Power supply mean well RPS-120-24 120 W, 24 V output, 80–264 V input, RoHS, 50.8×101.6×29 mm

MEAN WELL RPS-120-24 is an open-frame medical AC-DC power supply providing 24 V DC at up to 3.5 A (120 W) from an 80–264 V AC input. The compact unit measures 50.8 × 101.6 × 29 mm (approximately 4 × 2 inches) and includes medical safety isolation rated for EN 60601 with 2×MOPP. It is RoHS compliant and designed for applications that require a small, reliable low-voltage medical-grade power source.

Advantages

The RPS-120-24 combines a high power density in a compact open-frame package with medical-grade isolation (EN 60601, 2×MOPP), wide input voltage range (80–264 V AC), and RoHS compliance. Its standardized 24 V DC output simplifies integration into equipment that uses common low-voltage rails, while the small footprint supports space-constrained installations.

Suitable for

• Medical devices and diagnostic equipment requiring EN 60601 isolation
• Embedded systems and industrial control cabinets with limited space
• Automation modules and instrumentation needing a stable 24 V supply

• Brand / MPN: MEAN WELL RPS-120-24

How to use

Mount the open-frame unit securely inside the equipment chassis with appropriate insulation and clearance per EN 60601 requirements. Connect the AC input to a properly fused mains source within the 80–264 V range and route the 24 V DC output to the device's low-voltage bus, observing correct polarity. Ensure earth grounding and follow the manufacturer’s installation instructions for creepage, clearance, and cooling to maintain safe operation.

Recommendations

Use the RPS-120-24 in indoor, controlled environments and follow EN 60601 installation guidelines: maintain required creepage/clearance distances, provide adequate ventilation, fuse the input appropriately, and verify grounding. Do not expose the open-frame supply to liquids or uncontrolled dust; if protection is needed, install within a suitable enclosed compartment.
