The MicroPower DirectLDC-240 series of ac/dc LED drivers provide the constant current output, high efficiency, wide ac-input range, and rugged packaging required for industrial lighting systems. All models of the LDC-240 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°C to 70°C ambient. Cooling is by free-air convection. The LDC-240 series of LED drivers suit a wide variety of applications featuring LED lamps. The drivers provide the stable constant output current, analog and digital controls, output power, output voltage range, and rugged packaging required to effectively power industrial/commercial lighting systems. Other models are available ranging from 60 W to 200 W, including “lamp base” units.
Seven models of the LDC-240 LED drivers operate from a universal 90- to 305-Vac input and provide constant current outputs ranging from 0.70 to 7.00 A at corresponding output voltage levels of 18 to 400 Vdc. Standard features include 94% efficiency, active PFC, 10-kV surge protection, short-circuit protection, and an analog or PWM dimming control input. The MTBF (per MIL HDBK 217F) for series is greater than 220 kh. All models are UL 8750-approved and meet the requirements of EN 55015 and EN 61547.
The products are designed to provide long, reliable field life. Considerable attention is given to the proper selection, derating, and layout of all circuit components. In addition, extensive reliability screening is also performed on all modules as a routine part of our production process.
