The DIM11 is a low voltage 12V or 24V PWM lamp and LED one-touch dimmer module controlled by a single external momentary switch.
The module operates from a 12V or 24V supply (9-32V operating range) and can control up to 10A (120W at 12V, or 240W at 24V) of LED, tungsten or halogen lighting
The unit connects to a single momentary switch which completely controls the dimmer operation: a brief press of the switch will toggle the lamp on or off, and a sustained press will cause the lamp brightness to ramp up or down for as long as the switch is held, repeating until the switch is released at the desired brightness level.
The Mode input controls the operating behaviour of the unit and should be connected during installation. Leaving the Mode terminal unconnected, when the lamp is turned on by a brief press of the control switch it will operate at full brightness. The brightness level can then be changed by a sustained press of the control switch. The lamp will revert to full brightness when the lamp is turned off and back on again.
With the Mode input connected to the +Supply terminal, when the lamp is turned on the previously stored brightness level is retrieved. The level can then be adjusted with a sustained press of the control switch. When the lamp is turned off, or when power to the module is lost, the current brightness setting is stored for retrieval next time.
Regardless of the Mode input, the last-saved brightness level and on/off state are recalled when power to the unit is first applied. This ensures the current brightness level is not lost when power is removed, and any power glitches to the unit will not cause the lamp to suddenly change brightness or state.
In addition, the brightness ramp direction swaps between switch presses - that is, if the brightness is currently increasing, the next sustained press of the control switch will cause the brightness to decrease. This allows the user to adjust the brightness accurately and quickly.
The Control pushbutton can be any momentary pushbutton switch, or relay contact. The unit is supplied without a switch, and a selection of pushbuttons is available separately from Abeltronics.
