This project reviews the Hi-Link AC to DC converter modules, focusing on their performance and suitability for powering Arduino projects and other small electronics. These compact converters offer a versatile solution for various applications where a reliable and efficient power supply is needed. The review covers testing at both 110V and 240V input voltages, evaluating their output at 3.3V, 5V, and 12V.

Practical Applications:

• Powering Arduino projects in various locations.
• Providing a stable power source for small electronics.
• Building portable devices requiring AC-to-DC conversion.
• Developing global projects that need to operate on different AC voltages.

Hardware/Components

The review focuses on Hi-Link AC to DC converter modules. Two versions are tested: a 5W version and a 3W version. Both offer 3.3V, 5V, and 12V DC outputs. (in video at 00:15) The physical dimensions of the 5W module are 38.2mm x 22.9mm x 18.2mm, while the 3W module is 33.4mm x 20.2mm x 15mm. (in video at 01:22) The modules accept input voltages ranging from 100V to 240V AC. (in video at 00:40)

Wiring Guide

The modules have clearly labeled AC input pins and DC output pins. (in video at 00:56) The connection is straightforward: connect the AC input to the appropriate voltage source and the DC output to your device. %%WIRING%%

Live Project/Demonstration

The reviewer tests the modules extensively, measuring voltage, current, and power output at different input voltages and load conditions. (in video at 04:34) The 5V modules are tested at both 110V and 240V input, demonstrating stable operation within their rated power capacity. (in video at 05:33, 07:45) The 12V module is also tested, but it shows limitations at higher power levels, failing to consistently deliver its rated 5W output. (in video at 09:12) The reviewer notes that the 12V module has a built-in protection mechanism that shuts down the output when overloaded. (in video at 10:35) The reviewer also checks for isolation between the AC input and DC output, confirming that they are electrically isolated. (in video at 04:10)
