Paulmanns URail dim/switch I white On/Off/Dimming: You want to switch or dim specific sections of your URail system? Dim/switch I can be controlled very comfortably using a separately available remote control and set to meet your individual needs. Using small slide control, select one of four channels which are controlled using the corresponding button on the remote control. Channel 1 and 2 switch downstream sections up to maximum 500 watt, channel 3 and 4 dim up to 1,000 watts. Please note that the dim function can only be used with ohmic loads, i.e. incandescent and halogen lamps. A fifth slide control provides you with the option of deciding whether the dim/switch should be permeable or already execute the required switch or dim operations upon switching on.
