Load capacity and installation
Use 348W as the model’s rated continuous output figure under the specified conditions. Peak-load allowances in the datasheet are time-limited and should not be used as the normal operating load.
Before connecting AC power, set the input switch for the available mains voltage. Check the cabinet airflow and the derating curve, and compare terminal positions and mounting holes when replacing another supply.
Frequently asked questions
Is the LRS-350-12 rated at 350W?
The datasheet gives 348W for the 12V model, with a rated current of 29A.
What is the output adjustment range?
The specified range is 10.2–13.8V. Keep the adjusted voltage within the connected equipment’s permitted range.
Can the peak-load rating be used continuously?
No. The series’ peak-load allowance is time-limited. Use the rated output and applicable derating conditions for continuous load planning.
Can I use either 115VAC or 230VAC input?
Yes, within the stated ranges, with the selector set correctly. The input ranges are 90–132VAC and 180–264VAC; selection is by switch.
