DALI & Push AC Phase Cut Dimmer, Pre-Wired SR-2303SAC-HPW

The SR-2303SAC-HPW is a compact DALI-2 AC phase cut dimmer with pre-wired leads instead of screw terminals. It controls dimmable LED lamps, incandescent and halogen lighting.

It works with 100-240VAC input and output, has one dimming channel and handles loads up to 400W. The dimmer uses trailing edge dimming for smooth and quiet light control.

The built-in DALI-2 interface connects it to any standard DALI lighting control system. The extra Push-Dim input lets you switch and dim the light from a normal push button, even without a DALI system.

A minimum brightness setting lets the installer set the lowest dimming level of the connected light. This helps to avoid LED flicker at very low 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
• Pre-wired leads, no visible terminals
• Trailing edge phase cut dimming for resistive and capacitive loads
• Adjustable minimum brightness level
• Single wire Push-Dim input, works with standard push buttons from 8V to 230V
• Small size, fits into a standard wall box

Control Options

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

• DALI / DALI-2: connect it to a DALI controller or DALI gateway for addressable lighting control.
• Push-Dim: connect a standard momentary push button to switch and dim without a DALI system.

Typical Applications

Homes and commercial buildings where standard phase dimmable lights should become part of a DALI or KNX-DALI lighting system.

Choose this pre-wired version when you prefer flying leads. The SR-2303SAC-HP is the same dimmer with screw terminals.
