FAQ

  • Q: What is the input voltage range?
    A: The HLK-2M series supports 85-264V AC, covering 110V (US/Japan) and 220-240V (EU/AU/CN) mains globally.
  • Q: What output voltages and currents are available?
    A: Six models: 3.3V/606mA, 5V/400mA, 9V/222mA, 12V/167mA, 15V/133mA, 24V/83mA — all at 2W max.
  • Q: How does HLK-2M differ from the HLK-PM 3W series?
    A: HLK-2M supports 85-264V AC wide input (global compatible), while HLK-PM is rated at 220V only. HLK-2M suits international products; HLK-PM03/05 suits CN-only 220V applications at slightly higher 3W power.
  • Q: Can this module power an Arduino or ESP32?
    A: Yes — the 5V/400mA version can power most Arduino boards and ESP32 modules at light to moderate load.
  • Q: Does it need a heatsink or cooling fan?
    A: No. The 2W module dissipates minimal heat at ≥70% efficiency and operates reliably via free-air convection.
  • Q: Is the output electrically isolated from the mains input?
    A: Yes. ≥3000V AC galvanic isolation separates input and output — safe for direct product integration without additional isolation circuitry.
  • Q: Can this module run 24/7 continuously?
    A: Yes, designed for continuous operation. Derate to 70% load at ambient temperatures above 40°C for maximum lifespan.
  • Q: What happens on short circuit or overload?
    A: Built-in protection shuts down the output. Remove the fault and the module auto-recovers.
  • Q: Is this module CE/UL certified?
    A: The design is CE/UL compliant and uses UL94-V0 flame-retardant PCB material for product certification support.
  • Q: What's the difference between HLK-2M and HLK-5MB / HLK-10MB series?
    A: HLK-2M delivers 2W — ideal for MCU/sensor standby. HLK-5MB (5W) and HLK-10MB (10W) provide higher current for peripherals like displays, relays, or motors. Choose based on your total load requirement.
