KL2751 | 1-channel universal dimmer terminal 230 V AC, 300 VA (W)


The KL2751 dimmer Bus Terminal is designed for direct connection of different lighting devices. Dimmable lighting devices such as incandescent lamps, inductive and electronic ballasts are detected and controlled in the right mode. The required light intensity values are specified via the process data. The KL2751 calculates the correct phase control angle 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.
