UP 525S32 KNX Universal Dimming Actuator 1x AC 230V LED 1-200W 3 Binary Inputs Flush 5WG1525-2SB32
Product Overview
The KNX 1-fold universal dimming actuator is a flush-mounted device for flicker-free dimming of resistive, inductive, and capacitive loads. Rated for AC 230 V 50/60 Hz, it handles LED lamps from 1 to 200 W and conventional incandescent/halogen lamps from 20 to 230 W, covering both modern retrofits and legacy circuits in one unit.
Key Features
Automatic Load Detection: Selects leading edge or trailing edge dimming automatically with manual override for demanding load types
Built-in Protection: Electronic protection detects and reports open-circuit, short-circuit, and overtemperature via KNX bus
Flexible Inputs: Three potential-free binary inputs with 5 V internal poll voltage, independently configurable for switching, dimming, scene recall, value transmission, or paired operation
Advanced Dimming Functions: Status feedback, adjustable brightness limits, dimming curves, switch-on/off delays, staircase timer, and 1-bit/8-bit scene control
