12V 800mA AC-DC Linear Power Supply Center Positive | PV-1280A
Part PV-1280A is a 12VDC AC-DC linear power supply rated for up to 800mA. Its 2.1mm ID x 5.5mm OD barrel plug is center-positive. Check your device's power requirements before replacing an adapter, especially when the plug looks similar to one with a different polarity.
Key specifications
- Input: 120VAC
- Output: 12VDC, 800mA maximum
- Connector: 2.1mm ID x 5.5mm OD barrel plug
- Polarity: center-positive
- Design: AC-DC linear power supply
Check compatibility before ordering
Match your device's label or manual to a 12V DC output, a current draw of no more than 800mA, a 2.1mm x 5.5mm barrel connector, and center-positive polarity. Confirm that 120VAC input is suitable for your location. Plug fit alone does not establish compatibility; do not use with a device requiring AC output or center-negative polarity.
Frequently asked questions
What is the output rating of Part PV-1280A?
It is listed for 12V DC output at up to 800mA. Check your device's voltage and current requirements before use.
Is the plug center-positive or center-negative?
The listed plug is center-positive. Do not use it with a center-negative device.
What size is the barrel plug?
The listing specifies 2.1mm inside diameter x 5.5mm outside diameter. Check both dimensions against your device's jack.
Can I use it with a device that draws less than 800mA?
A device rated for 12V DC that draws no more than 800mA may be suitable if its connector and center-positive polarity also match. Confirm the full requirements in the device documentation.
Does this supply accept 220VAC input?
The listed input is 120VAC. Do not assume it accepts 220VAC; check the markings on the unit before connecting it to power.
