MEAN WELL RD-125-1224 125W dvojvýstupný AC/DC napájací zdroj 12V 7A + 24V 2,5A

Industrial and automation systems often demand reliable DC power from two different voltage rails simultaneously, but combining separate power supplies adds cost, wiring complexity, and space. The MEAN WELL RD-125-1224 solves this by integrating a 12 VDC channel capable of 7 A and a 24 VDC channel at 2.5 A into one compact, chassis-mountable unit. With a total output of 125 W, it handles mixed loads such as motors, controllers, sensors, and communication modules without compromise.

Who is it for

This power supply is built for system integrators, machine builders, and maintenance engineers who need a dependable dual-voltage source inside control cabinets, CNC equipment, vending machines, or test rigs. It suits applications where both 12 V and 24 V devices must run from a single AC input, reducing inventory and simplifying installation.

Main features

• Dual isolated outputs: 12 VDC / 7 A and 24 VDC / 2.5 A, total 125 W continuous power.
• Wide AC input range 85–264 VAC (selectable) plus 240–370 VDC input for industrial flexibility.
• Built-in DC fan for forced-air cooling, ensuring stable operation up to +60 °C.
• Comprehensive protections: short circuit, overload, and over voltage on both outputs.
• Low ripple and noise: 120 mVp-p on 12 V, 150 mVp-p on 24 V.
• High isolation: 3 kVAC input-to-output, meeting UL60950-1 and TUV EN60950-1 safety standards.
• EMC compliance with EN55022 Class B for reduced electromagnetic interference.
• Chassis mount with screw terminals for secure wiring in industrial environments.

Tips

Always verify that the total load on each output does not exceed its rated current, and ensure adequate airflow around the unit when operating near the upper temperature limit. For best noise performance, use twisted pair wiring for output connections and keep input and output cables separated.
