Universal dimmer actuators GDA2K-400 KNX / GDA4K-400 KNX

Updated: Mai-17 (Subject to changes) Page 4 of 63

1 Functional characteristics

•

2-/4-way universal dimmer actuator

•

Dimming range 0–100%

•

For dimming incandescent lamps, low voltage and high voltage halogen lamps, dimmable
LED retrofit lamps

•

Also suitable for dimming dimmable energy-saving lamps via different dimming curves

•

Also suitable for controlling fans

•

LED switching status indicator for each channel

•

Manual operation on the device (even without bus voltage)

•

Dimming output: 400 W/VA per channel or 1 x 800 W/VA in parallel operation

•

Use of the 1-channel GBO-300 KNX dimming booster can increase dimming output by 300
W/VA.

•

Output of up to 2000 W/VA possible via max. 4 boosters in parallel operation (C1//C2)

•

Automatic load detection (can be deactivated)

•

For R, L and C-load

Dimming outputs > 1000 W for professional use only.
