Wanptek's new NPS-W series products include 4 models, namely NPS306W, NPS3010W, NPS605W, and NPS1203W. The body colors are available in black and off-white. This model is a miniature switching DC power supply. The output voltage and current can be controlled and adjusted by variable resistors respectively, so it provides more convenience and accuracy in the adjustment of voltage and current. The panel also provides high-precision three-window digital tube display of voltage, current and power, so that users can intuitively see the current use status and various parameters of the machine

FAQ
Q: Why doesn't the power supply turn on when l just received the package (no response)?
A: 1 Check whether the power cord has output.
2 Use a multimeter to test whether the power supply hasvoltage output.
3 lf there is voltage output, remove the power supply cover and check whether the cable is loose.reinsert and try
Q: Why doesn't the fan of the power supply rotate?
A: Our power supply fans are intelligently temperature-controlled and automatically turn on heat dissipation when the interior reaches above 50°℃, it will start automatically.
Q: The current cannot be adjusted?
A: The power supply needs to be connected to the load to make it short-circuit. Then adjust.
