DALI & Push AC Phase Cut Dimmer SR-2303SAC-HP

The SR-2303SAC-HP is a compact DALI-2 AC phase-cut dimmer designed for reliable control of dimmable LED lighting, incandescent lamps, and halogen loads.

It features a 100–240VAC universal input and output, one dimming channel, and supports loads up to 400W. The dimmer uses trailing-edge phase-cut dimming for smooth and stable light control.

The built-in DALI-2 interface allows integration with standard DALI lighting control systems, while the additional Push-Dim input allows the dimmer to be controlled directly from a conventional momentary push button, even without a DALI controller.

A useful minimum brightness setting allows the installer to define the lowest dimming level for the connected load. This can help prevent LED flicker or unstable operation at very low brightness levels.

Key Features

• DALI-2 compatible
• DALI DT6 device
• Compliant with IEC 62386-101:2014, IEC 62386-102:2014 and IEC 62386-207 Ed.2
• 1 DALI address
• 1-channel output
• Maximum output power: 400W
• 100–240VAC input and output
• Trailing-edge phase-cut dimming
• Suitable for compatible dimmable LED, incandescent, and halogen lighting
• Supports resistive and capacitive loads
• Adjustable minimum brightness level
• Built-in Push-Dim control input
• Compatible with universal 8V–230V push-button inputs
• Screw-terminal connections
• Compact design for installation in suitable electrical/wall boxes

Control Options

The SR-2303SAC-HP can be controlled through:

DALI / DALI-2
Connect to a DALI controller or DALI gateway for addressable lighting control.

Push-Dim
Connect a standard momentary push button for direct switching and dimming without requiring a DALI control system.

Typical Applications

Ideal for residential and commercial lighting installations where conventional phase-dimmable fixtures need to be integrated into a DALI or KNX-DALI lighting system.

It is particularly useful for converting standard trailing-edge dimmable LED fixtures into individually addressable DALI lighting loads.
