24V 2A AC-DC Power Supply, 2.1 x 5.5mm Center Positive | SW-242T9
SW-242T9 24V 2A AC-DC Switching Regulated Power Supply converts 100–240V AC input to regulated 24V DC output at up to 2A, or 48W maximum. Its wall-mount design and 2.1 x 5.5mm center-positive barrel plug provide a straightforward power source for compatible 24V DC equipment.
Important: Confirm the equipment voltage, current requirement, connector dimensions, barrel length, and polarity before connecting. This supply is for compatible 24V DC applications and should not be used with 5V, 9V, 12V, or other lower-voltage equipment.

Common Applications
- Power compatible 24V DC LED lighting, light strips, sign modules, and display equipment.
- Supply compatible security, monitoring, networking, control, and sensor equipment that specifies 24V DC and the matching barrel connector.
- Provide regulated 24V DC power for compatible electronics, automation accessories, test fixtures, and hobby projects.
- Use as a replacement for a compatible 24V AC-DC adapter when the electrical and connector specifications match exactly.
Compatibility Notes
- Confirm the device requires 24V DC, not 5V, 9V, 12V, or another voltage.
- Keep the equipment demand at or below 2A and 48W. A device draws only the current it requires when the voltage and connection are correct.
- Verify the device accepts a 2.1mm inside diameter x 5.5mm outside diameter plug and that the 11mm barrel length fits its jack.
- Confirm center-positive polarity before connection. Matching connector dimensions alone do not prove compatibility.
- Do not connect the DC output to AC equipment or use this adapter where a different voltage, polarity, or connector is specified.
Frequently Asked Questions
What output does the SW-242T9 provide?
It provides regulated 24V DC output at up to 2A, for a maximum calculated output of 48W.
What is the input voltage range?
The listed input range is 100–240V AC. Confirm the installation and receptacle requirements for the intended location.
What plug does this power supply use?
It uses a 2.1mm inside diameter x 5.5mm outside diameter center-positive barrel plug with an 11mm barrel length.
Can I use it with a 12V or 9V device?
No. The SW-242T9 outputs 24V DC. Use only with equipment specifically rated for 24V DC and verify the current, connector, barrel length, and polarity.
Can it power a device that draws less than 2A?
Yes, provided the device is rated for 24V DC and the connector size, barrel length, and center-positive polarity match. The device draws the current it needs.
Is the output regulated?
Yes. This is a switching regulated power supply designed to provide a stable 24V DC output within its rated operating limits.
Is this a wall-mount supply?
Yes. The SW-242T9 uses a wall-mount form factor rather than a separate desktop power brick.
