40 W 12 V power adapter for CWT units

This 40 W adapter delivers 12 V at 3.33 A through a 5.5 x 2.5 mm barrel connector. It replaces the KPL-040F-VI or KPL-040F unit used with compatible CWT power supplies. The package includes the adapter and a mains lead. It is intended for users who need a direct replacement for a lost or damaged original charger.

Works with 100–240 V 50–60 Hz mains worldwide

The adapter accepts a wide input range so it can be used with EU, US, UK or AU plug types without a separate voltage selector. A single IEC power cord connects the brick to the wall outlet. This removes the need to source a region-specific power supply. The barrel plug fits devices that require the 5.5 mm outer and 2.5 mm inner dimensions.

Continuous 40 W output under sustained load

The unit is rated to supply its full 40 W continuously while maintaining the 12 V rail within specification. CE certification confirms compliance with relevant safety and electromagnetic standards. It is not suitable for equipment that draws more than 3.33 A or requires a different voltage. Buyers needing higher wattage or a different connector size should look elsewhere.

Questions about this item

How much current can the 12 V output deliver continuously?

The adapter is rated for 3.33 A at 12 V, giving a maximum continuous output of 40 W.

Does the brick get hot or noisy when left on 24/7?

It is a passively cooled wall-wart with no fan, so it runs silently; the case will become warm under full load but stays within normal operating temperature.

Which mains plug do I need to have on hand for the included power cord?

The package ships with a detachable IEC C7 lead; you must supply the matching EU, US, UK or AU mains plug for your region.
