Napajanje MEAN WELL DDR-120A-24

MEAN WELL DDR-120A-24 is an ultra-slim industrial DIN-rail DC-DC converter delivering a single 24Vdc output at up to 4.2A from a 9–18Vdc input. The unit provides 120W of continuous power in a compact housing (32 mm W × 102 mm D × 125.2 mm H) and meets RoHS requirements, making it suitable for space-constrained installations that require regulated 24V power.

Advantages

The slim DIN-rail form factor allows installation in narrow control cabinets and crowded rail systems. With 120W output capacity and regulated 24Vdc at 4.2A, the converter supports a range of industrial loads. Compliance with RoHS ensures reduced hazardous substances. The model DDR-120A-24 is designed for reliable continuous operation and is available in multi-unit packs for deployment at scale.

Suitable for

• Industrial control cabinets and automation panels
• Rail-mounted power distribution in machinery and equipment
• Embedded systems requiring 24Vdc from 9–18V input sources
• Bulk deployments where multiple identical power modules are needed

How to use

Mount the DDR-120A-24 onto a standard DIN rail and secure mechanical connections according to panel layout. Connect the input to a suitable 9–18Vdc source observing correct polarity, and wire the 24Vdc output to the load using appropriately rated conductors. Verify connections and power on the input supply; monitor output voltage and load current to ensure operation within rated limits.

Recommendations

Install the unit in a ventilated enclosure and avoid mounting near heat sources. Use proper fusing on the input side and ensure wiring meets local electrical codes. For bulk installations, plan accessible routing for input and output terminals to simplify maintenance.
