Born to drive high-brightness LEDs, the LDF24E series LED drivers operate from a wide input-voltage range and provide constant current outputs of 300 mA, 350 mA, 500 mA, 600 mA, or 700 mA. They feature analog and PWM dimming while achieving an efficiency up to 96%. Other features include short circuit protection, a MTBF per MIL HDBK 217F greater than two-million hours, and cooling via free-air convection. MICROPOWER DIRECT, Stoughton, MA. (781) 344-8226.
