MEAN WELL RD-50A fonte de alimentação AC/DC de 54W com saída dupla 5V/6A + 12V/2A, entrada 88-264VAC, montagem em chassis, proteção contra sobrecarga/sobretensão/curto-circuito

The RD-50A stands apart from typical open-frame power supplies by combining two tightly regulated outputs in a compact, chassis-mountable package. With 5 V and 12 V rails delivering up to 54 W total, it eliminates the need for separate converters in mixed-voltage systems. Its universal AC input and wide operating temperature range make it a reliable choice for industrial control panels, automation equipment, and embedded electronics where space and dependability matter.

Highlights

• Dual output: +5 VDC (0.5–6 A) and +12 VDC (0.2–2 A) with combined 54 W maximum power
• Universal input voltage: 88–264 VAC (47–63 Hz) or 125–373 VDC, suitable for global use
• High efficiency up to 79% and 60 ms hold-up time at full load for stable operation
• Comprehensive protection: overload, overvoltage, and short circuit safeguards
• Free air convection cooling – no fan, silent and maintenance-free
• Wide operating temperature range: -25°C to +70°C
• Safety certifications: UL60950-1, TUV EN60950-1, CB, CE

In daily use

Installation is straightforward thanks to the chassis-mount design and screw terminal connections. The unit operates silently without forced air cooling, making it ideal for noise-sensitive environments. Its robust protection features guard against common electrical faults, reducing downtime and protecting downstream components. Whether powering microcontrollers, sensors, or small motors, the RD-50A delivers clean, stable DC output even under varying load conditions.
