Whenever I want another Wouxun SPS31WIN TYT TH-1380+ 20A (30A) Switching Power Supply W/ Noise Offset Control, but I know the XYL will question where it came from, I just make sure its the same colour as the last. I then say that's the same one from a year ago. Works every time :)

Use your Wouxun KG-UV920P / UV-950P, TYT TH-9000D, TH-7800, TH-8600, TH-9800 or other mobile radio indoors as a base station with this 12V switching power supply. 20 Amp of continuous power is available, with a max burst of up to 30 Amps. Great for VHF/UHF Mobile Radios and QRP HF Radios.
This power supply is available from both TYT and Wouxun. It is the same power supply, different brand name.
*** Noise Offset Volume Control ***
This allows you to adjust the pulse noise of the switching circuits of the power supply. Specifically designed for communication devices, like radios. This helps to reduce "noise" associated with traditional switching power supplies. Effectiveness varies by frequency and mode.

Ask a Question
  • Does the Wouxon power supply have connections on the rear and if so what type?

    The rear of the power supply has a single pair of terminals to accept either a bannana plug, or unscrew to attach bare wire.
