Part PV-91AP is an AC-DC linear power supply rated for 9VDC output at 1000mA (1A), with 120VAC input and a 2.1mm x 5.5mm center-positive barrel plug. Use it as a replacement only when your equipment's electrical requirements and connector match.
Key Features & Specifications:
- Power Supply Type: AC-DC linear power supply.
- Output Performance: 9VDC at 1000mA (1A) rated output.
- Input Voltage: 120VAC. This is not listed as a universal 100–240VAC input supply.
- DC Plug & Polarity: 2.1mm inner diameter x 5.5mm outer diameter barrel plug, center-positive (+).
- Part: PV-91AP.
Typical Technical Applications:
- Replacement Power: For equipment specifying a compatible 9VDC supply, no more than 1000mA current, a 2.1mm x 5.5mm barrel connection, and center-positive polarity.
- Repair & Maintenance: A replacement candidate when the original adapter's ratings and the equipment manufacturer's requirements match the specifications above.
- Bench & DIY Projects: For projects designed for these electrical ratings and connector requirements. Confirm the project's voltage tolerance and regulation requirements before use.
Important Compatibility Notes:
-
Polarity Warning: This supply is center-positive (+), not center-negative. Reversed polarity can damage equipment.
- Check Every Requirement: Match DC output, 9V voltage, required current, connector dimensions, and polarity. A plug that fits does not establish compatibility.
- Regulation & Input Frequency: The existing specifications do not confirm regulated versus non-regulated operation or input frequency. Check the adapter label or manufacturer documentation if your equipment requires a regulated supply or a specific input frequency.
- Not an AC-Output Substitute: This supply outputs DC and is not a replacement for equipment requiring 9VAC.
Frequently Asked Questions
What output does Part PV-91AP provide?
It is rated for 9VDC output at 1000mA (1A), with 120VAC input.
What plug size and polarity does Part PV-91AP use?
It uses a 2.1mm inner diameter x 5.5mm outer diameter barrel plug with center-positive polarity. The center contact is positive and the outer sleeve is negative.
How does this differ from Part PV-61P?
Part PV-91AP is rated 9VDC at 1000mA (1A), while Part PV-61P is rated 6VDC at 1400mA (1.4A). Both list a 2.1mm x 5.5mm center-positive plug, but their voltage ratings differ, so they are not interchangeable based on the connector alone.
Can I use it with equipment that draws less than 1000mA?
A lower current requirement alone is not enough to confirm compatibility. The equipment must also accept the supply's voltage behavior, DC output, connector, and center-positive polarity. Confirm regulation requirements and voltage tolerance with the equipment manufacturer.
Is this a regulated or non-regulated supply?
The available specifications identify a linear supply but do not confirm regulation. Do not assume it has the same regulation characteristics as Part PV-61P. Check the label or manufacturer documentation before using it with voltage-sensitive equipment.
Can I connect it directly to 220–240VAC mains?
No. The listed input is 120VAC, not 220–240VAC. Verify the adapter label's input voltage and frequency requirements before connecting it.
Will this work with a center-negative device or a device requiring AC output?
No. This supply has center-positive DC output. It is not a direct replacement for a center-negative supply or an AC-output transformer.
