Universal dimmer switch for power MOSFETs up to 300W. Automatic lamp detection. Standby loss of only 0.7 watts. Minimum brightness or dimming speed adjustable. Features children's room, snooze, and light alarm functions. Additionally equipped with light scene control. Encrypted wireless, bidirectional wireless, and repeater function can be activated. Designed for flush mounting. Dimensions: 45 mm long, 45 mm wide, 33 mm deep. Universal dimmer switch for lamps up to 300W, depending on ventilation conditions. Dimmable energy-saving lamps (ESL) and dimmable 230V LED lamps are also dependent on the lamp electronics. Circuit operates at zero crossing with soft on and soft off for lamp protection. Supply, switching, and control voltage locally 230V. No minimum load required. The set brightness level is saved when switched off (memory). In the event of a power failure, the switching position and brightness level are saved and can be turned on again when the supply voltage returns. Automatic electronic overload protection and over-temperature shut-off. Encrypted sensors can be learned. Bidirectional wireless and/or a repeater function can be activated. Every state change and received central control telegrams are confirmed with a wireless telegram. This wireless telegram can be learned into other actuators such as FSR61NP-230V, the GFVS software, and universal displays. The GFVS software also displays the current dimming value in %. The upper % lamp/dim speed rotary switch can set either the minimum brightness (fully dimmed) or the dimming speed. The lower rotary switch determines whether the automatic lamp detection should be active or specific comfort settings. The LED indicates the learning process according to the user manual and signals wireless control commands during operation with a brief flash.
