Technical Specifications

Product Size & Wiring

Product Dimensions: 127mm (Length) x 40mm (Width) x 23mm (Height).

Mounting Hole Size: Minimum 48mm (1.89 inches) diameter.

Wiring Diagram for 0-10V Connection:

• 1. Brightness Adjustment: Connect AC input (L, N) to PRI terminals. Connect LED load (LED-W, LED-C, LED+) to output terminals. Use DIM- and DIM+ terminals for 0-10V brightness control. Wire diameter: 0.75-1.5mm² (20-16AWG). Strip length: 5-6mm.
• 2. Color Temperature Adjustment: Similar connection as brightness adjustment, but use CCT+ and DIM+ terminals for 0-10V color temperature control. Wire diameter: 0.5-1.5mm² (22-16AWG). Strip length: 5-6mm.
• 3. Separate Brightness and Color Temperature Adjustment: Shows wiring for independent control of brightness and color temperature.
• 4. Simultaneous Brightness and Color Temperature Adjustment: Shows wiring for combined control using a four-wire LED connection (LED-W, LED-C, LED+, and a common connection).

Constant Power Program Design: This feature allows connecting up to twice the rated power load. For example, a 20W driver can support two 20W channels, with the total power across both channels maintained within the 20W limit.

Typical Current Parameters

The table below provides typical output voltage and power for various output current settings, which can be further customized via the NFC mobile APP (100-700mA range, 1mA step):

Installation and Usage

Application Diagram of Protective Cover

1. Removing the Cover: Use a flat-head screwdriver to pry open the protective cover and wire fixing board from the side of the housing. Disconnect the wire fixing board and connect the wires according to the wiring diagram.

2. Reattaching the Cover: Install the wire fixing board and press it down. Then, snap the protective cover back into place while holding the wire fixing board with a small flat-head screwdriver.

Installation Precautions

• Heat Dissipation: Do not stack products. Maintain a minimum distance of 15cm between products to ensure proper heat dissipation and longevity.
• Placement: Do not place products directly on top of LED drivers. Maintain a minimum distance of 15cm from drivers to avoid affecting heat dissipation and product lifespan.
• Environment: Ensure the installation area's temperature is within the product's working temperature range. Avoid installing inside LED fixtures where temperatures may exceed limits, potentially affecting product life.

Using the NFC Lighting APP

App Installation: Scan the provided QR code with your NFC-capable smartphone (Android with NFC, or iPhone 8 and later with iOS 13 or higher) and follow the prompts.

Important Note: Ensure the driver is powered off before setting any parameters.

Read/Write LED Driver Functionality:

1. Read Driver: On the APP home screen, tap "Read/Write LED driver". Place your phone's NFC sensing area close to the driver's NFC logo to read its parameters.
2. Edit Parameters: Navigate to "Parameter settings" to modify advanced settings like output current, dimming mode, and power-on fading time.
3. Write to Driver: After editing parameters, tap "Write" in the upper right corner. Place your phone's NFC sensing area close to the driver's NFC logo to successfully write the new settings.

Performance Diagrams

The following graphs illustrate the driver's performance characteristics:

• Efficiency VS Load: Shows the relationship between efficiency and load percentage for various current settings.
• Power Factor VS Load: Displays power factor values across different load percentages for various current settings.
• THD VS Load: Illustrates Total Harmonic Distortion (THD) levels relative to the load percentage for different current settings.
• Lifetime VS Housing Temperature: Indicates the estimated product lifetime in hours based on the housing temperature.

Flicker Test Sheet

This section details flicker test results and compliance with IEEE 1789 standards for flicker and modulation. It includes:

• Modulation Limits: Defines modulation depth limits for low-risk, high-risk, and no-effect zones based on waveform frequency.
• Test Results: Marks on the diagram indicate tested results for different current ranges.
• Note: At 100% brightness, the output frequency is 0Hz with 0% modulation, which is not visually represented on the chart.
