Product Dimensions and Wiring
Product dimensions are 110mm (length) x 35mm (width) x 20mm (height). The minimum recommended hole size for installation is 40mm (1.57 inches).
Wiring Diagram (DALI Connection): Features screw terminals for AC input (L, N), DALI bus (DA, DA), and LED output (LED-W, LED-C, LED+). Recommended wire diameter for AC input and DALI is 0.75-1.5mm² (20-16AWG) with a strip length of 5-6mm. LED output wiring supports 0.5-1.5mm² (22-16AWG) with a strip length of 5-6mm. Dimming range is 0-100%, and color temperature range is 2700-6500K.
Four-wire LED connection is also illustrated.
The driver utilizes a constant power program design, maintaining consistent brightness during color temperature adjustments. It supports connecting twice the rated power load across two channels, ensuring the total power remains within the driver's limit (e.g., a 12W driver can support 2x12W loads, but the total output is capped at 12W).
Application Diagrams and Precautions
Protective Housing Application Steps:
- Use a tool to pry up the protective housing on the side panel.
- Pry up the protective housing in the side plate position with a tool.
- Connect electrical wires using a screwdriver as per the wiring diagram.
- Press down the tension plate to secure the electrical wires.
- Close the protective housing.
Installation Precautions:
- Ensure a minimum spacing of 15cm between products to maintain proper heat dissipation and lifespan.
- Avoid placing products directly on top of LED drivers; maintain a minimum distance of 15cm to prevent heat buildup and ensure longevity.
NFC Programmer and App Guide
Using the LT-NFC Programmer:
- Read Driver: Power the programmer via USB, select "NFC Driver Settings", and bring the programmer's sensing area close to the driver's NFC logo to read parameters.
- Change Parameters: Navigate the programmer interface to select and edit parameters like output current and DALI address. Save changes by pressing OK. Note: The programmer will report an error if the set current is out of range. DALI address range is 0-63.
- Write to Driver: Select ">> Ready to Write", confirm, and bring the programmer's sensing area close to the driver's NFC logo. "Write succeeded" indicates successful parameter transfer.
Using the NFC Lighting App:
- Scan the provided QR code to install the app (requires NFC-capable Android phone or iPhone 8/later with iOS 13+).
- Read/Write LED Driver: Open the app, select "Read/Write LED driver", and place your NFC-capable phone near the driver's NFC logo to read parameters.
- Switch Dimming Interface: In the "Edit parameters" section, select the desired interface: DT8 CT (1 channel), DT6 CT (2 channels), or DT6 DIM (various address/channel configurations).
- Edit Parameters: Access "Parameter settings" to adjust output current, DALI address, dimming curve, and advanced DALI templates. Save changes.
- Write to Driver: After settings are complete, click "Write" and place the phone near the driver's NFC logo to transfer parameters.
NFC Programmer Connection via App: Connect the NFC programmer to your phone via Bluetooth. Use the app to read driver parameters, edit solutions, sync to the programmer, and write advanced parameters to multiple drivers.
Advanced DALI Template: Integrate DALI lighting system functions by editing DALI groups and scene lighting effects. Save these as advanced templates for lighting programming. Access is available via the App's "DALI template on phone" or "DALI template on programmer" sections.
