It shares the same input range and isolation specs but is slightly larger for better thermal management. Q: What is the maximum current at 5V output?A: The 5V variant (HLK-10M05B) can deliver up to 2000mA (2A), enough to power a Raspberry Pi directly. Q: Can I power a Raspberry Pi 4 with this module?A: Yes, the 5V 2A variant provides sufficient power for a Raspberry Pi 4 under normal loads without peripherals. Q: Does it need a heatsink at 10W full load?A: Under sustained 10W load, additional cooling (heatsink or forced air) is recommended for optimal reliability and lifespan. Q: Is the input-to-output isolation the same as smaller modules?A: Yes, all Hi-Link modules provide ≥ 3000V AC galvanic isolation regardless of power rating. Q: Can I parallel two modules for higher current?A: Parallel operation is not recommended due to current sharing issues. Use a single higher-power module or an external DC-DC stage instead. Q: What AC input frequency does it support?A: It supports both 50Hz and 60Hz, making it compatible with global power grid standards. Q: How do I wire the AC input connections?A: Connect the live (L) and neutral (N) AC wires to the input terminals. Always follow proper electrical safety practices and use insulated connections. Q: Can it operate at 10W load 24/7?A: Yes, but ensure adequate ventilation or cooling. The -25°C to +70°C operating range must be maintained for reliable long-term operation. Q: Are the pins compatible with the 5W module footprint?A: Pinout may differ — always check the datasheet for exact pin assignments before upgrading from 2W/5W to 10W modules.
