Power adapter MEAN WELL RPT-75B 75W 12V 90-264V

The MEAN WELL RPT-75B is an open-frame AC-DC medical power supply providing three outputs: 5 V DC at 8 A, +12 V DC at 4 A and -12 V DC at 1 A. It accepts an input voltage range of 90–264 V AC and delivers up to 75 W total output power in a compact housing measuring approximately 76.2 mm × 127 mm × 31 mm. The unit is designed to meet medical safety isolation requirements with two MOPP and is RoHS compliant.

Advantages

The RPT-75B offers multiple regulated outputs in a single open-frame module, allowing use in medical equipment that requires both positive and negative rails plus a higher-current 5 V supply. Its wide input voltage range supports global mains voltages, and the compact footprint makes it suitable for space-constrained system designs. Two MOPP-rated isolation provides enhanced patient-applied part safety for medical applications.

Suitable for

• Medical devices requiring multiple DC rails and medical-grade isolation
• Embedded systems and instrumentation with space limitations
• Equipment needing a stable 5 V supply alongside ±12 V rails

Key specifications

• Total output power: 75 W
• Outputs: 5 V DC at 8 A; +12 V DC at 4 A; -12 V DC at 1 A
• Input voltage: 90–264 V AC
• Isolation: two MOPP (medical isolation)
• Dimensions (W×D×H): approximately 76.2 mm × 127 mm × 31 mm
• Compliance: RoHS

How to use

Integrate the RPT-75B into your device according to the equipment’s mechanical mounting and electrical wiring requirements. Connect the AC mains within the specified 90–264 V range and route the DC outputs to the respective loads, observing polarity and current limits for each rail. Ensure the unit is installed in an enclosure or layout that maintains required creepage and clearance distances for medical isolation and provides adequate ventilation for heat dissipation.

Recommendations

Install following applicable medical safety standards and the manufacturer's mechanical and electrical instructions. Verify output voltages under load and avoid exceeding per-rail current ratings; provide appropriate filtering and transient protection at the system level when needed.
