Power adapter/inverter MEAN WELL RID-125-1224, 125 W, 12 V output, 176–264 V input

MEAN WELL RID-125-1224 is an enclosed AC-DC dual-output power supply delivering 12 V DC at 7 A and 24 V DC at 5 A with isolated outputs. The unit accepts a wide AC input range of 176–264 V and provides 125 W total output power in a compact housing (98 × 199 × 38 mm). The design uses free-air convection for cooling and complies with RoHS requirements, making it suitable for installations where space and ventilation are limited.

Advantages

The RID-125-1224 offers two isolated outputs for simultaneous 12 V and 24 V loads, a wide AC input range (176–264 V) for flexible mains compatibility, and a compact form factor for space-constrained installations. Free-air convection cooling eliminates the need for fans, reducing moving parts and maintenance. RoHS compliance ensures alignment with environmental standards.

Suitable for

• Powering 12 V devices and accessories
• Supplying 24 V control circuits and sensors
• Industrial control equipment and automation panels
• LED lighting systems and signage
• Backup power modules and auxiliary power in cabinets

How to use

Install the RID-125-1224 in a well-ventilated location with adequate clearance for natural convection. Connect the AC mains within the specified 176–264 V range and wire the 12 V and 24 V outputs to the respective loads, observing correct polarity. Ensure the outputs remain within rated current limits (7 A for 12 V, 5 A for 24 V) and follow local electrical codes when making connections. Mount the unit according to the manufacturer's instructions and secure all terminals before powering on.

Recommendations

For reliable operation, avoid enclosing the power supply in tight, poorly ventilated housings and do not exceed the rated output currents. Use appropriate fusing on input and output lines and verify compatibility of connected devices with the 12 V and 24 V outputs. Store and operate within manufacturer-specified temperature and humidity ranges.
