Cabinet and Replacement Checks
Check the module voltage, total load and wiring before choosing the number of supplies for a cabinet. Account for cable voltage drop and the specification’s temperature derating; the adjustment range should not be used to exceed the module’s voltage limits.
The E model requires 180–264VAC input. Confirm this range when replacing a supply on a different mains system. Use the retained product photos and mechanical drawing to compare the enclosure and mounting arrangement.
Frequently Asked Questions
What is the output rating of LRS-300E-5?
It is rated at 5V DC, 60A and 300W.
Does LRS-300E-5 support 110V or 120V AC?
No. Its specified AC input range is 180–264VAC.
Can I adjust the 5V output?
Yes. The specified adjustment range is 4.5–5.5V. Set it within the connected module’s requirements.
How tall is the enclosure?
The enclosure is 30mm high, with overall dimensions of 215 × 115 × 30mm.
How many LED modules can one supply power?
That depends on each module’s specified load and the installation conditions. Use the 60A/300W rating together with wiring losses and derating requirements; no fixed module count applies to every display.
