Power Adapter MEAN WELL RD-85A 85W Input 88-264V Output 5V

The MEAN WELL RD-85A is an enclosed AC-DC dual-output power adapter designed for stable low-voltage supply. It accepts a wide input range of 88–264 VAC and delivers a combined output of up to 85 W: 5 V DC at 10 A and 12 V DC at 5 A. The compact unit (97 × 159 × 38 mm) uses free-air convection cooling and carries RoHS compliance for reduced environmental impact.

Advantages

The RD-85A offers dual isolated outputs with clear current allocation, a wide universal input voltage for global compatibility, compact dimensions for space-constrained installations, and convection cooling that eliminates the need for a fan. RoHS conformity ensures it meets basic environmental and safety restrictions for lead and hazardous substances.

Suitable for

• Embedded systems and industrial control equipment
• Network devices and peripherals requiring 5 V and 12 V rails
• Point-of-sale terminals and compact electronic enclosures

How to use

Install the RD-85A in a well-ventilated enclosure or on a flat surface that allows free airflow around the housing. Connect the AC input to a suitable mains source within 88–264 VAC, observing correct wiring and grounding. Connect the 5 V and 12 V output terminals to the loads, ensuring the current draw does not exceed 10 A on the 5 V rail and 5 A on the 12 V rail. Verify polarity and secure terminal connections before powering the unit.

Recommendations

Use the power adapter within its specified input and output ratings, avoid obstructing ventilation, and allow adequate spacing from heat-sensitive components; for long-term reliability, operate the unit below maximum rated ambient temperature and avoid sustained full-load operation in poorly ventilated locations.
