24V 1A AC-DC Power Supply - 2.1mm x 5.5mm Center Positive | SW-241PR
Regulated 24V 1A AC-DC Switching Power Supply |
Part SW-241PR
The SW-241PR is a compact, regulated switching power supply that converts standard 100–240V AC wall power to a stable 24V DC @ 1000mA (1A) output. With universal input voltage compatibility and a standard 2.1mm x 5.5mm center-positive barrel connector, it's a reliable replacement or upgrade power supply for a wide range of commercial and industrial devices.

Why a Switching Power Supply?
Switching power supplies are more efficient than linear supplies, generating less heat and maintaining stable output voltage even as load varies. The SW-241PR's regulated output ensures your connected device receives a consistent 24V regardless of input voltage fluctuations — critical for sensitive electronics and monitoring equipment.
Frequently Asked Questions
Q: Is this a direct replacement for the Leviton Energy Monitoring Hub A8812 power supply?
A: Yes. The SW-241PR is the preferred replacement power supply for the Leviton EMH A8812 (UPC: 078477558058), matching its 24V DC @ 1A specification with a 2.1mm x 5.5mm center-positive connector.
Q: Will this work in countries outside the US?
A: Yes. The 100–240V AC universal input supports use in North America, Europe, Asia, and most other regions (plug adapter may be required).
Q: Is the output center positive or center negative?
A: Center positive (+). The inner pin of the 2.1mm x 5.5mm barrel connector is positive.
Q: Can I use this for a 24V LED strip?
A: Yes, provided your LED strip draws 1A (24W) or less. For higher-wattage LED installations, you'll need a higher-amperage 24V supply.
Q: Is this regulated?
A: Yes. This is a regulated switching power supply, meaning the output voltage stays stable at 24V across varying load conditions.
