15V 1A AC-DC Power Supply, Center Negative, 2.1 x 5.5mm Right Angle | SW-151NR
Regulated 15V DC 1A Center-Negative Power Supply | Part SW-151NR
Part SW-151NR is a wall-mount, regulated AC-DC switching power supply with a 15V DC output rated at 1000mA (1A). Its 2.1mm x 5.5mm right-angle barrel plug has center-negative polarity. Use it when replacing a supply for equipment that specifically requires these electrical and connector specifications.
Important: CENTER NEGATIVE. The inner contact is negative (−) and the outer barrel is positive (+). This is not interchangeable with a center-positive adapter. A plug that fits does not establish electrical compatibility. Check the device label or manufacturer documentation before connecting.

Replacement Applications
Your existing product listing identifies Part SW-151NR as a replacement for discontinued PHC Parts D-14600NL and SW-15600N. Verify the connected equipment's power requirements before replacing an older supply; do not rely on the previous adapter's appearance alone.
For service work, repair benches, and custom electronics, select this supply only for equipment documented to accept 15V DC, center-negative power, a 2.1mm x 5.5mm plug, and no more than 1A. No specific pedal, synthesizer, keyboard, networking device, or other equipment is claimed compatible without manufacturer verification.
Compatibility Checklist
- The equipment must require 15V DC, not 15V AC.
- The equipment must specify center-negative polarity.
- The required operating current must be 1A (1000mA) or less, including any manufacturer-specified startup requirement.
- The power jack must accept a 2.1mm x 5.5mm barrel plug; check insertion depth and clearance for the right-angle connector.
- Do not substitute this for a 9V, 12V, 18V, or 24V supply, or a center-positive supply.
Why Choose a Regulated Switching Supply?
A regulated supply is designed to maintain its specified output voltage within its operating limits. For a repair or replacement, the useful feature here is the exact combination of 15V DC output, 1A capacity, and center-negative wiring. Matching all three, along with the connector, helps avoid choosing a visually similar but electrically incorrect adapter.
Frequently Asked Questions
What does center-negative polarity mean?
The center contact of the DC plug is negative (−), while the outer barrel is positive (+). Match this to the polarity symbol on your equipment. Do not connect this supply to a center-positive device.
What types of products can use this unusual rating and polarity?
Only equipment whose documentation specifies 15V DC with center-negative polarity and a compatible 2.1mm x 5.5mm jack can be considered. This may include a repair replacement or custom electronics designed around those exact requirements. There is no verified named-device compatibility list for this listing. If you are selecting a supply for a pedal, audio processor, synthesizer, or other device, send us its exact identification and a clear photo of the power-input label so the requirements can be checked.
Can I use it for a standard 9V center-negative effects pedal?
No. Matching polarity and plug size is not enough. This supply outputs 15V DC, so it must not be used for a device that requires 9V DC unless the device manufacturer explicitly permits 15V operation.
Can a device that draws less than 1000mA use this adapter?
A lower-current device can be considered if it requires regulated 15V DC, center-negative polarity, and the correct connector. The 1A rating is the supply's maximum output capacity, not a requirement that the device draw 1A. Confirm any startup-current requirement as well.
Which discontinued PHC parts does this replace?
The existing replacement reference is for Parts D-14600NL and SW-15600N. Check the equipment's voltage, DC input, current, connector fit, and polarity before installation.
Is this AC output or DC output?
It accepts 100–240V AC input and supplies regulated 15V DC output. It is not a 15V AC transformer.
Will a 2.5mm x 5.5mm jack work with this plug?
Do not assume compatibility. This plug has a 2.1mm inside diameter, not 2.5mm. Confirm the equipment's jack dimensions and required insertion depth before ordering.
Can I use this outside the United States?
The stated input range is 100–240V AC. Confirm the destination's mains voltage and that the wall-plug arrangement is suitable; a physical plug adapter may be needed. Input-frequency and regional approval details are not specified in this listing.
