PWM dimming switch with 4 channels for LED 12-36 V DC, each up to 2 A. Minimum brightness and dimming speed can be set. With snooze and light-wicker switch. Additionally with light-setting control via PC or with radio buttons. Encrypted radio, bi-directional radio and repeater function can be activated. Stand-by loss only 0.3-0.5 watt. Installation, for example, in suspended ceilings and lights. 252 mm long, 46mm wide and 31mm deep. With cable strain relief. 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. Encrypted sensors can be taught in. Bidirectional radio and/or a repeater function can be switched on. Each change in status and received central control message frames are then confirmed with a radio message frame. This radio telegram can be taught in to other actuators and the GFVS software. The current dimming value is also displayed in % in the GFVS software. The upper rotary switch is only required for programming. With the middle % rotary switch, you can set the minimum brightness (fully dimmed). The dimming speed can be set with the lower DIM speed rotary switch. The buttons can be programd either as direction buttons or as universal buttons: The direction buttons are then switched on and dimmed on one side and switched off and dimmed on the other side. Double-clicking on the power-on page triggers automatic dimming up to full brightness at dim speed. Double-clicking on the switch-off page triggers the snooze function. As a universal button, the direction is reversed by briefly releasing the button. Wireless motion brightness sensors FBH can be taught in as master or slave. Wireless brightness sensors FAH can be programd to switch off depending on the brightness or as a twilight switch. Light-setting control, light-witching and snooze according to the operating instructions. The LED accompanies the teach-in process according to the operating instructions and indicates control commands during operation by a short flash.This text is machine translated.
