Product information

Description

The MEAN WELL DRA-40-12 is an AC-DC industrial DIN-rail power supply that delivers 12V DC at up to 3.34A (40W). It accepts a wide input voltage range of 90–264V AC and comes in a compact plastic enclosure sized 40mm (W) × 100mm (D) × 90mm (H). The unit complies with RoHS requirements and is intended for applications that need a stable 12V DC rail on DIN mounting.

Advantages

This DIN-rail power supply provides a stable 12V output with 40W total power and supports dimming control via 0–10V DC / PWM / resistance input. Its wide AC input range allows use in international mains systems, while the compact plastic case and DIN-rail mounting save panel space and simplify installation. RoHS compliance ensures adherence to environmental safety standards.

Suitable for

  • Industrial control cabinets and automation systems
  • LED lighting drivers and dimming circuits using 0–10V or PWM control
  • Embedded electronics and small appliances requiring 12V DC
  • Field installations where DIN-rail mounting is required

How to use

Mount the power supply on a standard DIN rail and connect the AC input to a correctly rated mains supply within 90–264V AC. Connect the 12V DC output to the load ensuring the combined current does not exceed 3.34A.
