Input Connection:
For AC Input: Connect live (L) and neutral (N) wires to AC/L and AC/N terminals.
For DC Input: Connect positive (+) to VIN+, negative (-) to VIN-.
Output Connection:
Connect VOUT+ (5V positive) and VOUT- (GND) to your device.
Safety Notes:
Ensure input wiring is secure and insulated to prevent electric shock.
Do not exceed 600mA output current to avoid overload.
Testing: Verify output voltage with a multimeter before connecting sensitive electronics.
Isolated Power Module: Provides safety and noise reduction between input and output.
Step-Down Conversion: Converts AC/DC 220V input to regulated 5V DC output.
Compact Size: Small PCB design for easy integration into projects.
3W Power Output: Delivers up to 600mA at 5V, suitable for low-power applications.
Reliable Performance: Built-in protection against short-circuit, over-current, and over-voltage.
The HLK-PM01 is a compact, high-efficiency isolated power supply module designed to convert high voltage AC or DC input (85V-265V AC or 100V-375V DC) into a stable, isolated 5V DC output. Its isolation feature (typically with a 4000V isolation voltage) ensures safety by electrically separating the input and output sides, protecting sensitive low-voltage components from high-voltage surges and reducing noise interference. With a maximum output power of 3W (5V, 600mA), it is ideal for powering microcontrollers (e.g., Arduino, ESP8266), sensors, relays, or other low-power devices directly from mains voltage without bulky transformers. The module operates with high efficiency (up to 80%) and includes safeguards like short-circuit and over-current protection, making it a reliable choice for IoT projects, smart home devices, and industrial controls.
Wide Input Range: Supports 85V-265V AC or 100V-375V DC input.
Isolation Protection: 4000V isolation enhances safety and noise immunity.
Low Ripple Output: Clean 5V DC with minimal voltage fluctuations.
Certifications: Complies with international safety standards (e.g., CE, RoHS).
Easy Integration: PCB-mounted design with soldering terminals for quick installation.
