LED Current Selection
The output current can be set using DIP switches. Ensure the driver is powered off before setting the current. Power on the driver again for the setting to take effect. Failure to power off may damage the light fixture.
Example: For LEDs with 3V per piece, a 9-42V output voltage range can power 3-14 LEDs in series. The maximum number of LEDs in series depends on the actual LED voltage.
| DIP Switch Setting | Output Current | Output Voltage | Output Power |
|---|---|---|---|
| 1 2 3 | 100mA | 9-42V | 0.9-4.2W |
| 1 2 3 | 150mA | 9-42V | 1.35-6.3W |
| 1 2 3 | 200mA | 9-42V | 1.8-8.4W |

Wiring Diagram
DALI Connection Mode:
AC Input: Connect Live (L) and Neutral (N) wires to the primary side terminals.
DALI Bus: Connect DALI control wires to the 'DA' terminals on the secondary side.
LED Output: Connect the LED module's positive (+) terminal to 'LED+', negative (-) terminal to 'LED-', and common (-) terminal to 'LED-C'.
Recommended wire diameter for AC input and DALI: 0.75-1.5 mm² (22-16 AWG).
Recommended wire diameter for LED output: 0.5-1.5 mm² (22-16 AWG).
Strip length for all connections: 4.5mm-5mm.
The driver supports CCT (Correlated Color Temperature) adjustment from 2500K to 6000K, maintaining consistent brightness.
The driver can connect loads up to twice its rated power, and for 12W drivers, it can support 12W x 2 channels, with the total power of both channels not exceeding 12W.

Performance Characteristics
The following charts illustrate the performance of the LED driver under various load conditions and current settings:
Power Factor Characteristic Curve
This chart shows the Power Factor (PF) on the y-axis against Load (%) on the x-axis for different output currents (100mA to 450mA). Generally, PF increases with load and approaches 1.0 at higher loads.
Efficiency VS Load
This chart displays Efficiency (%) on the y-axis against Load (%) on the x-axis for different output currents. Efficiency typically rises with load, peaking at higher loads.
THD Characteristic Curve
This chart plots Total Harmonic Distortion (THD) in percentage (%) on the y-axis against Load (%) on the x-axis for different output currents. THD generally increases with load, especially at lower loads.
Graphs depicting Power Factor, Efficiency, and THD performance across different load percentages and current settings.
Flicker Test
The Flicker Test Table and IEEE 1789 chart provide information on flicker levels according to the IEEE 1789 standard, which relates waveform frequency to modulation depth for risk assessment.
Flicker Test Table: Lists limit values for modulation depth (%) based on waveform frequency (Hz) in Low Risk and No Effect areas.
IEEE 1789 Chart: A graphical representation categorizing flicker risk (High Risk, Low Risk, No Effect) based on frequency and modulation. Marks on the chart indicate tested results for different current levels.
Note: At 100% brightness, the output frequency is 0Hz, and the modulation is 0%, which is not explicitly shown on the chart.
