Depending on configuration and LED type, this Dimmer can control LEDs with a total of 300W (4x 75W) power. Recommended areas of use are all areas in which healthy lighting is ensured, as the effects of conventional PWM dimming have not been fully investigated, but are classified by experts as posing a health risk. PWM is used as standard in all previous LED Dimmers, including the DALI and KNX/EIB standards. Therefore, the use of non-PWM dimming is particularly recommended in areas where people stay longer or where high demands are placed on lighting quality:
The LED Dimmer can be operated either on the ISYGLT-BUS or DMX512-BUS.
The following functions can be performed independently by the LED Dimmer:
| Operating voltage | 24V to 56V for the supply of the LEDs depending on the type |
| Emergency operation input | 24V to 56V DC |
| LED forward voltage | 12V to 54V (depending on the voltage drop of the line); the LED forward voltage including the voltage drop of the line must be 2V lower than the supply voltage! |
| Mains fuse | max. 16A at Umax 56V DC |
| Current consumption | max. 1550mA per LED circuit |
| Output | 4 x constant current, separately adjustable in the factory with 250mA to 1550mA each for power LEDs (please specify the desired current value for each circuit when ordering) |

| BUS control | ISYGLT / DMX512 8/16-bit (others on request) |
| Cable length power supply to LED dimmer | max. 20m (observe max. permissible voltage drop for cable cross-section calculation) |
| Cable length LED dimmer up to last LED | max. 50m |
| Dimming resolution | 16 Bit |
| Subnet (RS-485) | max. 5.6V limitation by Z-diodes |
| Connection | screw terminals 2.5mm² |
