Voeding MEAN WELL DRA-40-24

The MEAN WELL DRA-40-24 is an AC-DC industrial DIN-rail power supply that delivers 24 V DC at up to 1.7 A (40 W). It accepts a wide input voltage range of 90–264 VAC and is RoHS compliant. Housed in a compact plastic case designed for DIN-rail mounting, this adapter is intended for control cabinets and industrial automation where a stable 24 V supply is required.

Advantages

The unit provides a regulated 24 V output with up to 40 W of power in a compact DIN-rail form factor. Wide input range (90–264 VAC) allows installation in diverse mains environments. The plastic enclosure is lightweight and suitable for standard industrial mounting; RoHS compliance ensures reduced hazardous substance content. The model includes a dimming control option compatible with 0–10 V DC PWM/resistive dimming interfaces.

Suitable for

• Control panels and automation equipment requiring 24 V DC
• LED drivers and lighting systems using 0–10 V dimming
• Instrumentation and sensors in industrial installations
• Machine control modules and relay panels

How to use

Mount the power supply on a compatible DIN rail inside the control cabinet. Connect the AC input (90–264 VAC) to the designated L and N terminals and connect the 24 V DC output to the load, observing correct polarity. If dimming is required, connect a 0–10 V DC PWM or resistive dimming control to the designated dimming terminals according to the system wiring diagram. Ensure adequate ventilation and follow local electrical codes during installation.

Recommendations

For reliable operation, keep ambient temperature within the manufacturer's specified range and avoid installation near heat sources. Use proper fusing on the AC input and verify load does not exceed the 1.7 A rating. For large installations, consider the packaged quantity (42 units) for procurement planning.
