Overview

LRS-100-5 is the 5V output model of this series: rated current 18A, rated power 90W, typical efficiency 86%.

LRS-100 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 3.3V, 5V, 12V, 15V, 24V, 36V and 48V. In addition to the high efficiency up to 91%, the design of metallic mesh case enhances the heat dissipation of LRS-100 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 0.3W), it allows the end system to easily meet the worldwide energy requirement.

Test conditions and notes8

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. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Line regulation is measured from low line to high line at rated load.
5. Load regulation is measured from 0% to 100% rated load.
6. 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.
7. The ambient temperature derating of 5℃/1000m is needed for operating altitude greater than 2000m(6500ft).
8. 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 http://www.meanwell.com)

FAQ

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.

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.

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.

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.

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.
