Description
KL2751 | Bus Terminal, 1-channel universal dimmer, 230 V AC, 300 VA
The KL2751 dimmer Bus Terminal is intended for direct connection of different lighting devices. Dimmable lighting devices such as incandescent lamps, inductive and electronic ballasts, are detected and controlled in the correct operating mode. The required brightness values are specified via the process data. The KL2751 calculates the correct phase control angle in leading or trailing edge phase control for the required value. The output is short-circuit-proof and overload-proof. The KL2751 can be operated at any fieldbus. The load status can be read.
The KL2751 is also available as KL2751-0011 variant without power contacts.
