Product Description


  • Installs at the breaker panel/fuse box for X10 control of branch lighting circuits rated up to 700W.
  • Controlled via X10 controllers or momentary action wall switches, including "designer" wall switches.
  • Designed to operate with 230V lighting including mains halogen.
  • Remembers its light level for smooth dimming.

The Marmitek DIN rail dimmer is a 700W receiver unit that works as a remote dimmer. Mounted on the "Top Hat" DIN rail in the mains distribution box, it dims or switches hardwired circuits with several wall switches (eg. Living room lighting). It is designed to operate with 230V lighting including mains halogen.

The unit can be turned on/off, and brightened/dimmed either by an X10 controller or by external momentary action switches connected to Terminal 2. It responds to "standard" X10 commands. ie. All-Lights-On, All-Units-Off, On, Off, Bright and Dim. It also responds to extended X10 commands. Combined with the memory dim feature, the LD11 can change the room lighting instantly or progressively. This unit is especially designed for scene lighting where very often the lighting is mains powered 12V halogen, commonly used in living room, study/reading rooms. The unit can be installed in sub-junction boxes for discrete control.


This Marmitek unit can control branch lighting under X10 control or, if momentary switches are installed, with designer style wall switches.

When mounting more LD11 dimmers next to each other, depending on the load per LD11, keep an extra distance of 2 cm between each LD11 to ensure the heat dissipation. With the help of additional momentary switches on input 2, the module can be switched on or off by a short key press and can be dimmed by a long key press.
