The ALD drivers are designed to operate with an input voltage of from 10.8 to 13.2VDC and have a maximum open-circuit output voltage of 42 to 44VDC. The series are ultra thin (5.0 to 5.5mm) to facilitate easy mounting behind LCD screens with a minimum of space. The 2 and 3 string models measure only 21.5mm high by 85mm long and the 4 string drivers are 50mm high by 100mm long.
Other features include a Remote On/Off input and an Overvoltage Alarm output.
The Overvoltage Alarm serves as a LED open detector. These drivers are convection cooled and designed to operate in ambient temperatures from ranging from -30°C to +85°C without deratings. Typical operating efficiencies are 90%, which substantially reduces power con-sumption and unwanted heat.
The ALD Series are ideal for backlighting of LCD panels used in vending machines, industrial touch screens, POS terminals and programmable controllers, to name a few. This series is available now and priced at $18.75 in 1000 piece quantities. Detailed specifications are available at the following web link: http://www.us.tdk-lambda.com/lp/products/ald-series.htm
