Application Scenarios
Installation and Wiring Guide
- Ensure AC power is disconnected before starting the installation.
- Mount the DALI-PS-DIN unit securely onto a standard DIN rail inside a suitable electrical enclosure.
- Connect the mains AC power (100-240V) to the 'L' (Live) and 'N' (Neutral) input terminals.
- Connect the two wires of your DALI bus cable to the 'DALI+' and 'DALI-' output terminals. DALI is polarity-insensitive, so the wires can be connected to either terminal.
- Run the DALI bus cable to your DALI devices, such as a DALI master controller, DALI dimming drivers, and sensors.
- After verifying all connections are secure, restore AC power to the unit.
- This product is designed for indoor use only. Do not expose to moisture.
- Ensure sufficient space around the unit for natural air cooling. Do not operate in a sealed, unventilated enclosure.
- This is a DALI bus power supply, not an LED driver. Do not connect LED lights or strips directly to the DALI output terminals.
- For a complete wiring diagram, please refer to the DALI-PS-DIN datasheet available in the Downloads section below.

Frequently Asked Questions
Q: What is the purpose of a DALI bus power supply?
A:It provides the essential low-voltage power (15Vdc) for the DALI communication bus, allowing devices like controllers, sensors, and DALI dimmers to communicate. It does not power the LED lights directly.
Q: How many DALI devices can this power supply support?
A:The DALI-PS-DIN provides 200mA, which is the standard capacity to power a full DALI line of up to 64 addressable devices, as each device typically draws about 2mA from the bus.
Q: Is this a DALI dimmer or controller?
A:No, this is a power supply unit (PSU) designed specifically to power the DALI control bus. You need separate DALI master controllers and DALI dimming drivers to control and dim your lights.
Q: Can I use a generic 15V power supply instead of this?
A:It is strongly recommended to use a dedicated DALI bus power supply. The DALI-PS-DIN is specifically designed to meet the unique current, voltage, and safety requirements of a DALI lighting system.
Q: Does this unit require programming or a DALI address?
A:No, this power supply is a foundational component that does not have a DALI address and requires no programming. It works immediately upon being correctly wired and powered on.
Q: What is the main benefit of the DIN rail mounting?
A:DIN rail mounting allows for clean, organized, and secure installation inside standard electrical enclosures and control panels, which is the professional standard for commercial and industrial installations.
