120 W 24 V desktop power adapter

This Mean Well GST120A24 adapter delivers 24 V at 5 A for a total of 120 W. It suits equipment that requires a regulated 24 V supply, such as industrial controllers, LED lighting systems or portable test gear. The unit accepts a universal 100-240 V input at 50 or 60 Hz.

Barrel-plug installation with included cord

The adapter terminates in a 5.5 mm by 2.5 mm barrel connector and ships with a detachable mains lead. Connection is a simple push-fit; ensure the jack polarity matches the device before powering on. Overseas purchases may not include the power cord, so verify local cable availability. The housing may show minor cosmetic marks that do not affect operation.

Check voltage, current and connector fit

Confirm the target device specifies exactly 24 V input and draws no more than 5 A. Verify the device uses a 5.5 mm by 2.5 mm centre-positive barrel jack; a different size or polarity will not work. Ensure the installation environment can accommodate the adapter’s operating temperature range and that the mains supply falls within the 100-240 V range.

Questions about this item

How do I verify the GST120A24 is delivering 24V 5A after connecting it?

Measure the output with a multimeter set to DC volts; it should read close to 24 V under load, and the connected device should operate normally without unexpected shutdowns.

What comes with the GST120A24-P1M and what must I source separately?

The adapter includes a detachable power cord for 100-240 V~ 50/60 Hz mains; the 5.5 × 2.5 mm DC plug is fixed to the unit, so no extra cable is needed for the output side.

Which GST120A24 version suits a device rated for 120 W at 24 V?

This single 120 W model provides 24 V at 5 A, matching a 120 W load exactly; choose it when your equipment specifies 24 V input and draws up to 5 A.
