Enclosed 108 W AT power supply

This Mean Well NES-100-24 is an enclosed AC-DC switching unit that delivers 108 W at 24 V and 4.5 A. It is built for equipment that requires a single regulated 24 V rail in an AT form factor.

Suits 24 V industrial or automation gear.

The supply suits machines, controllers or test rigs that need a steady 24 V 4.5 A source. It is not designed for desktop PC motherboards, GPU power or any load that expects ATX connectors or multiple voltage rails.

108 W continuous at 24 V

The unit provides up to 108 W continuously on the 24 V output, giving headroom for motors, sensors or PLCs drawing up to 4.5 A. Loads above 108 W or currents beyond 4.5 A will exceed its rating and require a larger supply.

Questions about this item

What AC input voltage range does the NES-100-24 require to operate?

The NES-100-24 is an AT type power supply designed for standard AC mains input. Ensure your local mains voltage matches the unit's rated input range before connecting it.

Can the NES-100-24 replace an older 12 V power supply in the same chassis?

No, the NES-100-24 delivers a fixed 24 V output at 4.5 A. It cannot power equipment that requires a 12 V rail, so verify your load voltage before swapping units.

How do I confirm the NES-100-24 is delivering its rated 108 W after installation?

Measure the output terminals with a multimeter under load; you should read approximately 24 V while the connected equipment draws up to 4.5 A, confirming the 108 W rating.
