Mean Well LRS-100N2-12 Single Output High Peak Power Supply 102W 12...
Overview
LRS-100N2-12 is the 12V output model of this series: rated current 8.5A, rated power 102W, typical efficiency 88%.
LRS-100N2 series is a 100W single-output enclosed type power supply with 30mm of low profile design. Adopting the full range 85~264VAC input, the entire series provides an output voltage line of 12V, 24V, 36V and 48V. In addition to the high efficiency up to 90.5%, the design of metallic mesh case enhances the heat dissipation of LRS-100N2 that the whole series operates from -30℃ through 70℃ under air convection without a fan. Delivering an extremely low no load power consumption (less than 0.5W), it allows the end system to easily meet the worldwide energy requirement. LRS-100N2 has the complete protection functions and 5G anti-vibration capability; it is complied with the international safety regulations such as TUV BS EN/EN62368-1, BS EN/EN61558-1/-2-16, UL62368-1, BS EN/EN60335-1 and GB4943. LRS-100N2 series serves as a high price-to-performance power supply solution for various industrial applications. Moreover, LRS-100N2 can provide 200% short-duration peak power for motor applications and electromechanical loads requiring much higher power during start-up.

Test conditions and notes5
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
- 3. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
- 4. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
- 5. RCM is on voluntary basis and meets relevant IEC or AS/NZS standards complying with AS/NZS 4417.1.

FAQ
What is the LRS-100N2-12 commonly used for?
The LRS-100N2-12 provides 12V DC at 8.5A, designed for industrial automation controllers, embedded single-board computers, network switching equipment, and IT server accessories requiring a reliable 12V supply. Its 102W output capacity suits moderate to medium multi-load 12V system designs.
Is the LRS-100N2-12 suitable for use in high-temperature environments?
The LRS-100N2-12 is rated for a working temperature of -30°C to +70°C, but full rated load is not available across the whole range: the output must be derated at higher ambient temperatures according to the datasheet's derating curve, which also depends on the input voltage (230VAC vs 115VAC). Working humidity is 20-90% RH non-condensing, and the unit is a component intended to be installed inside final equipment.
How does the LRS-100N2-12 compare to other voltage options in the LRS-100N2 series?
The LRS-100N2 series offers multiple output voltages to match different system requirements. The available variants (with rated power, voltage, and current) are: LRS-100N2-24: 100.8W, 24V, 4.2A; LRS-100N2-36: 100.8W, 36V, 2.8A; LRS-100N2-48: 100.8W, 48V, 2.1A. The LRS-100N2-12 itself is rated at 102W, 12V, 8.5A. All share the same universal input range of 85-264VAC and working temperature range of -30°C to +70°C (with derating).
Does the LRS-100N2-12 meet any vibration resistance requirements?
Yes, the LRS-100N2-12 is rated for 10-500Hz, 5G vibration (10 min per cycle, 60 min each along the X, Y and Z axes), making it appropriate for equipment installed in environments subject to mechanical vibration such as factory floors. Its working temperature range is -30°C to +70°C, with load derating at higher ambient temperatures per the derating curve.
How do I determine if the LRS-100N2-12 has enough headroom for my load?
The LRS-100N2-12 is rated at 102W output; the 12V output at 8.5A gives the total current budget across all loads sharing this supply, reduced at high ambient temperatures per the derating curve. Short peaks of up to 200% of rated power are allowed for up to 5 seconds (duty cycle max. 35%, average power within the rating, at 200-264VAC input; less at 100-132VAC). Output power above 105% for more than 5 seconds shuts the output down.
