DUALdrive AC, a 100W Dual-Channel Mains LED Driver/Controller

DUALdrive AC Series
DUALdrive is an integrated AC mains, constant current driver/ controller, which is targeted at high-power, general white LED lighting applications. DUALdrive is DALI (Colour) compatible, but can also be used as a standalone device. It offers a 20-bit resolution and a gamma-corrected dimming curve.

Application area: dual-channel white LED lighting
DUALdrive�s two control channels allow you to set colour temperature and brightness in tunable white applications, or to separately balance ambient and task lighting in two control channel, white lighting luminaires. DUALdrive is DALI (Colour) and switch-dim compatible. DALI is ideal for larger, flexible networked installations. In smaller (standalone) applications, you can use switch-dim. For switchdim, DUALdrive must be connected to a momentary light switch. Pressing the switch turns the light on or off, pressing it and holding it down lets you set the dimming level. Further advantages of switch-dim include multiple control points, soft start and return to last setpoint.

Dimming and colour temperature control
DUALdrive supports a wide dimming range of 100% down to 0.1% and a gamma corrected dimming curve. The gamma correction combined with high resolution results in eye sensitivity adjusted, smooth and flicker free dimming of high-power LED luminaires. DUALdrive also allows accurate control of colour temperature, which has been proven to have a profound effect on our sense of wellbeing.

Suitable for practically all LED types
The available LED output current on DUALdrive ranges from 200mA up to 1,050mA in 50mA steps, making it the perfect match for practically every light engine and configuration.

LEDcode interface
DUALdrive is LEDcode compatible, meaning you can finetune LED output current settings for your LED application over the LEDcode connectors. The LEDcode connectors can also be used to connect an NTC thermistor. An NTC thermistor provides temperature feedback and ensures that normal LED operating temperatures are maintained.
