Hi-Link HLK-PM01 5V 3W AC-DC Power Supply Module

The Hi-Link HLK-PM01 is a compact 5V 3W AC-DC power supply module designed to convert mains AC into a regulated 5V DC output for embedded electronics, IoT, automation and control applications. It provides up to 600mA rated output current in a fully enclosed PCB-mount package.

Description

The Hi-Link HLK-PM01 5V 3W AC-DC Power Supply Module is a compact isolated switching power module designed to provide a regulated 5V DC supply directly from mains AC.

Its small, fully enclosed construction makes it particularly useful for integrating a power supply directly onto a PCB where a conventional external adapter or larger open-frame power supply is undesirable.

Hi-Link specifies a rated AC input of 100–240VAC with a wider operating range of 85–264VAC. The manufacturer also specifies support for 70–350VDC input.

The module provides a 5V DC output with a rated current of 600mA, giving a rated output power of:

5V × 0.6A = 3W

This makes the HLK-PM01 suitable for many low-power 5V electronics, embedded controllers, sensor nodes and automation circuits where the total load remains within its rated capability. Pakistani electronics suppliers also commonly specify the HLK-PM01 as a 5V/600mA PCB-mounted supply.

220V AC to 5V DC Power Conversion

One of the main applications of the HLK-PM01 is converting household mains voltage into a low-voltage 5V DC rail inside an electronic device.

Typical power flow:

220–230V AC Mains → HLK-PM01 → 5V DC / up to 600mA

Because its official operating range extends from 85VAC to 264VAC, it is not limited specifically to 220V input.

This is why “220V to 5V power supply module” is useful search terminology, while the technical specifications should still state the module's complete input range.

Isolated AC-DC Power Supply

The HLK-PM01 provides electrical isolation between the high-voltage input and low-voltage output sides.

Hi-Link specifies 3000VAC input-to-output isolation, along with insulation resistance greater than 100MΩ under its specified test conditions.

This makes the module useful for properly designed embedded mains-powered products, but isolation does not make exposed mains wiring safe to touch. Appropriate PCB clearances, insulation, fusing and enclosure remain essential.

Technical Specifications

The environmental, input, isolation, ripple and protection specifications above come from Hi-Link's official HLK-PM01 information; the 5V/600mA output configuration is also consistently specified in current module documentation and Pakistani listings.

Protection Features

The HLK-PM01 includes:

Over-current protection
Short-circuit protection with self-recovery
Input/output isolation
Flame-retardant enclosed housing

Hi-Link also recommends an external 1A/250VAC fuse or 10Ω wire-wound resistance on the input side in its technical information.

These built-in features should complement—not replace—proper mains-voltage circuit protection and PCB design.

Applications

The HLK-PM01 5V power supply module can be useful for:

• Embedded electronics
• IoT devices
• Smart-home electronics
• Automation controllers
• Sensor nodes
• 5V control circuits
• Communication equipment
• Instrumentation
• Industrial control electronics
• PCB-mounted power supplies
• Microcontroller-based systems
• Relay-control circuits
• Monitoring systems
• Custom electronic devices

Hi-Link lists industrial control, instrumentation, communications and related electronic fields among the module's applications.

Arduino, ESP & Microcontroller Projects

The 5V output can also make the HLK-PM01 useful as a power stage in suitable microcontroller and IoT designs.

However, compatibility should not be generalized.

For example, some development boards accept 5V through a designated input, while individual microcontroller chips or 3.3V rails may not. Always check the exact board's permitted input voltage and current requirements before connecting the HLK-PM01.

This is more technically accurate than claiming the module universally powers every Arduino, ESP32, ESP8266 or other development board.

Important Load Consideration

The HLK-PM01 is rated:

5V × 600mA = 3W

Therefore, it is intended for low-power 5V loads.

It should not be treated as a replacement for a:

5V 1A supply → 5W
5V 2A supply → 10W
5V 3A supply → 15W

Always calculate the maximum current required by the complete circuit before selecting the power supply.

Safety Notice

This module connects directly to hazardous mains voltage. Installation and PCB integration should only be performed by technically competent persons using appropriate fusing, insulation, PCB creepage/clearance and a protective enclosure.

The low-voltage output should not lead users to assume the AC input side is safe to handle while energized.
