PWM dimmer switch with 4 channels for LED 12-36V DC, each up to 2A. Minimum brightness and dimming speed adjustable. With snooze and light alarm function. Additionally with light scene control via PC or with radio buttons. Encrypted radio, bidirectional radio and repeater function can be switched on. Standby loss only 0.3 - 0.5 watts. Installation in false ceilings and lights, for example. 252mm long, 46mm wide and 31mm high. With cable strain relief. The set brightness level is saved when switched off (memory). In the event of a power failure, the switch position and brightness level are saved and switched on when the supply voltage returns. Automatic electronic overload protection and overtemperature shutdown. 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 and Professional Smart Home controllers. The current dimming value in % is also displayed in the Professional Smart Home controller. The upper rotary switch is only required for teaching. The middle % lamp rotary switch can be used to set the minimum brightness (fully dimmed). The lower dim-speed rotary switch can be used to set the dimming speed. The buttons can be taught in either as directional buttons or as universal buttons: As a directional button, one side can be used to switch on and dim up, and the other side can be used to 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. As a universal button, the direction is reversed by briefly releasing the button. Radio motion brightness sensors FBH can be programmed as master or slave. Radio brightness sensors FAH can be programmed to switch off depending on the brightness or as a twilight switch. Light scene control, light alarm and snooze function as per operating instructions. The LED accompanies the learning process in accordance with the operating instructions and indicates control commands during operation by flashing briefly.
