Frequently Asked Questions

What is the exact input voltage range for the HLK-PM03L module?

The HLK-PM03L accepts a wide-range AC input from 100 to 240 volts at a frequency of 50-60Hz. This makes it compatible with standard mains power in most countries worldwide without requiring a voltage selector switch.

Can this module power a 5V Arduino board?

No, this module provides a fixed 3.3V DC output. It is designed for 3.3V logic devices like ESP8266, ESP32, or sensors. To power a 5V Arduino, you would need a module with a 5V output, such as the HLK-PM01 or a similar 5V model.

Does the module provide electrical isolation between input and output?

Yes, the HLK-PM03L is designed with safety isolation between the high-voltage AC input and the low-voltage DC output. This isolation helps protect sensitive downstream electronics from mains voltage transients and is a key part of its compliance with UL and CE safety standards.

What protections are included in this power module?

The module features built-in output overload and short-circuit protection. If the output current demand exceeds safe limits or a short occurs, the module will automatically limit or shut down the output to prevent damage to itself and the connected load, enhancing system reliability.
