DA-P DALI Push Dimmer | 100–240V Inline Push Controller

Overview

The DA-P DALI Push Dimmer is a compact single-channel controller designed to operate DALI drivers or ballasts using a conventional push-button switch. Powered directly from 100–240V AC, it converts simple push commands into DALI dimming signals, providing smooth brightness control, on/off switching, memory function and adjustable dimming speed. Its small inline housing makes it ideal for installation behind a wall switch or inside a junction box for residential and commercial lighting applications.

Key Features

• Compact DALI push dimmer for DALI drivers and ballasts
• Input voltage: 100–240V AC
• Control via standard momentary push-button switch
• Short press for on/off, long press for dimming up/down
• Adjustable dimming speed via rotary knob
• Memory function for last brightness level on power up
• Unidirectional, broadcast DALI communication to connected devices
• Designed for retrofit and new installations
• Ultra-compact housing for mounting behind switches or in small boxes

Technical Notes

• DA-P is intended for use with DALI-compliant LED drivers or ballasts only.
• Communication is unidirectional and broadcast, controlling all connected DALI devices on the line.
• Input and output share the same 100–240V AC supply; maximum output current is 0.05A.
• Dimming behaviour and minimum brightness depend on the connected DALI drivers.
• Memory function can be configured to restore last level or a defined level after power loss.
• Dimming speed is adjustable using the built-in rotary control on the device.
• Ensure all DALI drivers on the line are compatible with broadcast dimming control.

Wiring & Installation Notes

• Connect the DA-P to the 100–240V AC supply (L and N) according to the wiring diagram.
• Connect the output terminals to the DALI input of the driver or ballast as specified in the datasheet.
• Connect a momentary (non-latching) push-button between live and the push-input terminal.
• Short press on the push-button switches the connected lighting on or off.
• Long press dims the lighting up or down; repeated long presses alternate the dimming direction.
• Install the unit in a dry, ventilated location such as behind a wall switch or inside a junction box.
• Observe all local electrical regulations and ensure wiring is carried out by qualified personnel.
• Operating temperature range: approximately -30°C to +55°C; avoid enclosed spaces with excessive heat.

Applications

• Residential dimming of DALI LED drivers and ballasts
• Retrofit projects using existing wall push-buttons
• Commercial and office lighting with DALI drivers
• Corridor, lobby and circulation area lighting control
• Small DALI lighting groups requiring simple local push control
