The constant voltage LED driver is a robust and efficient power solution built for universal applications across a wide input voltage range. It operates within a universal AC input of 120 to 277 volts and maintains reliable functionality between 108 and 305 volts, making it highly adaptable to global electrical standards. This driver supports a maximum output power of 60 watts and maintains consistent voltage control between 22.8 and 25.2 volts, ensuring optimal performance for compatible LED systems. As a Class 2 and Type HL device, it meets stringent safety and reliability standards, while also carrying UL Listed Class P and FCC Part 15 certifications for electromagnetic compliance. Its nominal lifetime extends up to 50,000 hours at an ambient temperature of 45°C, ensuring long-term dependability in a variety of lighting applications.
Constructed with a durable white metal casing, the driver is suitable for use in both dry and damp locations, providing versatility for indoor or protected outdoor installations. It incorporates multiple layers of electronic protection, including overtemperature, overload, short-circuit, and no-load safeguards, ensuring the system remains safe under all operational conditions. This advanced protection circuitry allows the driver to operate efficiently even during fluctuating loads or transient power conditions.
Performance characteristics demonstrate exceptional efficiency and stability. The driver achieves over 90.5% efficiency at 277 volts and more than 88% efficiency at 120 volts, minimizing power loss and heat generation. It exhibits low leakage currents—below 0.3 mA at both 230 and 120 volts—enhancing operational safety and compliance with international standards. Startup behavior is rapid and reliable, with a typical output activation time of less than 0.5 seconds, while shutdown occurs almost instantaneously, within 0.01 seconds. During a power failure, the output hold-on time remains below 0.001 seconds, ensuring no unintended flicker or delay upon power restoration.
Electrical performance is further optimized through low-frequency voltage ripple control of less than 2.1%, ensuring stable LED output without visible flicker. The driver also maintains a P_ST_LM flicker index of ≤1 and an SVM (Stroboscopic Visibility Measure) of ≤0.4, aligning with stringent visual comfort and performance requirements. Built to withstand electrical disturbances, it provides strong surge and burst immunity, handling up to 2 kV between live and neutral, 4 kV between live/neutral and ground, and up to 1 kV burst capability between live and neutral. At the output side, surge voltages remain below 0.5 kV, offering additional protection for connected LED modules.
Operating reliably across a wide storage temperature range of -40°C to 85°C, this LED driver demonstrates resilience in diverse environmental conditions. Its IP20-rated metal housing enhances both thermal performance and safety in controlled environments. With a five-year guarantee, the constant voltage LED driver represents a dependable, efficient, and safety-certified solution for professional LED systems that demand stable power delivery, low ripple performance, and long service life.
