Compact, constant current LED power supply suits industrial use

The LDC-185 series of ac/dc LED drivers provide a constant current output, high efficiency, ac-input and rugged packaging needed for industrial lighting systems. Eight models operate from 90 to 305 Vac input and provide constant current outputs ranging from 0.50 to 5.25 A at corresponding output voltage levels of 25 to 400 Vdc.

Standard features for the LED power supplies include 92% efficiency, active PFC, 10-kV surge protection, short circuit protection, and an analog or PWM dimming control input. The MTBF (per MIL HDBK 217F) of the LDC-185 series is greater than 220 kh. All models are UL 8750 approved and meet the requirements of EN 55015 and EN 61547. All models of the LDC-185 family are packaged in aluminum cases rated to IP65 or IP67 dust and moisture ingress protection. They are specified for operation over the industrial operating temperature range of –40° to +70°C ambient.
