WHAT IS PHASE DIMMING?
- There are two types of Phase Dimming: Leading Edge Dimming and Trailing Edge Dimming
- Leading Edge dimming is sometimes called Forward Phase or TRIAC dimming
- Trailing Edge dimming is sometimes called Reverse Phase or Electronic Low Voltage Dimming.
- There is a massive installed base of phase dimmers which is why they are so popular.
- There are no additional wires on a Phase Dimming driver. The dimmer is wired in line with the output of the driver.
- Phase dimming is only available in 120V input
WHAT IS 0-10V DIMMING?
- This dimming type is used in most new construction and commercial applications.
- There are extra wires (usually grey and purple) on the driver that hook up to the 0-10V dimmer.
- 9V is the maximum light level and 1V is the minimum light level.
- 0-10V dimming is available in universal 120V-277V input.
