DL321

DL321 is a MOSFET phase cut dimmer. The output to the load is 230V. It is powered with phase (L) and neutral (N) and can be controlled from one or more points by means of normally open buttons of any civil series.

The product is immersed in UL94 V-0 polyurethane resin, which gives the product flame retardant properties.

With DL321 it is possible to configure the minimum brightness, so as to be able to adapt it to each type of lamp and avoid flickering problems.

Memory mode can be activated.

The installation is built-in.

The device works in TRAILING EDGE mode.

Dimmer operation

Default operation (without memory)

Standard operation (factory setting) is without memory. For each short pulse, the dimmer acts like a normal ON-OFF switch. If the light is off, it will turn on reaching the maximum level and vice versa if it is on it will turn off. If, on the other hand, you intend to dim the light, the pulsed must be prolonged and always with the light on. Once you release the button, the light will stop at the desired point. With each prolonged pulse, the dimming "changes direction". In this mode, every time the light is turned off the dimmer will "lose memory" of the brightness level set.

The first diagram refers to the duration of the pulse (with time on the abscissa axis).

The narrower and more striped rectangles mean a short pulse, the wider ones a prolonged pulse.

The diagram below refers to the brightness of the lamp (brightness on the ordinate axis and time on the abscissa axis).

For each short pulse, the brightness always passes from the min to the max level and vice versa, without stopping at intermediate levels.

The first long push on the graph sets the brightness from the maximum to the desired intermediate level.

The second button "changes the direction of dimming" and in this case regrows the brightness up to the maximum level.

Operation with memory

To set the dimmer in memory mode, follow the instructions on the instruction sheet.Once the memory mode has been set, a preset brightness level can be memorized for each switch-on. To do this, simply dim the light to the desired brightness level, then, each time it is switched on, the dimmer will "remember" to switch on the lamp directly at the last brightness level set.

After a short press of the button, the light turns on at the maximum level.

Subsequently, the user gives a prolonged pulse, then going to dim the light and releasing the button at the desired brightness level.

This level is therefore the stored level.

Another short push from the user switches the light off, while the next one switches it on again at the last selected brightness level (memory function).

Minimum calibration

DL321 allows you to calibrate the minimum light, as each type of lamp may need a different minimum light, and this can also be useful to avoid "flickering" problems.

To calibrate the minimum light it is necessary to give a prolonged pulse until the light falls to the minimum.

Once the brightness has reached the minimum you have to keep holding the button down for about another 5 ".

At this point the brightness should begin to "fluctuate" (between 0 and 20%).

To set the new minimum, just release the button at the desired brightness level.

Frequent questions

Do you have any questions? We are here to help you.
  • The lamp flickers

    Check that the lamp is dimmable and of good quality.

  • A few minutes after switching on, the light goes out.

    DL321 is equipped with an overheating protection device, which turns off the light if the dimmer overheats.

  • Other operating problems

    Check that you have no stuck buttons.
