Overview
What it is
The MEAN WELL LRS-100-5 is a 90 W enclosed power supply from the LRS-100 series (100 W Single Output Switching Power Supply). It provides a 5 V DC output with up to 18 A of rated current.
What it is used for
Enclosed supplies like this are mounted inside control panels, machines, LED signage and security equipment racks where a fixed DC rail is needed from mains power.
Key Specifications
- Input range: 85 to 264 V AC, 120 to 373 V DC (Withstand 300 V AC surge for 5sec. Without damage).
- Output: 5 V, 18 A rated current, 90 W rated power.
- Output voltage adjustable over 4.5 to 5.5 V.
- Typical efficiency: 86%.
- Operating temperature: -30 to +70 °C (see derating curve in datasheet).
- Dimensions: 129 x 97 x 30 mm (L x W x H).
Buying considerations
Choose a rated current with headroom above the total load of the connected devices, and check the derating curve in the datasheet if the supply will run hot or at low input voltage. Other output voltages and power ratings in the same series are listed on this page.
Installation considerations
MEAN WELL treats this unit as a component to be installed inside final equipment, so approvals and EMC performance should be confirmed for the complete installation. Wiring, safety and EMC details are in the official datasheet linked below.
