IST Launches the World’s Highest Power DALI Driver: iDrive White Knight 32

Mar 19, 2011 IST Ltd has launched the iDrive White Knight, the world’s highest powered 32 channel DALI LED driver, which boasts a super slim 1U 19” rack-mounted chassis. Designed specifically for the demanding professional white light market, the White Knight 32 offers unprecedented step-less dimming capabilities down to <1% independently on each of the 32 channel outputs. The White Knight can be configured to drive up to 512 LEDs from 672W of output power.

The new iDrive® White Knight offers one of the most complete DALI ballasts available and implements over 90 DALI commands from the official DALI BS EN 62386:2009 standard, including Part 101 and the extended Part 107 DALI commands, which relates specifically to LED ballasts.

Additional features of the White Knight include real time LED current and voltage feedback, Universal Input Mains voltage between 110-240V AC as well as providing high efficiency LED output stages (>98%).

At the core of the White Knight is the Texas Instruments 32-bit Digital Signal Processor with high performance embedded DALI software. The eco-DSP platform enables the installer to programme each channel for LED currents up to 1A per channel and Vf voltages up to 48V. Channels can also be bonded together, enabling simple optimization of fixtures designed with LED arrays such as Bridgelux, Sharp and Citizen, as well as bespoke light engines designed with OSRAM, CREE, Seoul Semi and Philips Lumileds products.

The White Knight 32 will be available as engineering samples during April, with volume production from end May 2011.
