Radio universal dimmer actuator. With power MOSFET. Dimmable 230V LED lamps in trailing edge mode up to 300W, or in leading edge mode up to 100W, depending on the ventilation conditions. 230V incandescent and halogen lamps up to 300W, depending on the ventilation conditions. No inductive (wound) transformers. With children's room and snooze function. No minimum load. Standby loss only 0.5 watts. For built-in installation. 49x51mm, 20mm deep. The connection terminals are plug-in terminals for conductor cross-sections from 0.2mm² to 2.5mm². Up to 32 radio universal buttons, radio direction buttons, radio central control buttons and motion sensors can be taught in using the convenient tap technology. Bidirectional radio can be activated. Switching in zero crossing with soft on and soft off to protect the lamp. Local supply, switching and control voltage 230V. The set brightness level is saved when switched off (memory). If the supply voltage fails, the device switches off in a defined manner. Automatic electronic overload protection and overtemperature shutdown. In addition to the radio control input via an internal antenna, this radio actuator can also be controlled locally with a conventional 230V control button that may be mounted in front of it. A glow lamp current is not permitted.
