iDrive Range Expands with Worlds First Variable Forward Current 350ma to 1A LED Driver

World leading LED driver manufacturer, IST Ltd, has expanded its range of innovative and cost competitive LED drivers with the world’s first variable forward current high power LED driver and its first single channel LED driver.

The new iDrive-1000 available in volume from July 2008 is a resilient 3-channel 210 Watt LED driver incorporating several patented power technologies to provide a passive (without the need for a cooling fan) small physical form factor LED driver capable of driving the latest generation of high power LEDs.

The feature packed iDrive-1000 is the world’s first LED driver to incorporate variable forward current options enabling users to choose any current between 350mA right up to 1000mA in 50mA steps independently on each of the three channels. For the first time, users can optimise the LED forward current on each channel according to the type of LED and the thermal capability of the fixture attached to the driver. This unique feature provides LED fixture manufacturers with a new ability to optimise the light output from fixture designs and maximise the light offering to their customers.

IST’s Global Sales Director, Matt Fitzpatrick, stated “We designed the iDrive-1000 to be the most powerful LED driver on the market but we also made it the most flexible with so many easy-to-use features to enable it to be used in almost any lighting system configuration. The response from our first customers have been incredibly positive as they realise how flexible the system is and initial customers have feedback that the iDrive-1000 has enabled them to get a XX% increase in light output by replacing their current driver solution with the iDrive-1000”.

The iDrive-1000 is the first driver in the iDrive range to incorporate the patented PowerSave technology that constantly monitors the forward voltage required by any LED fixture attached to the driver. In addition, the iDrive-1000 system can determine the voltage drop across the connecting cables and compensate to enable the driver to be replaced remotely from the fixture allowing extra installation flexibility.

Full closed loop feedback is employed to enable both driver and fixture thermal protection with up to 4 different settings enabling the user to determine maximum operating temperature giving a high degree of system protection in all environments.

In addition to the iDrive-1000, IST also launched it first single channel driver idea for single colour applications. The iDrive-025 is a 25W LED driver capable of driving LEDs at 350mA with total forward voltages between 30 and 72V DC and are perfect for white light LED applications. The high efficiency driver comes with a 3 year warranty.

The new drivers are both RoHS compliant and are available for volume orders from the beginning of July 2008.
