DC/DC LED Drivers Launched By Powerpax UK

Powerpax UK has announced the launch of the PLC24AH range of dimmable, constant current, DC/DC LED drivers. The PLC24AH series provide a step-down constant current source for driving high-brightness LEDs. Standard output currents include 300mA, 350mA, 500mA, 600mA and 700mA, making these drivers compatible with a range of LEDs and applications. The output voltage range for these drivers is 2-32VDC and all models feature continuous short-circuit protection. These products have a compact size and operate without the need for external components.

They provide a high-efficiency solution (up to 95 per cent) for LED driving in both standard and dimming applications. Dimming is achieved through use of an industry standard PWM method - the PWM input is specified to operate between 0.2-10Khz. If dimming is not required, the PWM input doubles as a remote On/Off input. This series has an operating temperature range of -40C to +71C (minimum). These drivers are compact and feature a case size of 22.8 x 10.2 x 9.5mm with a weight of 3.5g.

The case is manufactured from a UL94-V0 rated plastic and these parts conform to RoHS requirements. The series is designed to be as reliable as the LEDs it will drive, and the MTBF for these drivers is two million hours (calculated to MIL-HDBK-217F at 25C). In addition to this range of DC/DC LED drivers, Powerpax also offers a range of AC/DC LED drivers, including standard dimming and waterproof driver products.
