Dimmer terminal with automatic load detection and short-circuit-proof output

Universal dimmer in the Bus Terminal

The KL2751 dimmer Bus Terminal is designed for direct connection of different AC consumers. Typical lighting devices such as incandescent lamps, inductive and electronic ballasts are detected and controlled in the right mode. In addition to automatic load detection, the Bus Terminal offers a short-circuit-proof and overload-proof output.

The KL2751 is a universal 230 V dimmer in very compact Bus Terminal format, designed for building services applications. The brightness values of the lighting system can be modified via the controller process data, based on any bus system supported by the Beckhoff I/O system. The universal dimmer can also be used as an AC power switch. A switchable load of 350 W enables wear-free switching of a wide range of consumers.

The dimmer terminal automatically detects the load type and calculates the correct phase control angle as required. Load detection occurs once after start-up. The result is stored in the Bus Terminal. The dimmer terminal is short-circuit-proof. It limits the current in the event of a short circuit, thereby protecting the load and preventing triggering of the main fuse.
