LTECH SN Series NFC Programmable Soft-Start LED Drivers 15–240W Flicker-Free

LTECH LED drivers offer a complete range of power ratings and form factors, meeting selection requirements for various fixture types and installation methods.

1. Two Main Series Covering Multiple Power Ranges

The lineup is divided into two primary categories: soft-start drivers and standard drivers, with power ratings ranging from 15W to 240W. The soft-start series focuses on delivering a premium lighting experience, while the standard series emphasizes cost-effectiveness for engineering applications. They are further categorized by output type into constant current versions (suitable for spotlights, track lights, etc.) and constant voltage versions (suitable for LED strips, light boxes, etc.).

2. Ultra-Compact Design

The entire series features a narrow, ultra-slim design. Taking the SN-30-24-G1NF model as an example, the housing cross-section measures just 30mm x 17mm-with a height lower than a standard coin-allowing for easy integration into tight spaces like magnetic tracks and light channels. This meets aesthetic requirements for concealed installation and significantly simplifies wiring.

3. Specialized Form Factors for Custom Needs

In addition to standard external plastic-cased drivers, the series includes specialized internal board-level drivers for magnetic track lights. These are directly compatible with STUCCHI standard housings (9519-166-K, B 9519-166-K/W), enabling driver upgrades without modifying the fixture structure and ensuring compatibility with mainstream magnetic lighting systems.

With a focus on practical engineering utility, LTECH LED drivers leverage full-rated power designs and strong load compatibility to effectively reduce project costs and O&M risks.

1. Full-Rated Power Output

The entire product series features a full-rated power design, supporting stable, long-term operation at maximum load without the need for additional power headroom. During the selection process, models can be matched directly to actual load requirements, avoiding unnecessary specification upgrades; this ensures reliability while enhancing cost-effectiveness and lowering overall project costs.

2. Wide-Range Load Compatibility

These power supplies boast excellent dynamic load regulation capabilities, maintaining stable output even when paired with constant-voltage or constant-current LED controllers for dimming or in scenarios involving fluctuating load power. Whether driving low-wattage spotlights or long-run LED strips, they ensure stable operation and are compatible with mainstream dimming control systems on the market.
 

To meet the visual comfort demands of high-end lighting, this series has been optimized for flicker control and synchronous startup consistency, achieving professional healthy lighting standards.

1. Flicker-Free Performance (High-Frequency Exemption)

The products meet the IEEE 1789 high-frequency exemption criteria and comply with CIE SVM standards (Pst LM ≤ 1.0, SVM ≤ 0.4), completely eliminating visual fatigue caused by low-frequency flicker. They produce no visible banding or "water ripple" effects when photographed with mobile phones, making them ideal for spaces where people spend extended periods-such as homes, offices, and hotel guest rooms-in alignment with healthy lighting trends.

2. Consistent Synchronous Startup

The soft-start series supports the synchronous power-up of multiple units, ensuring highly uniform lighting transitions without staggered activation. In applications such as large-scale circular LED strips or integrated ceiling lighting, this delivers a smooth, even illumination effect, significantly enhancing the sense of sophistication and visual cohesion within the space.
 

NFC-programmable soft-start capability is the core differentiator of this series. Full parameter configuration is achieved via smartphone NFC-without the need to disassemble the unit or connect it to power-enabling efficient and flexible lighting effect customization.

1. Customizable 0–99 Second Soft-Start Duration
Users can customize the power-on fade-in duration (0–99 seconds) via the companion app, creating a premium, hotel-grade soft-start effect. The lighting transitions smoothly from dim to bright, eliminating the glare caused by sudden, intense illumination-making it ideal for user-centric environments such as hotel guest rooms and high-end residences.

2. Precise Current and Brightness Adjustment
For constant-current versions, output current adjustment precision reaches 1mA; within the rated range, the driver flexibly matches various LED specifications, accommodating diverse lighting designs without requiring a power supply change. Constant-voltage versions support brightness settings from 25% to 100% and adjustable PWM frequencies (300–22,000 Hz), simultaneously meeting requirements for deep dimming and flicker-free performance.

3. Contactless Wireless Programming
All parameters are configured wirelessly via smartphone NFC, eliminating the need to open the power supply casing or connect to power for on-site commissioning. Technicians can batch-configure parameters in advance or make flexible adjustments based on on-site results after installation, effectively shortening construction timelines and boosting commissioning efficiency.
