DFX1512A

Product catalog summary

Overview: The DFX1512A is a power supply unit designed for industrial and residential applications, offering a wide input range and flexible power continuity up to 20 W. It features overload, overvoltage, and short-circuit protection, and can be mounted on DIN rails or walls.

Specifications:

Input: Nominal voltage of 100 – 240 – 277 Vac, with an AC input range of 85 – 305 Vac and DC input range of 95 – 370 Vdc. It operates at an AC frequency of 45 – 65 Hz and has a current consumption of approximately 0.3 A at 120 Vac and 0.2 A at 230 Vac.
Output: Provides an isolated DC voltage of 12 Vdc ± 3%, with an adjustment range of 10.5 – 14.5 Vdc. It supports a continuous current of 1.2 A up to 55°C, with derating above this temperature.
Efficiency: Approximately 80% efficiency at rated output, with a power loss of 2.8 W at rated output and 0.3 W during no-load operation.

Protection and Monitoring: Features include over-temperature protection, short-circuit protection, and over-voltage output protection. A green LED indicates status output voltage OK.

Environmental Conditions: Operates in ambient temperatures from -25 to +70°C and can be stored between -40 to +85°C. It is designed to withstand vibrations and shocks as per IEC standards.

Safety and Certifications: The unit provides primary/secondary isolation and complies with various safety and environmental standards, including CE, EMC, and RoHS directives. It is pending UL/cUL approval.

Mechanical Data: The unit features screw-type connections and is housed in polycarbonate material, with dimensions of 18 x 90 x 55 mm and a weight of approximately 0.1 kg.
