6V 2.5A AC-DC Power Supply - 2.1mm x 5.5mm Center Positive | SW-62A
Regulated 6V 2.5A AC-DC Switching Power Supply |
Part SW-62A
The SW-62A is a compact, regulated switching power supply that converts standard 100–240V AC wall power to a stable 6V DC @ 2500mA (2.5A) output. With universal input voltage compatibility and the industry-standard 2.1mm x 5.5mm center-positive barrel connector, it's a versatile replacement or upgrade power supply for a wide range of consumer electronics, networking gear, and portable devices.

Compatible Devices & Common Use Cases
The 2.1mm x 5.5mm center-positive connector is the most widely used barrel plug standard in consumer and commercial electronics. The SW-62A is well-suited for:
- Wireless routers and network switches — many entry-level and mid-range routers (e.g. select TP-Link, Netgear, and D-Link models) use 6V DC with a 2.1mm x 5.5mm center-positive adapter
- CCTV and IP security cameras — certain 6V DC bullet and dome cameras use this connector and voltage
- LED light strips and controllers — low-voltage 6V LED installations and RGB controllers
- Portable speakers and audio equipment — select Bluetooth speakers and desktop audio devices rated at 6V DC
- Hobby electronics and development boards — Arduino-based projects, relay modules, and sensor arrays requiring a regulated 6V supply
- Small motors and automation components — 6V DC gear motors, solenoids, and actuators used in robotics and DIY automation
- Replacement adapter for any device originally supplied with a 6V 1A–2.5A center-positive wall adapter with a 2.1mm x 5.5mm plug
Why a Switching Power Supply?
Switching power supplies are more efficient than linear supplies, generating less heat and maintaining stable output voltage even as load varies. The SW-62A's regulated output ensures your connected device receives a consistent 6V regardless of input voltage fluctuations — critical for sensitive electronics, networking equipment, and audio devices.
Frequently Asked Questions
Q: Will this work with my router or network switch?
A: Many entry-level routers and switches use 6V DC with a 2.1mm x 5.5mm center-positive connector. Always verify the DC input label on your device before connecting.
Q: Will this work in countries outside the US?
A: Yes. The 100–240V AC universal input supports use in North America, Europe, Asia, and most other regions (plug adapter may be required).
Q: Is the output center positive or center negative?
A: Center positive (+). The inner pin of the 2.1mm x 5.5mm barrel connector is positive.
Q: My original adapter was 6V 1A — can I use this 2.5A supply?
A: Yes. A higher-amperage supply is safe to use; your device will only draw the current it needs. The voltage must match exactly (6V).
Q: Is this regulated?
A: Yes. This is a regulated switching power supply, meaning the output voltage stays stable at 6V across varying load conditions.
