Mean Well LRS-100-5 Power Supply 100W 5V

Q: What applications is the LRS-100-5 used for?

The LRS-100-5 provides 5V DC at 18A, making it suitable for microcontroller boards, single-board computers, USB-standard logic circuits, and embedded systems requiring a 5V primary supply. Its 80W output can drive multiple 5V logic loads simultaneously within a compact enclosure.

Q: Is the LRS-100-5 suitable for use in high-temperature environments?

The LRS-100-5 is rated for operation from -30°C to +70°C, allowing continuous use in demanding industrial environments without forced-air cooling up to the rated temperature ceiling. The unit is designed for indoor installation in ventilated enclosures; it does not carry an IP rating for outdoor or wet-location use.

Q: How does the LRS-100-5 compare to other voltage options in the LRS-100 series?

The LRS-100 series offers multiple output voltages to match different system requirements. The available variants (with rated power, voltage, and current) are: LRS-100-12: 102W, 12V, 8.5A; LRS-100-15: 105W, 15V, 7A; LRS-100-24: 108W, 24V, 4.5A; LRS-100-3.3: 66W, 3.3V, 20A; LRS-100-36: 75.6W, 36V, 2.8A; LRS-100-48: 110.4W, 48V, 2.3A. The LRS-100-5 itself is rated at 80W, 5V, 18A. All share the same universal input range of 85-264VAC and operating temperature of -30°C to +70°C.

Q: Does the LRS-100-5 meet any vibration resistance requirements?

Yes, the LRS-100-5 is rated to withstand 5G vibration, making it appropriate for equipment installed in environments subject to mechanical vibration such as factory floors or mobile industrial platforms. It also operates continuously up to 70°C, covering most harsh industrial ambient conditions.

Q: How do I determine if the LRS-100-5 has enough headroom for my load?

The LRS-100-5 is rated at 80W output. Best practice is to keep continuous load at or below 80% of rated capacity, which for this unit is approximately 64W sustained draw. The 5V output at 18A gives the total current budget across all loads sharing this supply.
