This constant voltage LED driver provides a stable 48 V output and a maximum power capacity of 60 W, ensuring consistent electrical performance across a wide range of lighting systems. It supports dimming functionality via external PWM LED dimmers attached on the output side, allowing precise brightness control for various lighting moods and environments. The driver is suitable for luminaires of protection class I and II, offering flexibility in installation and compliance with multiple safety requirements. It can also be connected directly to on/off 48 V DC/DC boards, enhancing compatibility with modular or custom-configured LED systems. Each unit includes strain relief, and in the single-pack (SP) version, the driver is individually packaged for protection and ease of handling. Built for long-term reliability, it offers a nominal lifetime of up to 50,000 hours under standard operating conditions.
Compact and practical, the unit measures only 225 x 43 x 30.2 mm, allowing seamless integration in space-constrained areas such as cove installations, ceiling recesses, or architectural lighting enclosures. The design incorporates a stretched-compact strain relief for secure cable management, and push terminals simplify wiring during installation. Its low-frequency voltage ripple of less than ±1.5% ensures flicker-free performance, while standby power consumption remains below 0.5 W, supporting low-energy standby operation.
This driver is particularly well-suited for applications in cove lighting, façade accent lighting, and ceiling integration, where precise voltage regulation and compact form factor are critical. It can be paired effectively as a system solution with LLE FLEX SNC4 or EXC4 modules, and when used with ACL FLEX accessories, it supports direct wire-to-PCB connections for streamlined system configuration.
Electrically, the driver operates across a rated supply voltage of 220–240 V within an AC voltage range of 198–264 V at 50/60 Hz frequency. It includes integrated overvoltage protection rated for 320 V AC over 48 hours and maintains a typical input current of 290 mA at full load. Inrush current peaks at 32.3 A for 264 microseconds, and the driver achieves a typical efficiency of 91.5% at full load. Its power factor (λ) ranges from 0.8 to 0.98 across the operating range, while total harmonic distortion remains below 10%, ensuring minimal electrical interference. Start-up and turn-off times are both under 0.5 seconds, allowing immediate response during power cycling.
On the output side, the driver maintains a voltage tolerance of ±2 V, ensuring stable operation for sensitive LED modules. It also supports a low flicker metric (P_ST_LM ≤ 1) and a low stroboscopic visibility measure (SVM ≤ 0.4), meeting the latest performance standards for visual comfort. Surge protection is rated at 1 kV between line and neutral, and 2 kV between line/neutral and earth, with a 1 kV burst capability. The unit’s polycarbonate housing provides protection up to IP20, suitable for indoor use in controlled environments.
The driver operates effectively within ambient temperatures suitable for its 50,000-hour lifetime rating and can be safely stored between -40 °C and +80 °C. Its robust electrical and mechanical design ensures consistent performance in professional applications across architectural, commercial, and hospitality sectors. Supported by a five-year guarantee, this 48 V constant voltage LED driver combines compact construction, long service life, and stable electrical behavior to ensure dependable operation in both decorative and functional LED lighting systems.
