- Suitable for lamps up to 800 W, including dimmable energy saving lamps (ESL) and dimmable 230 V LED lamps, dependent on lamp electronics and dimming technology.
- Supports up to 3600 W with capacity enhancers LUD12-230V at terminals X1 and X2.
- Zero passage switching with soft start and soft OFF to protect lamps.
- Universal control voltage input: 8 to 230 V UC, electrically isolated.
- No minimum load required.
- Alternative PWM control: 10-24 V DC at PWM and GND connections.
- Brightness level is stored after switching off.
- Switching position and brightness level are stored in case of power failure.
- Automatic electronic overload protection and over-temperature switch-off.
Rotary Switch Operation
The dimmer features three rotary switches:
- Upper % rotary switch: Adjusts maximum brightness (fully dimmed up).
- Middle % rotary switch: Sets minimum brightness (fully dimmed down).
- Lower rotary switch: Sets the operating mode.
Operating Modes:
- ON: Permanent ON at maximum brightness.
- Pos. 1 (AUTO): Allows dimming of all lamp types. Switch on/off via device pushbutton or pushbutton connected to +A1/-A2. Dimming via rotary knob.
- Pos. 2 (Comfort): For dimmable 230 V LED lamps that cannot be dimmed sufficiently on AUTO (phase cut-off). Forced phase control. Switch on/off via device pushbutton or pushbutton connected to +A1/-A2. Dimming via rotary knob.
- Pos. 3 (Comfort): For energy saving lamps requiring higher voltage for cold start. Switch on/off via device pushbutton or pushbutton connected to +A1/-A2. Dimming via rotary knob.
- Pos. 4 (AUTO): Allows dimming of all lamp types. Switch on/off via switch connected to +A1/-A2. Dimming via rotary knob.
- Pos. 5 (Comfort): For dimmable 230 V LED lamps that cannot be dimmed sufficiently on AUTO (phase cut-off). Forced phase control. Switch on/off via switch connected to +A1/-A2. Dimming via rotary knob.
- Pos. 6 (Comfort): For energy saving lamps requiring higher voltage for cold start. Switch on/off via switch connected to +A1/-A2. Dimming via rotary knob.
- Pos. 7 (AUTO): Allows dimming of all lamp types. Switch on/off and dimming with PWM activation.
- Pos. 8 (Comfort): For dimmable 230 V LED lamps that cannot be dimmed sufficiently on AUTO (phase cut-off). Forced phase control. Switch on/off and dimming with PWM activation.
- OFF: Permanent OFF.
? The LED under the upper rotary switch lights up when the lamp is switched on.
ℹ️ In positions 2, 3, 5, 6, and 8, no inductive (wound) transformers should be used.
Typical Connection Diagram
The diagram illustrates a typical connection for the universal dimmer switch. It shows the input terminals L(+) and N(-) for an 8-230V UC universal control voltage. The main power line (L) connects through a switch to the dimmer's L terminal. The main neutral line (N) connects to the dimmer's N terminal. A pushbutton can be connected to terminals +A1/-A2 for switching on/off. The dimmer also has terminals for PWM control (PWM and GND). The output terminals (L and N) connect to the load (light bulb). The diagram also shows internal representations of the dimmer's components and connections.

Notes
- 1) Applies to lamps of max. 150 W.
- 2) Per dimmer, it is only allowed to use max. 2 inductive (wound) transformers of the same type. Furthermore, no-load operation on the secondary part is not permitted. The dimmer might be destroyed. Therefore, do not permit load breaking on the secondary part. Operation in parallel of inductive (wound) and capacitive (electronic) transformers is not permitted!
- 3) When calculating the load, a loss of 20% for inductive (wound) transformers and a loss of 5% for capacitive (electronic) transformers must be considered in addition to the lamp load.
- 4) Affects the max. switching capacity.
- 5) Usually applies for dimmable energy saving lamps and dimmable 230 V LED lamps. Due to differences in the lamps' electronics, there may be limited dimming range, switch on/off problems dependent on the manufacturer, and a restriction on the maximum number of lamps; especially if the connected load is very low (for 5 W-LEDs). The comfort positions optimize the dimming range, which, however, only gives a maximum power up to 100 W. No inductive (wound) transformers may be dimmed in these comfort positions.
- 6) At a load of more than 400 W, ventilation clearance of ½ module to adjacent devices must be maintained.
