12V 300mA Linear Regulated AC-DC Power Supply | PV-1230AR
12V 300mA Linear Regulated AC-DC Power Supply | Part PV-1230AR
Part PV-1230AR is a linear regulated AC-DC power supply that converts 120V AC input to a fixed 12V DC output at up to 300mA. Its detachable 2.1mm x 5.5mm plug is listed with center-positive polarity. It is intended for compatible low-current DC electronics whose voltage, current, connector, and polarity requirements match.

Compatibility & Setup
Compare your device label, original adapter, or manufacturer’s specifications before connecting. The device must require 12V DC, draw no more than 300mA including startup demand, and use a matching connector and center-positive polarity. Device category alone does not establish compatibility.
The listed input is 120V AC, not a universal 100–240V AC range. The output is fixed at 12V DC, not adjustable. Do not substitute this supply for equipment requiring AC output, another DC voltage, a different connector, center-negative polarity, or more than 300mA.
Frequently Asked Questions
Is this a 12V AC or 12V DC power supply?
Part PV-1230AR accepts 120V AC input and provides regulated 12V DC output. It does not provide 12V AC output.
Can I use it with a device that draws less than 300mA?
A compatible device draws the current it needs. A lower-current device may be suitable if its required 12V DC voltage, connector, and polarity match and its current requirements remain within the 300mA rating. Current capacity alone does not establish compatibility.
Does the detachable plug mean polarity is reversible?
The listing specifies a detachable plug and center-positive polarity. Detachability alone does not confirm reversible polarity. Verify the actual plug orientation and output polarity before connecting; do not assume support for center-negative equipment.
Does this support a wide AC input voltage range?
No wide input range is listed. The specified input is 120V AC. Verify your mains supply against the product label before use.
IMPORTANT: Verify the required DC voltage, current, connector dimensions, and polarity before connecting. Incorrect voltage, polarity, or an unsuitable connection can damage equipment. Do not exceed the 300mA rating.
