Power adapter MEAN WELL GST120A24-R7B 120 W, 24 V, AC input 85–264 V, RoHS, 67×167×35 mm

MEAN WELL GST120A24-R7B is a compact AC‑DC power adapter that delivers 24 V DC at up to 5 A from a wide AC input range of 85–264 V. With a rated output power of 120 W and built‑in power factor correction (PFC), this adapter is intended for reliable low‑voltage power delivery in industrial and commercial electronic equipment. The unit conforms to RoHS requirements and is supplied in packs suitable for installations and system deployments. Its compact enclosure measures 67 × 167 × 35 mm and includes a three‑pole IEC320‑C14 AC inlet for secure mains connection.

Advantages

The adapter combines a compact footprint with a high 120 W output, enabling space‑efficient installations without compromising power. Integrated PFC improves mains compatibility and reduces input current distortion. Broad AC input compatibility allows use in regions with different supply voltages while RoHS compliance supports environmentally conscious deployments. The sealed desktop/industrial housing provides a practical balance between cooling and protection for routine operational environments.

Suitable for

• Powering industrial control modules, sensors and small PLCs
• Supplying commercial electronics such as signage, routers and network devices
• Use in test benches, repair stations and equipment racks
• Batch deployments and system installations that require multiple identical adapters

How to use

Connect the adapter to a compatible AC mains supply using a correctly rated IEC power cable and confirm the supply voltage is within the 85–264 V range. Attach the DC output to the device requiring 24 V, observing correct polarity and secure wiring or connector attachment. Allow adequate ventilation around the enclosure during operation and mount or place the unit on a stable surface. Follow the powered device manufacturer’s guidelines for inrush current and startup sequencing to avoid overload conditions.

Recommendations

For best performance, use the adapter in environments within the specified ambient temperature and humidity ranges, ensure wiring and connectors are sized for the 5 A output, and provide clearance for airflow. When deploying multiple units, inspect each adapter for physical integrity before installation and verify DC output voltage under load. For applications requiring additional protection, consider using upstream surge protection or fusing to protect against mains disturbances.
