Replacement and Compatibility
Use the PV-980A only with equipment requiring 9VDC, 800mA or less, a 2.1mm x 5.5mm connector that accepts a 9.5mm barrel, and center-positive polarity. Confirm every specification on the equipment label or in its manual before ordering. Do not use it with equipment requiring AC output, center-negative polarity, a different connector size, or more than 800mA.
Frequently Asked Questions
Can this replace any 9V adapter?
No. The voltage, AC versus DC output, current requirement, connector dimensions, barrel length, and polarity must all match the equipment.
Can I use it with equipment rated below 800mA?
Yes, provided the equipment requires 9VDC and draws 800mA or less, and the connector size, barrel length, and center-positive polarity also match.
Is the output AC or DC?
The output is 9VDC. The input is 120VAC.
What does center positive mean?
Center positive means the inner contact of the barrel plug is positive and the outer contact is negative. The connected equipment must use the same polarity.
