV dimmers are also called simply “electronic dimmers”, as well as “trailing edge dimmers”. These names come from the way in which this dimmer transitions your LED’s luminosity. An ELV dimmer works like this: the electrical load is turned off at the end, or trailing edge, of the Alternating Current (AC) waveform.
