The LED Dimmer was developed for the control of 3 LED lights 700mA. Thus it is possible to control the light emitting diodes in the brightness between 0 and 100% absolutely flicker-free with a dimming resolution of 16 bits (internal resolution with ISYGLT operation).
The LED Dimmer can be set from speed calculation to absolute time calculation by parameterisation per channel. All imaginable control tasks, from individual light dimming to the use for complex light and colour scenarios, can be easily realised.
The LED Dimmer can optionally be operated on the ISYGLT-BUS or DMX512-BUS.
The regular DMX GND connector on PIN 1 is not required and therefore not connected.
The following functions can be performed autonomous by the LED Dimmer:
| Operating voltage | 12V to 55V DC impulse-proof for Power-LEDs |
| Emergency input | 12V to 55V DC |
| Fuse protection | max. 16A at Umax 55V DC |
| Current consumption | max. 750mA per LED circuit, BUS interface 10mA |
| Output |
3 circuits with 700mA each for LEDs The required voltage for series connection of LEDs can be found in the respective data sheets of the LED manufacturers. The supply voltage must be 25% higher than the forward voltage of the LED. |
| BUS control | ISYGLT / DMX512 (others on request) |

DIP switches 3 to 10 are used to set the DMX address. The set address, multiplied by 3 and added by 1, corresponds to the first of 3 consecutive DMX addresses:
- Address 0, 00000000 = DMX 1, 2 and 3
- Address 1, 00000001 = DMX 4, 5 and 6
- Address 169, 10101001 = DMX 508, 509 and 510
For higher switch positions, the address is always limited to channel 508...510.
