Cebek R-41 module is a   night to day and day to night dimmer for LED tape. There are four  different time  settings you can select: 1 - 60 sec / 1 - 30 min / 30 - 60 min or 1 - 2  hours. The time  scale you require is achieved by a PCB mounted potentiometer and DIL  switches. It has a rest function and the effect is activated by a change   over switch. When used in conjunction with
E305DIN1, it allows an automatic  switching between the day and the night, functions. When you turn the  power on or change the switch position from Day/Night or Night/Day the circuit  initiates the sequence effect. In day mode, the output starts off to  progressively increase until the maximum brightness level. In night mode, the  output begins to decrease progressively until the LED tape is off. In both  modes, after the ramp increases or decreases, the output will remain fixed in  that state. The reset switch allows ypu to restart the cycle again. This  module will not control inductive loads or LED lamps. The Cebek R-41 dimmer module is  suitable for use in a child's bedrooms or aviaries.
