SCHNEIDER ELECTRIC REG-K/4x230/250W Used Working KNX Home Automation Universal Dimmer

Product Overview

The Schneider Electric REG-K/4x230/250W (Part Number: MTN649325) is a premium 4-channel KNX Universal Dimming Actuator designed for high-end home and building automation. This versatile module automatically detects the connected load type—whether it be incandescent lamps, halogen lamps, or dimmable LEDs—and selects the appropriate dimming method (Leading or Trailing Edge). Each of the four channels can manage up to 250W, providing smooth, flicker-free dimming transitions and sophisticated scene management. This Used Working unit offers a cost-effective way to expand or maintain a KNX-certified intelligent lighting system with genuine Schneider engineering.

Key Features

• Universal Load Detection: Automatically adjusts between phase-cut (leading edge) and phase-section (trailing edge) dimming based on the load (R, L, or C).
• 4-Channel Independent Control: Manage four separate lighting zones from a single 8-module wide DIN rail unit.
• KNX Certified: Seamlessly integrates into any KNX ecosystem, allowing for complex logic, timers, and multi-room scene control via ETS software.
• Manual Override: Each channel features a local toggle switch on the front panel for manual operation, allowing for testing and commissioning without the bus being active.
• Advanced Diagnostics: Provides feedback to the KNX bus regarding short circuits, overloads, or wire breaks for rapid maintenance alerts.
• Soft Start & Stop: Protects sensitive lamp filaments and LED drivers by gradually ramping power up and down, extending the lifespan of your lighting fixtures.
• Energy Efficient: Optimized for low standby power consumption, contributing to the overall green building certification of your project.

Item Condition (Used - Working)

• Functional Status: Used - Working. This unit has been professionally decommissioned from a high-end residential KNX installation. It has been tested for bus communication and dimming performance across all four channels.
• Physical State: Shows minor signs of installation, such as light surface scuffs. The DIN rail clip is secure, and all terminal screws are present and move freely.
• Visual Reference: Please examine the high-resolution photos to verify the specific hardware version; the unit pictured is the exact Schneider KNX Dimmer you will receive.
