UP 525S32 KNX Universal Dimmer 1-Fold LED 1-200W Lamps 20-230W Flush Mount 5WG1525-2SB32
The KNX universal dimmer is a compact 1-fold flush-mounted device for switching and dimming resistive, inductive, and capacitive loads. It installs in appliance boxes per DIN 49073 or in the M 592/01 mounting case. The dimmer automatically or manually adjusts to leading edge or trailing edge control depending on load type, with built-in protection against open-circuit, short circuit, and overtemperature.
The unit provides one output rated for AC 230 V, supporting 1 to 200 W LEDs and 20 to 230 W conventional lamps. Three binary inputs for potential-free contacts allow direct operation and status detection via internally generated voltage, with poll voltage approx. 5 V and max. cable length 10 m. The device is bus-powered and includes an integrated bus coupling unit.
