Voltage matching and cabinet planning
The 4.2V and 5V versions are separate models with different rated power and adjustment ranges. Match the module’s required operating voltage before comparing current capacity. Set the AC input switch to suit the available mains supply before use.
Plan ventilation around the fan and review the temperature derating curve. The quoted working-temperature range does not mean that full rated load is available at every temperature. The original specification download below includes the electrical table and mounting information.
Frequently asked questions
Why is the LRS-350-4.2 rated at 252W?
The datasheet rating for this version is 4.2V at 60A, giving 252W. The LRS-350 family name is not the output-power rating of every voltage version.
Can this model be adjusted to 5V?
No. Its specified adjustment range is 3.6–4.4V. Choose the correct voltage model for the connected load.
Is the input automatically switched between 115VAC and 230VAC?
No. The input range is selected by a switch, with 90–132VAC and 180–264VAC ranges.
Does the 150% peak-load statement for the series apply to the 4.2V model?
The linked datasheet limits that peak-load note to the 12–48V versions. Do not apply it to the LRS-350-4.2.
