Without N connection, power MOSFET up to 300W. Standby loss only 0.7 watts. Minimum brightness and dimming speed adjustable. With children's room and snooze function. Light scenes can be programmed. Encrypted radio, bidirectional radio and repeater function can be switched on. For recessed installation. 45mm long, 45mm wide, 33mm deep. Universal dimmer switch for R, L and C loads up to 300W, depending on the ventilation conditions. Automatic detection of load type R+L or R+C. Without N connection, therefore suitable for installation directly behind the light switch, even if there is no N cable. Not suitable for 230V LED lamps and energy-saving lamps ESL, please use the FUD61NPN dimmer with N connection. Local supply, switching and control voltage 230V. Minimum load only 40W. Zero-crossing switching with soft on and soft off to protect the lamp. The set brightness level is saved when the lamp is switched off (memory). In the event of a power failure, the switch position is saved and switched on when the supply voltage returns. Automatic electronic overload protection and overtemperature shutdown. The minimum brightness (fully dimmed) can be set using the %lamp rotary switch. Up to 35 radio buttons can be assigned in the LRN position, including one or more central control buttons. The dimming speed can be set using the dim-speed rotary switch. The duration of soft on and soft off is changed at the same time. In addition to the radio control input via an internal antenna, this universal dimmer switch can also be controlled locally using a conventional 230V control button that may be mounted in front of it. Encrypted sensors can be taught in. Bidirectional radio and/or a repeater function can be switched on. Every change in status and incoming central control telegrams are then confirmed with a radio telegram. This radio telegram can be taught into other actuators such as the FSR61NP-230V, Professional Smart Home Controller and universal displays. The current dimming value in % is also displayed in the respective app. The radio buttons can be taught in either as direction buttons or as universal buttons: As a direction button, one side has switch on and dim up, and the other side has switch off and dim down. A double click on the switch on side triggers automatic dimming up to full brightness at dim speed. A double click on the switch off side triggers the snooze function. The children's room switch is carried out on the switch on side. As a universal button, the direction is reversed by briefly releasing the button. Short control commands switch on/off. Light scene control, children's room switch and snooze function as per the operating instructions.The LED accompanies the learning process according to the operating instructions and indicates radio control commands during operation by flashing briefly.
