The constant voltage LED driver represents a robust and reliable power solution developed for professional and architectural lighting applications that demand consistent 24V DC output and superior performance stability. Operating across a universal input voltage range from 120 to 277 volts AC, this driver supports both 50 and 60 Hz mains frequencies, ensuring full compatibility with a wide variety of global electrical infrastructures. As a UL Listed Class P and Class 2 device with Type HL certification, it meets the highest safety and performance standards required for dry and damp locations, making it suitable for use in a broad range of commercial, retail, and general indoor installations. The driver achieves a maximum output power of 99.6 watts and sustains a nominal lifetime of up to 50,000 hours at 45°C, supporting long-term reliability and reduced maintenance intervals across demanding applications.
Constructed with a durable metal housing in a clean white finish, the driver maintains mechanical integrity while optimizing thermal dissipation to protect internal components and maintain electrical efficiency. Its IP20-rated casing makes it ideal for controlled indoor environments, while its tinned single-wire terminations ensure secure electrical connections and simplified fixture integration. The inclusion of 0–10 V dimming capability allows precise brightness control, supporting a wide range of dimming systems to enhance visual comfort and energy optimization across different lighting scenes.
Comprehensive electronic protection mechanisms are built into the driver to ensure stable operation and fixture longevity. These include overtemperature, overload, short-circuit, and no-load protections, safeguarding both the driver and the connected LEDs from electrical faults or irregular conditions. The driver’s operational resilience is further reinforced by its compliance with FCC Part 15 Class B standards, ensuring low electromagnetic interference and seamless operation within complex electrical environments.
Electrical performance metrics highlight the driver’s precision and efficiency. At 277 V and full load, the unit draws approximately 450 mA, while at 120 V, it operates at 950 mA, achieving efficiencies greater than 90% and 88%, respectively. The driver maintains total harmonic distortion (THD) below 20% at 277 V and below 10% at 120 V, ensuring clean power output and system stability. In no-load operation, input current remains low—37 mA at 277 V and 50 mA at 120 V—while standby power consumption stays below 0.5 W and 0.7 W, minimizing energy waste when the driver is idle.
Startup and operational timing further reflect the unit’s efficiency and precision. The start time for output activation is less than 0.5 seconds, with an extremely fast turn-off time of 0.01 seconds and a hold time during power failure below 0.001 seconds, ensuring immediate responsiveness in dynamic lighting environments. The output voltage tolerance of 23.5 to 24.5 volts guarantees constant voltage delivery to connected LED modules, maintaining brightness consistency and color stability. In addition, output ripple is maintained under 4.2%, with flicker performance indices (P_ST_LM ≤ 1 and SVM ≤ 0.4) confirming flicker-free operation even under full load conditions.
Electrical robustness is reinforced through strong surge and transient protection capabilities. The driver withstands 2 kV between line and neutral (L–N), 4 kV between line/neutral and protective earth (L/N–PE), and 1 kV burst surges, along with < 0.5 kV protection on the output side, ensuring durable operation under fluctuating mains conditions. The driver is capable of enduring storage temperatures between -40°C and +85°C, ensuring reliability during transportation and installation across diverse environments.
Overall, this constant voltage LED driver serves as a dependable and efficient power control component for LED lighting systems requiring stable 24V DC operation, wide input voltage compatibility, smooth dimming, and robust protection in professional-grade environments. Supported by a 5-year guarantee, it represents a long-term solution for lighting manufacturers, system integrators, and contractors seeking consistent output quality and assured compliance across commercial, architectural, and general lighting projects.
