LTSYS SE-12-100-450-W1D DALI-2 DT6 Intelligent LED Driver
Constant Current LED Driver with DALI-2 DT6 Control
Product Overview
The LTSYS SE-12-100-450-W1D is an intelligent LED driver designed for constant current applications. It features a small size and lightweight construction with a clamshell design and screwless strain relief. The dismountable end cap allows for adjustable housing length. It supports multiple current levels and a wide voltage range, making it suitable for various LED power requirements. The driver complies with EU's ErP Directive for no-load power consumption (< 0.5W) and features standby power consumption below 0.5W. It offers soft-on and fade-in dimming for enhanced visual comfort and utilizes T-PWM dimming technology for continuous, flicker-free images, even under high-speed photography. The dimming process is flicker-free with high-frequency exemption levels, allowing dimming from 0-100% down to 0.1%. It adheres to DALI bus standards (IEC62386-101, 102, 207) and supports linear and logarithmic dimming curves. The design includes secure signal isolation, innovative thermal management for longevity, and comprehensive protection against overheat, over-voltage, overload, and short circuits with automatic recovery. It is suitable for Class I/II/III indoor light fixtures and offers a lifetime of up to 50,000 hours, backed by a 5-year warranty (using Rubycon capacitors).

LED Current Selection
The driver features DIP switches for quick selection of 8 current levels:
| DIP Switch Setting | Output Current | Output Voltage | Output Power |
|---|---|---|---|
| 1 2 3 (OFF OFF OFF) | 100mA | 9-42V | 0.9-4.2W |
| 1 2 3 (OFF OFF ON) | 150mA | 9-42V | 1.35-6.3W |
| 1 2 3 (OFF ON OFF) | 200mA | 9-42V | 1.8-8.4W |
| 1 2 3 (OFF ON ON) | 250mA | 9-42V | 2.25-10.5W |
| 1 2 3 (ON OFF OFF) | 300mA | 9-40V | 2.7-12W |
| 1 2 3 (ON OFF ON) | 350mA | 9-34V | 3.15-11.9W |
| 1 2 3 (ON ON OFF) | 400mA | 9-30V | 3.6-12W |
| 1 2 3 (ON ON ON) | 450mA | 9-27V | 4.05-12.15W |
Note: After setting the current via DIP switches, power cycle the driver for the new setting to take effect. Example: For LEDs with 3V/piece, a 9-42V range can power 3-14 LEDs in series. The maximum number of LEDs in series depends on their actual voltage.

Protective Housing Application Diagram
The diagram illustrates a 5-step process for installing the protective housing:
- 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 to electrical wires with a screwdriver as shown in the wiring diagram.
- Press down the tension plate to fix the electrical wires.
- Close the protective housing.
Performance Graphs
The document includes performance graphs illustrating the driver's characteristics:
- Power Factor vs. Load: This graph shows the power factor on the Y-axis (ranging from 0.4 to 1.0) against the load percentage on the X-axis (0% to 100%). Multiple lines represent different current settings (100mA to 450mA). The power factor remains high across the tested load range for all current settings.
- Efficiency vs. Load: This graph displays efficiency percentages (from 25% to 90%) on the Y-axis against the load percentage on the X-axis (0% to 100%). Multiple lines represent different current settings. The efficiency is shown to be optimal at higher load percentages, typically above 50%.
- THD vs. Load: This graph illustrates Total Harmonic Distortion (THD) percentages (from 7% to 87%) on the Y-axis against the load percentage on the X-axis (0% to 100%). Multiple lines represent different current settings. The THD is generally low, especially at higher loads, and tends to increase slightly at lower load percentages.
Flicker Test and IEEE 1789 Compliance
The product is designed to meet the IEEE 1789 standard for flicker reduction. A Flicker Test Form table defines the limits of modulation for low-risk and no-effect areas based on waveform frequency. A "Modulation Area Diagram" plots tested results against frequency (X-axis, logarithmic) and modulation percentage (Y-axis, logarithmic). This diagram categorizes areas as "IEEE 1789 High Risk", "IEEE 1789 Low Risk", and "IEEE 1789 No Effect". The tested results shown in the diagram fall within the "No Effect" or "Low Risk" zones, indicating good flicker performance.
