This constant current LED driver is purpose-built for professional lighting applications across the United States, ensuring consistent power regulation and long-term reliability. Supporting dimming control through a 0–10 V interface, it enables smooth light adjustment across a range of 10% to 100%, providing flexibility for both architectural and commercial lighting systems. Classified as Class 2, it meets DesignLights Consortium (DLC) 4.3 standards and is certified as UL Listed Class P, ensuring compliance with key U.S. safety and performance regulations. The driver offers selectable output currents of 1,360 or 1,450 mA, with a maximum output power of 58 watts, making it suitable for a wide variety of constant current LED modules. With a nominal lifetime of up to 50,000 hours, it supports reliable, long-term lighting operation under demanding conditions.
The driver is housed in a low-profile, white metal casing with IP20 protection, ideal for installation in dry and damp locations. Its compact and durable construction allows for flexible integration into luminaires and system enclosures. Multiple layers of electronic protection are incorporated, including overload, short-circuit, no-load, and overtemperature safeguards, which help maintain both driver and luminaire integrity throughout their service life.
Operating within a wide rated supply voltage of 120 to 277 V AC, and an extended range from 108 to 305 V, the driver performs efficiently at 50 or 60 Hz mains frequency. At full load, its efficiency reaches 88% at 277 V and 86% at 120 V, supported by a high power factor of 0.95 across both voltages. Total harmonic distortion remains below 20%, ensuring stable and low-noise operation compatible with sensitive electronic environments. The driver draws minimal current in no-load operation—only 24 mA at 277 V or 15 mA at 120 V—and consumes less than half a watt of input power in standby mode, optimizing energy use during idle periods.
In-rush currents are limited to 12.5 A for 23 microseconds at 277 V and 4.2 A for 31 microseconds at 120 V, preventing stress on upstream electrical components. The driver maintains fast response performance, with a start time of less than 0.5 seconds and an equally short turn-off time, while its power-hold time during outages reaches 0.01 seconds. The output current remains stable within a ±5% tolerance, with non-repetitive peaks restricted to 15% above the nominal value. Ripple current is controlled within ±15% below 120 Hz, supporting consistent LED brightness and flicker-free operation. The driver’s output voltage is limited to a maximum of 60 V to protect connected LED loads.
Electrical robustness is reinforced by multiple surge protection layers: 2 kV between line and neutral, 2 kV between line/neutral and protective earth, and 3 kV at the output side, supplemented by 2.5 kV surge ring wave protection. These specifications ensure strong resistance to transient events and power surges, particularly in commercial and industrial electrical environments.
Measuring 280 mm in length, 30 mm in width, and 21 mm in height, the unit’s compact design simplifies installation within lighting housings and retrofit systems. With a service lifetime reaching 50,000 hours and backed by a five-year guarantee, this constant current LED driver offers a dependable foundation for long-lasting, dimmable lighting solutions across professional, retail, and architectural applications.
