FAQ

1 What are the basic specifications of this 36W switching power supply module
It is an AC-DC step-down switching power supply module based on a double-sided PCB design with an output power of 36 watts providing a stable 12V DC output and a rated current of 3 amperes.

2 What is the input voltage range of the module
It supports wide AC input voltage from 85 to 265VAC or 100 to 240VAC and is compatible with 50Hz and 60Hz mains frequencies.

3 What are the output current, power, and voltage accuracy
The rated output is DC 12V with 3A current and a total power of 36W. The output voltage accuracy is ±1%, the line regulation is ±1%, and the load regulation is ±1.2%.

4 What are the physical dimensions, weight, and mounting hole size
The overall dimensions are 87 by 40 by 25 millimeters and the net weight is approximately 63 grams. There are mounting holes at the four corners with a diameter of 3.5 millimeters.

5 What circuit protection features does this power supply have
It features comprehensive protections including overvoltage protection overload protection and output short circuit protection. When the load is abnormal or short circuited the module will automatically cut off the output to protect the backend circuits.

6 What is its output ripple specification
The output ripple noise of this module is less than 110 millivolts providing relatively clean DC power for backend microcontrollers sensors and industrial control circuits.

7 What is the wiring method for the power supply module
It uses a terminal block socket design. Users can directly insert terminal connectors with crimped pins into the socket or solder matching plugs by themselves for convenient wiring.

8 What application scenarios is this power supply module suitable for
Due to its stable performance it is very suitable for industrial automation control systems internal auxiliary power for industrial equipment and various instrumentation applications.

9 What details should be noted when using this power supply
Although the output is rated at 3A for long term stable operation it is recommended that the backend load current does not continuously stay at the full 3A load and it should be installed in a well ventilated environment.

10 Why is its performance considered more stable and reliable
This power supply module exclusively uses a double-sided PCB design which provides better circuit routing and anti-interference capabilities compared to single-sided boards resulting in higher long term operational reliability.
