Frequently Asked Questions
What applications is the LRS-350-12 suited for?
The LRS-350-12 outputs 12V DC at 29A, making it appropriate for multi-axis motion control systems, industrial robotics, large LED lighting arrays, and high-current 12V distribution panels. Its 348W output handles heavy continuous loads typical of mid-to-high power automation builds.
Is the LRS-350-12 suitable for use in high-temperature environments?
The LRS-350-12 is rated for operation from -25°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.
How does the LRS-350-12 compare to other voltage options in the LRS-350 series?
The LRS-350 series offers multiple output voltages to match different system requirements. The available variants (with rated power, voltage, and current) are: LRS-350-15: 348W, 15V, 23.2A; LRS-350-24: 350.4W, 24V, 14.6A; LRS-350-3.3: 198W, 3.3V, 60A; LRS-350-36: 349.2W, 36V, 9.7A; LRS-350-4.2: 252W, 4.2V, 60A; LRS-350-48: 350.4W, 48V, 7.3A. The LRS-350-12 itself is rated at 348W, 12V, 29A. All share the same universal input range of 90-264VAC and operating temperature of -25°C to +70°C.
Does the LRS-350-12 meet any vibration resistance requirements?
Yes, the LRS-350-12 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.
How do I determine if the LRS-350-12 has enough headroom for my load?
The LRS-350-12 is rated at 348W output. Best practice is to keep continuous load at or below 80% of rated capacity, which for this unit is approximately 278.4W sustained draw. The 12V output at 29A gives the total current budget across all loads sharing this supply.
