Tips for the planning of dimmers for LED lamps

Selecting lamps
Ensure that the LED lamps are dimmable.
Preferably only install lamps of the same manufacturer and from the same batch (same date of manufacture) in a system.

Take account of installation position
Plan for the maximum nominal power of the dimmers to be reduced depending on the planned installation position and the expected ambient temperature.

Configure the operating mode
Leave the operating mode initially configured on "Universal" and test the system. If there are problems: configure and test the LED-trailing edge phase control operating mode. If there are still problems: configure and test LED-leading edge phase control operating mode.
For the highest possible connected load: select LED trailing edge phase control. For the largest possible dimming range: select LED leading edge phase control.

For complex installations
The dimming of larger (LED) loads can be realised with power boosters (for rail mounting).
Check whether a DALI system represents a viable alternative.
