What’s the difference between leading edge, trailing edge, 0-10, Triac, etc.?

- Aug 27, 2020-

Leading edge (also known as Forward Phase/MLV ) dimming refers to the low cost triac type dimmers that phase cut the leading edge of the AC sinewave. 
Trailing edge (also known as Reverse Phase /ELV ) dimming refers to the higher end Mosfet based dimmers, which phase cut the trailing edge of the sinewave.

Our dimmable drivers can operate with either type dimmer.

0-10V dimming is a low voltage, secondary side control method, where a DC voltage level is applied to a driver (or dimmer module) to control the output level, either through PWM or DC voltage/current. This 0-10V signal can come from a commercial low voltage dimmer, such as a Lutron dimmer control, or from an adjustable DC supply, which can be adjusted from 0-10V DC, or even a computer controlled system, which uses a A/D converter output that generates the 0-10V signal level.
