Selection and fault-recovery details
Match the 48V output to the equipment specification and leave clearance for the cooling fan. The manufacturer’s derating and harmonic-current application notes are part of the selection requirements in the downloadable PDF.
The 48V version has different protection recovery behavior from the lower-voltage versions shown in the same datasheet. Its overload, overvoltage and overtemperature protection can latch the output off; the specification calls for reapplying power to recover after the fault is addressed.
Frequently asked questions
What is the rated output of the LRS-350-48?
The model is rated at 48V DC and 7.3A, with 350.4W rated output power.
What AC input range does it use?
It uses 90–132VAC or 180–264VAC, selected by switch. Confirm the selector setting before operation.
Does the 48V version recover automatically from every protection event?
No. The datasheet lists latched shutdown for the 48V model’s overload, overvoltage and overtemperature protection, with power reapplied to recover. Address the fault before restarting.
Can I adjust the output for a 24V load?
No. The specified adjustment range is 43.2–52.8V. Select a supply intended for the voltage required by the equipment.
