This Boke constant current LED driver combines DALI-2 and 1-10V/PWM dimming in one unit, built for LED fittings that need a separate driver rather than a built-in one. It runs at a maximum current of 1100mA and is identified by the model code BK-DUL042-B1100ADF. Adjustable current settings let you match the driver's output to the LED chip it is feeding, which keeps the chip running at the right ampere rating and supports a longer life expectancy.

Key features of this constant current LED driver

• Dimming protocols, DALI-2+PUSH+1-10V/10V PWM dimming mode supported
• Current output, 10-level current output set via DIP-switch, max 1100mA
• Dimming range, 1~100% with output current accuracy of 1%
• Standby power, input under 0.5W, meeting ErP certification requirements
• Lifetime, nominal lifetime up to 100,000h, backed by a 5-year guarantee
• Protection grade, IP20, for indoor use

Interfaces and functions

The driver offers DALI-2 (DALI-2 DT6), PUSH (PUSH-DIM with corridor function) and DIM (1-10V/10V PWM) interfaces. It supports central emergency applications with normal dimming on DC input, as well as self-contained emergency applications. Built-in protective features cover short-circuit, no-load and hot plug-in protection, alongside intelligent LED hot-plug protection.

Design and construction

Screw-free, pressing-type strain relief accommodates thicker cables and speeds up installation, with independent input and output strain relief for stronger wiring. The unit uses SELV and Class II design, suitable for use outside the light fitting itself, and carries HPC patented technology so brightness stays consistent between fittings at any dimming level. High power factor, high efficiency and low THD are also specified.

Suitable applications

Suited to lights with independent drivers such as downlights, spotlights and panel lights; not suitable for fittings with built-in drivers. Typical uses include LED indoor lighting, LED office lighting and LED commercial lighting. The driver has passed ENEC-TUV, CE, RCM, CCC, DALI-2 and other certifications.
