Universal dimmer switch. Power MOSFET up to 400W. Automatic lamp detection. Stand-by loss only 0.1 Watt. Minimum or maximum brightness and dimming speed adjustable. With nursery and snooze circuit. Modular device for mounting on DIN-EN 60715 TH35 rail. 1 division unit = 18mm wide, 58mm deep. Universal dimmer switch for lamps up to 400W, depending on ventilation conditions. Dimmable 230V LED lamps and dimmable energy-saving lamps ESL additionally depending on lamp electronics and dimming type. Zero-crossing switching with soft ON and soft OFF to protect the lamp. Universal control voltage 8..230V UC, galvanically separated from the supply and switching voltage 230V. No minimum load required. Short control commands switch on/off, permanent control changes the brightness up to the maximum value. Interrupting the control changes the dimming direction. The set brightness level remains stored when switching off (memory). In the event of a power failure, the switching position and the brightness level are stored and, if necessary, switched on when the supply voltage returns. From 110V control voltage glow lamp current 5mA. Automatic electronic overload protection and overtemperature cut-off. There is an LED under the upper rotary switch on the front panel which indicates activation. It starts flashing after 15 seconds to draw attention to a possibly blocked control button. The upper rotary switch determines in operation whether the automatic lamp detection should work or special comfort settings: AUTO allows dimming of all lamp types. LC1 is a comfort position for dimmable 230V LED lamps that cannot be dimmed far enough on AUTO (phase control) due to their design and must therefore be forced to phase control. LC2 and LC3 are comfort positions for dimmable 230V LED lamps like LC1, but with different dimming curves. EC1 is a comfort position for energy-saving lamps which, due to their design, have to be switched on with a higher voltage so that they can be switched on again safely when dimmed down. EC2 is a comfort position for energy-saving lamps which, due to their design, cannot be switched on again when dimmed. Memory is therefore switched off in this position. LC1 is a comfort position for dimmable 230V LED lamps that cannot be dimmed far enough on AUTO (phase control) due to their design and must therefore be forced to phase control. LC2 and LC3 are comfort positions for dimmable 230V LED lamps like LC1, but with different dimming curves. No inductive (wound) transformers may be used in positions LC1, LC2, LC3, EC1 and EC2. In addition, the maximum number of dimmable LED lamps may be lower than in the AUTO position due to the design. The middle %lamp rotary switch can be used to set the minimum brightness (fully dimmed) or the maximum brightness (fully dimmed up). With the lower dim-speed rotary switch, the dimming speed can be set. At the same time, the duration of soft on and soft off is changed. With nursery circuit: When switching on with a longer push-button action, the light is switched on after approx. 1 second with the lowest brightness and, as long as the push-button action continues, is slowly dimmed up without changing the last stored brightness level. With snooze circuit: A double pulse dims the lighting from the current dimmer setting to the minimum brightness and switches it off. The max. dimming time of 60 minutes depends on the current dimming position and the set minimum brightness and can thus be shortened accordingly. You can switch off at any time during the dimming process by briefly pressing the button. A long keystroke during the dimming down process dims up and terminates the snooze circuit.
