Universal dimming switch. Power MOSFET up to 400W. Automatic lamp detection. Stand-by loss only 0.1 watt. Minimum brightness or dimming speed can be set. With children's room and snooze switch. For panel mounting. 45mm long, 45mm wide, 18mm deep. Universal dimming switch for lamps up to 400W, depending on the ventilation conditions. Dimmable energy saving lamps ESL and dimmable 230V-LED-lamps additionally dependant on the lamp electronics. Switching in zero crossing with soft-on and soft-off for lamp protection. Control voltage, supply voltage and switching voltage 230V. No minimum load required. Short control commands switch on / off, permanent control changes the brightness up to the maximum value. An interruption of the control changes the dimming direction. The set brightness level remains stored when the device is switched off (memory). In the event of a power failure, the switching position and the brightness level are saved and, if necessary, switched on when the supply voltage returns. Automatic electronic overload protection and over-temperature switch-off. The upper %Lamp/dim-speed rotary switch can be used to set either the dimming speed or the minimum brightness (fully dimmed). The dimming speed also changes the duration of soft-on and soft-off. The lower rotary switch determines during operation whether the automatic lamp detection should work or special Comfort settings: Auto allows dimming of all types of lamps. EC1 is a comfort setting for energy saving lamps, which must be switched on with an increased voltage due to the design, so that these dimmed also reliably switch on again when cold. EC2 is a comfort setting for energy saving lamps, which cannot be switched on again due to the dimmed design. Memory is therefore turned off in this position. LC1 is a comfort position for LED lamps, which cannot be dimmed sufficiently on AUTO (phase section) due to the design and must therefore be forced to phase angle. LC2 and LC3 are Comfort positions for LED lamps such as LC1, but with other dimming curves. Do not use inductive (wound) transformers in positions EC1, EC2, LC1, LC2 and LC3. In addition, the maximum number of dimmable LED lamps may be lower due to design than IN THE AUTO position. With children's room circuit: When switched on with longer button actuation, the light is switched on at the lowest brightness after approx. 1 second and dimmed up slowly as long as the button is still pressed, without changing the last brightness level saved. With snooze function: By a double pulse, the lighting is dimmed from the current dimming position to the minimum brightness and switched off. The max. dimming time of 60 minutes depends on the current dimming position and the set minimum brightness and can therefore be shortened accordingly. By means of short buttons, you can switch off at any time during the dimming process. A long button during the dimming process dims up and ends the snooze function. L-loads (inductive loads, e.g. wound transformers) and C-loads (capacitive loads, e.g. electronic transformers and LED lamps) must not be mixed. R-loads (resistive loads, e.g. 230V incandescent and halogen lamps) can be mixed in as desired.This text is machine translated.
